Effects of heatsoak

[RS Sick]

As I've previously posted about my car hasn't performed well at the dragstrip. I understand this isn't a "drag" car and don't plan on dragging it after i make one decent pass. My question is about the effects of heatsoak on these cars. Like i mentioned, it was 70 degrees but after driving to the track and doing tech inspection they called sportsman class and i went right down. I let the hood free-fall (like a dummy) after the tech inspec and the hood release tab slid over so I couldn't open the hood; therefore car sat there baking for about 20 minutes before my run. I've uploaded a video shot in MX shortly after my intercooler upgrade was complete and it doesn't seem slow, nor did it feel slow.

I know a better tune with more timing/fuel will only take it to another level, but could heatsoak really have robbed about a full second and 8-9MPH in the 1/4? I hit 100 in about 11.5 seconds with soft launch, but it took about 14 at the track.

Heat soak is no joke, will easily rob you of the difference between an OK run and a good run, or good run to great run. Gotta let her breathe and get temps down. Have you gotten your headers ceramic coated or at least header wrapped everything other than the cats? Do you have your belly pan on / done the sportec mod? Considered cutting the hood for heat dispersion? I know there's templates here for the brave at heart, I don't think I could bring myself to chop into the beast's bonnet...

I haven't done the Sportec belly pan mod yet. I saw Pats old DIY post and plan on doing that soon. No way i chop up the hood though!

In cool weather (50 degrees) it takes me 10 seconds to hit 100. Heat soak turns this car turd slow. You need water meth to run full power in 80 degree plus temps, and certainly sitting around at idle will heat soak you heavily.

I live this daily 5 months a year!!!!

you lose boost timing and fuel with higher IAT temps

A little longer than that here. Actually about 2 months that I'm not! Lol Why I'm in process of installing a Devils Own kit now.

52 degrees so I figured good time to run some logs; 2, 3, 31. Timing higher for sure with lower IATs

combined MAF rule of g/s x 1.25 fairly accurate?

if so max of 410 would net right around 512 CHP

[RS Sick]

2nd pull; 3, 31, 115. Car was fast today, Iswing- what's this water/meth kit?

I have been wanting to remove all my shielding to get a closer look at what I can and can not do to my intercooling system. When I had my Cobras I had these tiny fans I think made by Spall in my air to water heat exchanger for the supercharger and it dropped a solid 30* from my IATs while sitting in traffic to where it would typically be 10-20* above ambient. After drag passes the system would cool back to normal temps by the time I hit the timing slip box.
I was thinking if I could add thoes to the back side of the ICs it would make one heck of a change.


So RS Sick, when you launch at the strip how do you do it? Any load up of the engine or do you launch at idle or what?

[lswing]

Devils Own makes a simple solid kit, other fancier more expensive brands out there too. There's a section on the website in my sig, details install.

I almost installed some fans, or direct spray CO2 on the ICs. Water meth works pretty darn good though, so just stopped at that.

My 60' wasn't stellar but got a fairly "safe" IMO for TC launch @ 2.1. Basically left foot brake, start pressing gas once Christmas tree starts, released brake on 3rd yellow. Usually rpm is at 1500 or so; duck-rat-foot or whatever it probably faster

Thanks, I'll check it out.

my logs look better today?

Your 3, 31, 115 group doesn't show until the end. I think ideally your timing won't hit single digits for max power, or at least be 7-9 under max boost.

Here's my 0-100 run, ~10 seconds. 50 degrees out, and I had been driving for about 45 minutes before this, so all was warm. I eased into the launch, just a little gas to get the TC going and then full gas. This is on a moderate tune, about 16psi, stock intercoolers...the car had just been at the shop so everything was buttoned up tight and running great. Since this run I have the Wagner's, a more aggressive tune, and water meth...most of this helps keep power in the summer.

Here's part of log from earlier in the RPM range. Timing was lower down low, and mostly in the teens from 5,840 to redline.

Here's my 0-100 run, ~10 seconds. 50 degrees out, and I had been driving for about 45 minutes before this, so all was warm. I eased into the launch, just a little gas to get the TC going and then full gas. This is on a moderate tune, about 16psi, stock intercoolers...

Good run man, I got your 0-60 about 4.5 or less (with traction control enabled?) and at about 10.4 to 100. I'll need to take another vid once it's below 50 with an actual launch. Looks like my max boost is 2050 or about 1 bar- so I think i'll be lucky to break 10s to 100 with this tune. Maybe APR tune isn't too bad after all and it was my ignorance to heat soak aka the devil.

[LaserSVT]

I have lots of high HP friends (domestics) running meth and its amazing to see the amount of extra boost they can run and keep the IATs down. Still want to dyno mine and get some boost data to try and figure out what tune is in my car and wanted to do just a couple 1/4 mile runs for fun. I appreciate the info on the launch. I dont want to hurt the trans and launch too hard. Id would prefer to spend $3000 on something other than a rebuild. LOL

And you did that with the ESP on? Dang.

Look I hate to be uber newb here but I have to learn somewhere. What is each part of that data-log? RPMs I understand but is the rest boost, IATs, AFRs and what? Just let me know what oder I am looking at. Also, is this the vagcom log David had mentioned to me? Seems I remember 3,31 and 115 he said to help figure out what my tune is doing to help figure out what kind it is.

[RS Sick]

NP, I'm a noob too but enjoy learning.

columns left to right: time stamp, RPM, combined MAF (max out at 364.08 unless measured individually in block 2), throttle valve angle, ignition timing, time stamp, next four columns are lambda or AFR, time stamp, RPM, no idea, boost requested, boost actual.

Boost actual should be close to boost requested all the way up to about 5,200 rpm, after that combo of small snails and back pressure of precats prevent full boost to redline. But this is all based on what I've learned from these forums.

[LaserSVT]

I have a stupid follow up question then, 1960 what? What measurement is that taken in? I know PSI and BAR and N/mm2 but cant figure out what that measurement is.

[DHall1]

Bar minus atm

[DHall1]

My two step launch control ecu has landed.

Testing tomorrow

[LaserSVT]

Bar minus atm

Hello sir, that is the data you said I need to log with my friends vagcom in 3rd from 2500- redline right?

Also I have no idea what that means "Bar minus ATM" I dont know what ATM is nor how much boost in Bar the car is making so i dont understand the equation.

[RKturbo]

logs shows the boost is in millibars. 1psi of boost is 0.01450 mbar. ATM is atmospheric which is 'roughly' 1000 mbar you have to deduct that from boost shown to get actual. Sooo the actual max boost in the log above is 1780-1000 for ATM leaving 780 mbar which converts to roughly 11.3lbs of boost.

[RS Sick]

I have a stupid follow up question then, 1960 what? What measurement is that taken in? I know PSI and BAR and N/mm2 but cant figure out what that measurement is.

1960 Millibar - but this includes atmospheric pressure (aprox 1,000 mbar at sea level) so you have to subtract that. My tune calls for 2060 max, and at 2,500' elevation, my atmospheric mbar is 925. 2060-925 = 1135 mbar or 16.5 PSI.

[RS Sick]

RK beat me to it. But yes, boost tapers to almost 12 psi by redline considering my altitude.

[RS Sick]

My two step launch control ecu has landed.

Testing tomorrow

Built into 10sec tune?

launch video possible?

[RKturbo]

BTW, maybe Dave or one of the other more knowledgeable guys can chime in but that boost seems a little low for a tuned car to me. I think the requested seems about right at about 14lbs. Sure no leaks?

Pretty sure they confirmed boost taper at upper RPMs is normal. Same log- earlier RPM range, confident no leaks.

Nice. Yes, export from Excel as webpage. Open webpage locally and copy content with cursor, then paste into a post on here. Clean up as much as you can in Excel before this. You'll hit the 50k character limit for posting on here.

Above 16-17psi the turbos get way hot, and past peak performance. Requesting high boost, say 19psi, causes the turbos to come on too quick too hard and fizzle out. The goal with this engine is max timing, and not hot turbo air. Get the timing and boost at that sweet spot and hold on! HP increases up the dyno chart just as the boost tapers around 4,500, lovely.
