Sportec lower air vent mod

[V8weight]

I saw that the Sportec RS600 as well as the intercooler kit come with these lower engine shield vents. I figured I could replicate them for a lot less money, like $8.00. All it took was some 1"x1" angle aluminum, and some 3/16" rivets. First layout a pattern (I used 3/4" masking tape).
http://i722.photobucket.com/albums/ww228/Pellis833/001-6.jpg
Next cut out the openings (I used a pneumatic mini sawzall, but a keyhole saw would work), and then clean up your cuts with a file.

Then cut the aluminum angle stock to fit the openings, mark your holes, drill, then rivet them in place.

I also wanted to redo those rubber brake cooling dams that were scraped off of my lower shield, so sacrificed an Impala front air dam that I found at work. It's a heavy plastic rather than the rubber that they were originally made of.

AWESOME!!!!

Is that gonna help with cooling?
Any interference with the serp belt?

It should help with cooling by creating a pull behind the radiator draw more air through the coolers, as well as blowing cool air that hasn't already passed through the radiator over the entire engine and over the turbo's before it exits the rear of the engine compartment. The angle of the picture lies, the vent doesn't actually come near the serp belt at all. For reference, here's a pic of these vents on the original Sportec RS600 promotional car.

very neat Pat. Now, getting to be time to take off those winter tires soon.

[DHall1]

I see who had fun today.

Dammit I was planting Pygmy Palm trees around the pool and shoveling the rock borders from my 6 ton delivery this week. 15tons coming next week to level and redress the RV parking area.

No more fun in AZ.

I gotta pull my bumper to fix that sensor and that will be the time to cut my lower panel.

[V8weight]

Dave, do you need a plug to fill the remaining hole from the sensor relocation relocation? I have some spares, I keep meaning to mail one out. You may as well clear your side markers, add some vents....make a day of it.

[ben916]

so the front set is angled down and out of the engine compartment and the rear set is angled in and up into the engine compartment... it is difficult to determine but it is more of a confirmation.

also, It looks like 10 fasteners to take that tray out/down?
I remember a thread when I was first lurking about a c/f tray for $7k and it was to assist in cooling (fellow was located in Saudi or UAE)

[Mr Balsen]

I have the same mod on my RS6.
And you can feel the heat going out when the electric fans are on !!!!

[Ruergard]

Very interesting, should help with the cooling. Keep us posted!

Nice job. The Pumas even made and appearance. :applause:

Do these cars have problems with excessive engine room heat? Haven't driven in hot weather yet.

Correct, the front diffuser angles down, the rear angles up. There are actually 14 fasteners retaining the lower engine shield, there are 2 more in each wheel well holding the shield to the wheel liners. All you need is a stubby flat head screwdriver to remove the whole thing.

These things produce massive amounts of heat. For reference, on my way down to Arizona I was flying through the mountains of western New Mexico (the ambient temperature was about 40f) and you could actually feel the heat coming out of the center console after prolonged driving. So much so that it was actually fooling the climate control temp sensor and the air conditioning kept kicking on. Any way you can move more heat out of this engine bay is definitely an attribute.

[JRS-RS6]

That looks really slick Pat. Now I want to do that too maybe after the upgraded brake fluid and looking into the ICs. I'm bit tired after traveling 30 hours though. I Should be back next weekend and perhaps we can meet some time during the week before I have to leave again. Now back to South Park in Germany it's like almost 11 PM here......

James, if you want to do this to your car let me know. I bought 2 extra pieces of angle stock in a different size that I need to return. If you want to add these vents I'll just exchange them for the correct size. I saw the links for where you're staying, wow. If I had to travel for work that would be the scenery I would want to see from my hotel window. Hell, I doubt I'll ever see that on a planned vacation.

[V8weight]

Yeah, that was a Sportec press car, so essentially a brand new car with the RS600 conversion. Makes me sick. You saw the bottom of my car, it looks like it's been driven through a cactus patch compared to that.

[JRS-RS6]

I am interested in doing this when I get back also I have lots of pics from other trips I can show you at some point but I do not have them all with me right now.

[DHall1]

Mr Puma is the man.

And yes, the underhood temps go out of this world in the summer. This vent is a must do on any list. It just so happens summer is on the way for me and I have to take my bumper off anyways to move the temp sensor and touch up some under side scrapes. Doc Winer must have had a favorite spot at school that just scraped the lower tray. Dammit.

Pygmy palms are in and most of the rock is laid down. Arrrrrgh, 75/sunny and I was out there playing Mr Landscaper today.

Am I mistaken, or can't you just pick up a whole crew down there standing outside a home depot for like $50 a day?

[DHall1]

I wont pay the 50.

I may shoot them before they leave for screwing up this that or the other.

[LIRS6]

Nice work! Any issues with respect to water intrusion, say if you are going through a substantial puddle where the tires might splash water up through the openings? Is that an area of concern at all?

[DHall1]

Given the location, I would say no.

Now, if you drove into a lake of water the water would actually be scooped up by the lower rad opening and shoved thru the lower grille and into this cavity. The hole would actually allow water to escape in this situation.

A funny story, back in the early 90s when Chevy came up with the ZR1 Corvette....they made the lower cold air intake too low. Guess what happened? Yep, water got in there and blew some 40,000 dollar marine ZR1 engines. Haha, the dealers could not touch these engines even to adjust valve lash. A new crate engine had to be sent out.

I think the sportec mod is safe for the masses.

Here's two additional photo's of the shield after cutting the holes, the second pic shows two extra cuts that have to be made for clearance of the aluminum.

What about using a piece of mesh to repel rocks?

[V8weight]

What about using a piece of mesh to repel rocks?
I thought about that, but there sould be a ton of air moving out of this thing. Enough to repel a rock? Time will tell. I'll see what I can find as far as some kind of mesh or grate, I have something in mind.

[ben916]

Pat, not all of us have access to an Impala front air dam scraps... what do you suggest as a replacement?

Also that screen thing would be good but what is stopping foreign matter from going into one of the V vents?

Those two pieces that I made for the intercooler outlets from the Impala air dam aren't part of the Sportec modification, they're already on your car. I was just replacing mine because they were chewed up. Or are yours bad too? I don't know what other material would suffice, I walked around Home Depot for an hour looking for some kind of rubber flashing to do the job with no luck. That's when I stopped by the shop and started digging through the un-returned parts of the past bin. I suppose you could just go out and buy some cheap Yosemite Sam back off mudflaps and cut them up.

[DHall1]

Ben,

Cut the mudflaps off your wifes Infinity. Slap those bad boys down there.

Very nice job Pat ! I too would think that a grate or screen might be helpful. With that said, it is great you share your handiwork and ideas with all of us- and I thought you were just a pretty face..;0

[V8weight]

You wanted screens, you got your screens. It said on the package it should repel not only stray rocks and road debris, but also chickens and rabbits. JRS-RS6 came over yesterday and we did his vent mod as well as stainless steel brake lines, and Motul RBF 660 brake fluid on both of our cars, and a trans fluid change on my car.

[V8weight]

Oil temps are still running 15-20 degrees lower (at least in my case, I can't speak for James). There isn't any additional wind noise, as this is an exit for air, not an entrance. When the car's parked and the fans are running, it's absolutely amazing how much hot air is rushing out through the vent.

[JRS-RS6]

Pat summed it up. Temp still down about 20 degrees, no additional wind noise. Tons of hot air comes out when the car is sitting still and the fans are running.

[DHall1]

STOP ALREADY!!!!!

I got to get out in the garage and start cutting.

Oh crap, we're going out with the motorhome this weekend. Oh crap, the grass is starting to grow like crazy. Oh crap, my honey do list is running out the door.

Alright, I got out my crayons and drew a diagram of the measurements for the holes if you're looking to do this yourself. The nice thing is that there is a line molded into the shield that you can use as your rear datum line. The rest is just measurements off of that line.

Is the mesh you guys used steel or aluminum? I have seen a lot of steel mesh at the hardware store, but can't remember if aluminum is common.

Awesome rendering Pat.

I'm not running any mesh in mine, still wide open. James' car has galvanized steel mesh. I couldn't find aluminum mesh anywhere.

[4everRS]

OK just realized this. How is the mesh secured on the front where the alum angle is protruding trough the bottom. Do you have a 1" strip 'sandwiching' it in place?

[MaxRS6]

Dang- Nice schematic! Uhhh- I think I prefer just to fedex my cover to the Pat cave- Would you trade it out for a bright new shiny guitar string??- LOL j/k. I think I could even follow your well laid out diagram and instructions. Again- very nicely done Pat!

Exactly, I had to sandwich the screen in between the 1" angle stock and an additional piece of 1"x1/8" flat stock. You can kind of see it in this pic.

6'x6" roll/section of galvanized steel screen material (what about the rubberized coated version? looks like rabbit fencing)

Pneumatic cutting wheel.

You'll only need one 3 foot section of the 1" flat stock as it's only needed in the front where the angle protrudes down. Rivets do come in different colors, I used the black corrosion resistant coated rivets on both mine and James cars. The coated screen sounds like a good idea, I'd like to see it when you get some. It sounds like you pretty much have everything covered. Don't forget, a 3/16" drill bit, some files wouldn't hurt, and I would probably drill some 3/8" holes in the shield and use a hand or jig saw to cut the openings. If you try to use a cutoff wheel, the plastic melts back together as you go.

I also had some random cracks in the pan and used the pieces I cut out for the vent and riveted them over the cracks as a brace. Worked out pretty slick.

Oh, and contrary to a previous post I made on this thread, the mesh for stucco is galvanized steel, not aluminum as previously thought. Still worked pretty good and has the same pattern as the grill, as if anyone will see it.

so I made a trip to HD for the parts, called John (AUDI5000CSTQ) to see if he was going to do this and if he had a place to install this mod.
$37
galvanized grating = $8.99
flat plate = $8.75
angle plate = $6.64
gloves = $9.99 - cuz I program/type all day and can't very well type with cut up fangers, y'all..

the flat plate was thicker than the angle...

How long was the install?

[V8weight]

How long was the install?
Takes about 1.5 hours, or for a programmer/typist about 2.5 hours :)
I ran into the same issue when we bought the materials for James' vent. We used the 1"x1/16" angle, but could only find 1'x1/8" flat stock.

[4everRS]

Ace Hardware for me:

1x1x48 angle = $6.99 (1/16" thick)
1x1x48 flat = $4.99 (1/16" thick)
Rivet gun = $14.99
Alum rivets = $5.99 (3/16" dia. ; 1/8 - 3/8" range)
Mesh screen = FREE (in-laws had some laying around)

Total = $32.96 before tax

Took me about 2 hours

S I'm sure it would cause you to lose downforce or something like that

[DHall1]

There is a very real reason for the leading edge to point down. Much the same way a rear spoiler points up. It will create a low pressure area behind the spoiler and act to evac the hot air from behind the radiator.

You will also loose that .012 of drag but do you want a cool 4.2tt with 3mph less terminal velocity or a hot 4.2 with 3mph more terminal velocity?

That is the question.

Well, last night Ben and I got permission to "waste" a night at the shop.
We went to my friends Alex's' shop, a master MB mechanic, but keeps my fleet operating.
Having a lift made things so much easier. Ben and I decided we liked the grilled protection but not the internal up angled piece. It looked to be too close to the oil pan, as both of our belly pans already had show through wear why risk driving the metal up into the oil pan.
Ben had a good idea of placing rubber between the grill and metal. Alex used 3M upholstery spray glue to attach the a cut in half rubber bike inner tube to the backing support. Thanks to V8weight's diagram, things went pretty well. First mine took 2.5 hours, then after we knew what we were doing Ben's took 1.5 hours. You will note in the photos we don't use 5 coats of mop and glow on our cars. sorry I don't know how to organize the photos but you get the idea. All and all had fun but I'm still picking metal shavings out of my arms.

64000 dollar question.

Did Ben finally get those brake pads installed?

128000 dollar question.

No brake pads, yet... gonna have Alex evaluate the rotors as it might be past the point, not sure...
I think that it would be better served to get new ones and resurface(if possible) the old ones for a track/race day

more like the 4500 hp question... :)

John, great time! Still have aluminum/metal slivers in my hand from the cut-off wheel..

[V8weight]

you were going to give us your aero lesson.

still waiting


There is a very real reason for the leading edge to point down. Much the same way a rear spoiler points up. It will create a low pressure area behind the spoiler and act to evac the hot air from behind the radiator.

You will also loose that .012 of drag but do you want a cool 4.2tt with 3mph less terminal velocity or a hot 4.2 with 3mph more terminal velocity?

That is the question.
Looks like you already took care of that, I didn't see any room for elaboration. :) John and Ben, looks good. It's cool to see this idea evolve as it goes along. I don't think there are two of these vents on the board that look the same.

[DHall1]

Do we agree on the aero position? I wanted a different perspective but if we agree then time for a beer.

[AUDI5000CSTQ]

What is the aero question?
BTW DOW up 96 in pre-market for Monday
Run DVN run

[DHall1]

Not like we have any skin in the game.

Go DVN Go!! Break 67.30 and its game over rover. We did not break below the thur high on friday. Very, very good. And its always easier to buy chicken dinners with an extra 9k in your pocket. Chicken dinners on John.

Aero and why this works from above..

Alright, time to dig out the crayons again. First of all, don't listen to me, I'm not a physics major, or even educated for that matter, but here's my limited understanding of the aerodynamics behind this vent.

Even when the car is sitting still with the fans running, it is really amazing the hot air that is being blown out of this vent. After taking several hard runs to triple digits, I get out of the car with the engine still running and the fans on, I feel under the pan and there is a lot of heat escaping the vent. Also, after those runs, you can see the oil temp increase, then during a "cool down" drive home, you can watch the oil temp needle going down. This is proof to me that this easy and inexpensive mod is worth way more than what I put in to it.

I am very happy I did this.

[RS6Steve]

Did this today, the distructions were a great help. I ran some logs before hand and will run some more over the next day or so so you can all see the difference, thats if anyone is interested?

I believe there are quite a few interested that haven't done the mod...
Having done this mod, I would be interested in the logs.

Did you use both angles internal/external or external and then flat internal?

[hahnmgh63]

I did the mod last week myself, but I only used the front angle, I'm not really sure the rear one would be required, it may help slightly to direct the airflow but would have to be slight. I used some left over stainless stell venting from the front oil cooler opening on my '74 911 RS clone, it should work great.

I did the same mod on my RS6 and notice exactly the same thing. Yes it is efficient. Period...

[RS6Steve]

I only fitted the external, with flat internal and used Ally grill meshing as the cover. I did not want anything too big as a stone could flick in.

Pic not the best. Used my i-Phone, does not do it justice, I'm quite Impressed with my handy work, We will see what happens.

[ben916]

The interesting observation:

Some are putting the front angle INSIDE.
John and I put the front angle on the OUTSIDE with the flat stock crushing the bellypan, grill, cut-up bicycle tire inter tube glued to the flat stock...
See photos 0101 and 0102 on post #83...

[RS6Steve]

How do I display the Logs? They are in Excel and won't upload, if I copy and paste there are two many lines so I can't post them

[RS6Steve]

Why would you put the front angle inside? That does not make sense... As per the lovely drawing it should be outside otherwise it will not help draw the air out.

Edit: Just looked at the pics you talked about, and don't get what you mean? They are on the front edge also?

Edit again: Just read your post again, I'm stupid.... Don't think it really matters

[ben916]

From EXCEL, save it as a .csv
then open the .csv file in any text editor
then save .csv file again as a .txt file
then open the .txt file in any text editor
Select all (Ctrl key and the "A" key)
Copy it (Ctrl key and the "C" key)
and past it into a post here... (Ctrl key and the "V" key )

presto... I think

sorry that was not clear what I meant by that...

if you look at the first set of photos that V8(Pat) posted, he has the front aluminum angle properly point down (vertical) to the ground thereby creating the low pressure/opening for the heat to get out. So we all are on the same page...

What I am communicating is that he (Pat) put the angle piece (horizontal) that connects to the bellypan INSIDE the bellypan and the rivets outside.

What John and I did was:
Have the horizontal angle piece on the outside of the bellypan and the vertical piece still pointing down as it should.
Then the flat stock for the front is used to sandwich the bellypan, intertube gasket, grill all together...
Doing it this way (and not saying my way is better or worse), there is one solid angle aluminum versus two pieces.

[RS6Steve]

I see what you mean now. I have two peices as a sandwich on the leading edge (One angle and one flat) and one on the rear (flat). Don't think it make and real difference!

If you look at my original pics, as well as the vent that I did for James, the front angle is still one piece, I just notched it in the center between the two openings. Your way is probably less work.

no, you have to notch the inner flat stock as well...

[V8weight]

no, you have to notch the inner flat stock as well...

Ahh, right you are. I'm still not running a screen, but on James, I notched both the front flatstock and the angle. There's no real benifit to doing it my way, I was just copying the pics that I had dug up on the Sportec RS600 cars.

Ya, that's one of the threads that I dug up prior to doing this to try and get a picture of how the vent was laid out.

I think he is the guy that has/had the full Carbon bellypan for $7k....
I am still searching.
I also happened across a thread of a full carbon hood for a group buy of $600 (WTF!?!??!)
Before everyone goes nuts, this was in 2004/2005 so I don't know how much weight this has....

[hahnmgh63]

Factory hood is aluminum so I don't imagine the carbon hood could be worth the slight weight savings, even for that price.

[DHall1]

Pat,

I wonder when I should tell the chaps about my intercooler spray bar idea?

Sorry really long previous post.

The Intake temp is too high in my opinion so lets if the mod helps this aswell as the oil temp, should do.

Logs taken average driving and ambient temp of 18 degrees C.

[4everRS]

Dammit Dave. My wife is going to freak when she hears I have another "little project" on the beast.

Ok, that said - tell me tell me tell me tell me.

Pat,

I wonder when I should tell the chaps about my intercooler spray bar idea?

[4everRS]

Is it like this:

I shuold be able to do some logs Thursday or Friday, car in garage for a Miltek at the minute.

Anyway, thanks for the Graph.

I like the idea of a intercooler spray? New thread I think?

[DHall1]

Thank you.

It has been my idea for quite some time. How exactly to do it has been the problem. We dont have any space.

Our intercoolers get red hot after driving and some heat soak. Heat soak from underhood temps literally bake everything under the hood incl the intercoolers.

Hot intercoolers loose efficiency and just get hotter and hotter over time.

Aqua mist in the intake path is a option. Last resort for me.

Sportec vent is excellent. I want to add a spray bar for the outside of the intercooler. This will act to cool the actual intercooler housing and will greatly increase the efficiency of the unit. Stock or Wagner.

So the question remains how to go about cooling the actual intercooler housing. Lets see if any of you come up with my idea. Very simple idea. Pat knows it.

Let the game begin.

there is a much easier way.

no one is running methanol injection yet on the rs6?

[AUDI5000CSTQ]

OK Dave,
You have forced me to chime in. I am surprised you with a motor home don't know about this.
KISS, I have this on my 5000cstq, works out of this world. Patio misters with a line to the coolant, IC and Oil, I have an "auxiliary" windshield washer with water and alcohol. You can plug in the mister heads anywhere and as many as you like along the line.
I have a dummy switch on the dash and manually turn it on.
I am sure some of you electronic wizards can get a thermal switch going. The system works better than you can ever imagine.
Don't get me started on how well we all did today:hahahehe:

[ben916]

does it involve the prying the $$,$$$ from the CFO????

Winner winner chicken dinner.

Leave it to John. Your 5000cstq must really be a beast.

We shall start a new thread on the topic soon.

I want to retro fit the headlight washer switch to operate my mister system. And yes you could put mister heads on all the heat exchangers out front.

Oh thank heaven for stocks like DVN. Thats all I can say.

KISS, I have this on my 5000cstq, works out of this world. Patio misters with a line to the coolant, IC and Oil, I have an "auxiliary" windshield washer with water and alcohol. You can plug in the mister heads anywhere and as many as you like along the line.
I have a dummy switch on the dash and manually turn it on.
I am sure some of you electronic wizards can get a thermal switch going. The system works better than you can ever imagine.
Don't get me started on how well we all did today:hahahehe:

[JRS-RS6]

Anyway, thanks for the Graph.

You're welcome Steve. I could have done better but my plane was boarding and I had to go.


I did a post on this a few years back but no one "bit".

That's because Global Warming wasn't an issue than. Now we all need to learn how to keep our cool.

[snoopra]

OK, back on the air vent subject. While removing the heat shields to pull drive shaft I noticed small strips of foil be used as a "shield" to reduce/prevent metal/aluminum corrosion. Could be used as a shield for those who can't get aluminum grill for air vent. .02

Aluminum Grill???

I used galvanized steel grill and tin snips...
You COULD go crazy and get the aluminum diamond style stuff BUT you are gonna pay for it...

Well, I ended up doing this mod. After putting it on the car, I was very uncomfortable with how exposed the belts and pulleys are. I know I know, they're not that exposed as some of you have said over and over in this thread. Anyway, I was uncomfortable with it so I ordered a new splash panel at the tune of $350.00 Not cheap for these cars. I am selling mine for $100.00 shipped anywhere in the U.S. It is in perfect shape and has been rounded down in the corners to accomodate the H-Sport Sway bars. PM me if you're interested. Thanks!

I wonder when I should tell the chaps about my intercooler spray bar idea?

I'm not buying this intercooler spray idea. Nope, not without some kind of real world data. Maybe some hp numbers........

[DHall1]

So just how much HP is this little trick worth? hmmm

http://i950.photobucket.com/albums/ad348/03RSTT/RS6pics/DaveRV5-21.jpg


Thank you.

It has been my idea for quite some time. How exactly to do it has been the problem. We dont have any space.

Our intercoolers get red hot after driving and some heat soak. Heat soak from underhood temps literally bake everything under the hood incl the intercoolers.

Hot intercoolers loose efficiency and just get hotter and hotter over time.

Aqua mist in the intake path is a option. Last resort for me.

Sportec vent is excellent. I want to add a spray bar for the outside of the intercooler. This will act to cool the actual intercooler housing and will greatly increase the efficiency of the unit. Stock or Wagner.

So the question remains how to go about cooling the actual intercooler housing. Lets see if any of you come up with my idea. Very simple idea. Pat knows it.

Let the game begin.

[DHall1]

Just a quick update on the Sportec mod.

Temps are hitting 100+ here in hotAZ. The combination of Sportec mod and Aces IV are proving to be a massive improvement in performance from the old beast. No more massive heat soak and the car is at full power in all the heat of the day. Still working on my intercooler spray bar package to water mist the outside of each intercooler.

Okay, I have done mine now, well I did it a few weeks ago now, but not posted anything!.

I will do some more logs when I get a chance. Pics below.. I used grill mesh to cover the gaping hole!

It has most defiantly made a difference, the fan does not come on half a much now. Now for the intercoolers.

[hahnmgh63]

Dhall1, how much AcesIV are you using per tank? I've been using it for over a year now and not sure if I've found the sweet spot. I am getting better mileage per tank but I know the ratio of AcesIV will vary depending on how low my tank is before I fill up next time. I usually try to run it down to 1/4~1/8 of a tank. I usually added 2.5~3 oz per tank.

[JSRS6]

Who did you go through? I remember it being pretty cheap when i had my radiator support for my S4 sent DHL freight...

[AudiRS4ever]

UPS and FedEx both were outrageous.

[ben916]

UPS and FedEx both were outrageous.

so you ordered a new one, so then ask the stealership to ship it for you as they get better rates and then you also have the box it came in...

[DHall1]

I have run about the same mixture. Pat and I were talking about this a few weeks ago. If the Aces is a catalyst then is it only good for one tank? In other words...lets say you fill the tank and add 3oz of Aces. What if you run down to 1/2 and then fill up again. What happens if you dont have the Aces with you? Is there a residual left over to condition the 1/2 tank you added? (we didnt think so) Along those lines, what if you ran down to 1/2 then filled up and added 1.5oz of Aces? Does the Aces only condition the new 1/2 tank? Is this the best procedure (half tank refill) or should you run it down to 1/8th then fill with gas and 2.5oz Aces.

Good question for Brian at BND.

Already tried that. Long story, so I'll make it short. When Audi, or any auto company ships a part like that, it comes special courier. The dealership does not pay for the shipping. When I asked the dealership to send mine they were fine doing it until we called with me right there and asked how much. Because it is so large in diameter, both UPS and FedEx said it has to go by their special courier for big freight. Also, it did not come in a box. It looked like it had been on a car for about 2 years. They showed me some other ones and I'll be damned, they all look like that. Thanks for the advise though.

[p3u]

You know you could have got rid of it locally ;)

I am pretty sure B5 S4 and RS4 already have larger holes cut into the belly pan stock. They do not have the alum lips to help pull the air from the bay. But they do have 6 good size longer holes in this same position

I proceded to drive over it and heard some crackling going on, SH$T !!!

Do the cooling mod while you have it off.
Did you order the 14 Dzus fasteners????????????? hint hint hint

[JSRS6]

14? I guess, if you want extras...get em from genuine. IIRC, they were x2 on Ecs.

[s42ski]

Well - count me as another convert to this mod - took me a while to finally do it ( the mod time was a couple hours) - but it really makes a difference - the amount of heat coming out from under the car is amazing. Butt Dyno seems to notice a difference as well especially after driving for a while (less heat soak)

I also had to order a new "dampening cover" since mine was shot and breaking apart. I was still able to make the mod, but a new one from genuine is on the way.

Dave - talked with Brian at BND. The ACES is a catalyst so you need a certain concentration for it to be effective. If there is less than 2.5/3 ozs per 6 gallons then the effectiveness starts to drop off.

[Mr Balsen]

any idea which will lower temperature inside the engine bay is always usefull on our RS6...

Why are you impressed about the bolts? :S

On a normal summer day, the temp reaches 38 - 40°C. Before the mod, the oil temp reached always what I think is 105°C (between the 90°C and 120°C marks). After the mod, the oil temp barely passes over the 90°C mark.
But of course, when I am stuck in traffic with speeds less than 25 km/h the oil temp reaches 105°C again.

with my cover off because of the damned alternator dying, I'm going to do this today. Never used a rivet gun before, but everything looks pretty straightforward.

With Hotchkis bars, the ends of the aluminum need to be rounded off?

Nope. Nice time to do mod.

[Chung]

This thread makes me miss some of people that haven't posted in a while.

[kismetcapitan]

question: if one isn't going to use angle stock in the rear, and I don't plan to, is it really necessary to do flat stock on the rear edge? Probably good for strength, but seems to me that it isn't required.

then again, if Sportec used angle stock pointing upwards, it might be for a reason (to help direct radiator air out the hold by blocking it from going further under the engine). The closeness of the belt worries me though. Maybe I'll use 3/4" angle stock there...

[kevin]

I would stick with the original plans. These angles help create high and low pressure areas. Just saying.

[kismetcapitan]

that's what I'm thinking, although people who only put angled pieces on the front edge seem happy.

I'm doing both, exactly as per the Sportec design.

[ben916]

that's what I'm thinking, although people who only put angled pieces on the front edge seem happy.

I'm doing both, exactly as per the Sportec design.

This is exactly what I did, only the front outward angle and flat on the inward side.
It is really too close to the serp belt.

Also, if you purchase a mountain bike inner tube tire and cut it in half, it is essentially a "gasket" between the aluminum bar and the metal "rabbit" wire.
Also, the tiny rivets 1/4" were too small to use, we had to upgrade to the 3/8" rivets, which requires a larger rivet gun...

[kismetcapitan]

parts collected. I found an offset angle, 1/2" x 3/4". I'm going to use that in the rear to give the belt more clearance. Also looked at rivet options and...went with very short machine screws, washers for the plastic side, and red Loctite. I'm currently pondering using fewer screws and then using superglue to help bond the plastic to the aluminum.

I think this might be my weekend project along with installing my sways.

[kismetcapitan]

done! needed a jigsaw and a drill, and I just marked out the holes with a marker and ruler.
http://img.photobucket.com/albums/v191/tobereeno/file-123.jpg

The rear edge does have a lip, but only 1/2" instead of 1" as on the Sportec car - it's splitting the difference between the 1" design and going with nothing. 1/2" is about even with the NACA duct so I think it should be safe enough.
http://img.photobucket.com/albums/v191/tobereeno/file-124.jpg

not the cleanest job by any means, but I broke both my metal jigsaw blades and couldn't trim the rear edge. When I finally got to the holes, I just eyeballed it - my car was about to be finished with the alternator repair and I needed to get this panel back into the shop. Will still do its job!

[lswing]

Don't you need some mesh in there to keep rocks out? Looks good though!

[Chung]

I am going to do the work at my sister's garage since we are already going to be in Vancouver picking up a car for a friend.

[kismetcapitan]

Don't you need some mesh in there to keep rocks out? Looks good though!

I was thinking so, but mesh won't keep out pebbles. The aluminum will also deflect things and there's some pretty strong airflow coming out of the holes. I'd just worry about animals crawling up into the engine while its parked :P

My work was done entirely on my kitchen floor. Well, not the removal and reinstallation of the panel itself :P

I went ahead and added lower vents yesterday. Here are the pictures. I used bolts for easy change if I needed change back. Many of you are from various climates so I should not worry. But with the belts being right there I couldn't help but be concerned about water or snow splashing up there. I figure the belts will start squealing if they get wet and will be the first sign I need to change back.

Everyone's pictures were a great help, notice the laptop with RS6.com open. :)

[mik15]

bought today the necessary materials and tomorrow will be doing this mod, hopefully will see a difference, considering the hot climate here will be very good for the engine, this summer i saw temperatures up to 122F or more so this should really help..:bow:

[mik15]

job done...took me and my friend about 3hrs, an easy DIY but but it takes a bit of time to put together all the bits and bobs...some really hot air it's now coming through these vents, you can barely keep your hand there for more than 30sec, so i am really happy with the result, didn't check the oil temperature but reading the dial on the cluster it seems to be a bit lower, today were about 105-110F here...

[DST]

Anyone in wet/snowy climates done this mod? I live in Alaska and I'm concerned about snow/winter muck getting in there/on the belts, etc. Lots of winter road grime up here. I'd really like some input on actual winter performance from those that DD. I sometimes have to drive through fresh snow before plowing/snow blowing, typically 8" or less, if more than that I'd probably drive the truck.

Feedback appreciated. We don't get hotter than about 75/80F in the summer normally so this mod may not be that important here in AK, but still, cooler = better.

[mik15]

i don't think you need this mod in Alaska, though it won't hurt but you will most likely get some debris in there plus the snow, but again that would get melt instantly considering the enormous amount of heat the engine generates, it might actually work better than a plow :)

[lswing]

Considered it here in Oregon, warm enough 2-3 months out of the year. Might just get another tray for summer and open that one up...afraid of debris rest of the season.

[4everRS]

I'll be doing this on the new beast. Did it to the old one and loved it. Definitely a difference. I had no issues with weather living in central MN.

I don't know if this was taken off by the shop and not replaced (I had numerous issues and arguments with them while the work was being done) or it if wasn't there when I bought the car. I didn't know exactly was I was getting into when I purchased the car but I'm excited to be finally taking care of the car unlike the last 3 owners.

in the spirit of reducing under-hood temperatures, has anyone removed the sound insulator that's on the hood? would that be a good contribution to the goal of having some better cooling in the engine bay?

i had a while back a '08 Cayenne Turbo and those don't come with that sound insulator on the hood, i was initially surprised to see it missing and thought that maybe the previous owner had an accident, however the car had never been in an accident and after checking with Porsche service they confirmed that this is how they come from factory, so i guess that if Porsche didn't fit it for, probably, good reasons and not only because of costs, why did Audi since i am pretty sure it doesn't do any good apart maybe from reducing just a tiny bit the engine noise heard outside but at the price of keeping the heat trapped....

Maybe Cayenne's hood was made out of durable, better heat resistant material?

[hahnmgh63]

I removed the liner in my RS6 3 or 4 yrs ago. When I had the engine out 3 yrs ago I also had my exhaust manifolds Ceramic coated to reduce under hood temperatures for one thing and it seems to help. I have not had any problems with my under hood paint and really don't notice any increase in noise while the engine is idling. I would probably have to have a side by side comparison to tell the difference in noise at idle.

I have not had any problems with my under hood paint and really don't notice any increase in noise while the engine is idling. I would probably have to have a side by side comparison to tell the difference in noise at idle.

I always forget that I had my downpipes ceramic coated, should help! Tried to have the exhaust manifolds done also, but they screwed that up so I just put new un-coated ones on, that was a debacle...coating company sprayed a bunch of crap inside the exhaust manifolds, end of story, sand kept coming out.

Bringing this back to the top because my attention span and search skills are lacking.

I hope to be doing this soon to my brand new belly pan.
