Intercooler data? CFM flow? Pressure drop figures?

[RAUDI]

That's an RS4 though.

uhhhh. I can't look at the video at work to verify, but I'm pretty sure that is not true. Someone verify please.

Yep, it's in the name of the video too

Don't think it makes too much difference though, shows the impact of the upgrade...

[RAUDI]

Nubcake. Nice catch. I don't know how I missed that. I do still agree with lswing though. It is still good data for the wagners.

[nitrorocket]

Personally, I feel wagners are a poor design for a street car, 4" is just to thick, needs alot if airflow, and will retain heat longer than a thinner intercooler.

The 3.5" core seems more optimal and is what i have used in the past to make intercoolers. I have been using Spearco cores though, not Bell.

The B5 RS4 test is a valid one. The closest to an actual RS6 test.

The old flow vs temps regulation applies here. I don't really want the IC that flows gobs of air. I want good flow but low IAT temps.

The Audizine link that Yokust provided has some excellent test results. Look at the plot graphs of the flow vs IAT temps. That guy did a fantastic job of data capture.

This graph is pure gold.

And from these results the clear winner is SillyRabbitMotorsports. FTW....clear winner hands down.

Haha, who says made in America costs too much? SRM intercoolers are also the cheapest.

Can someone loan me a set of RS6 intercoolers? I want them to build a set for the RS6. I'm ready to give them my business today. I will order two sets.

[Beardown1]

DHall......I just bought RAUDI's intercoolers.....was going to seal them up as spares. Let me know if you're serious.

[nitrorocket]

What brand cores is that place using? You can buy cxracing chinese cores very cheap, but never seem any testing versus a proven core. Bell and spearco cost $500-600 just for the two bare cores.

[SteveKen]

Note that our stock IC's are somewhat similar to radiators with the end tanks somehow pressed onto the cores. If they were welded, you would see welds. Therefore, the outer dimensions of the end tanks are larger than the outer dimensions of the cores. I'm betting if you were to retain the stock end tanks and weld cores to them, you would gain at least 10mm in width and depth. I'm looking into doing this but haven't pulled the trigger yet.

Who is "Them"? I'm confused. I'm guessing "Them" takes Bell cores and welds them to stock RS6 end tanks?

Unless Silly Rabbit needs them for mocking up a set of custom ICs. If so, Tell them I'll buy a set too and can send them my leaking ICs. Volume pricing maybe?

I've also read that the SRM downpipes were just rebranded ssac ones? Not sure if they do the same with any other products.

[nitrorocket]

Apikol uses stock and tanks welded to 9.4x10x3.5 cores.


Im gonna do the same to mine..

[DHall1]

Send SRM a set of stock RS6 intercoolers for mockup

SRM makes the end tanks custom. Complete custom fitment.

Data does not lie. The SRM data looks good enough for me. Iam down for a set.

[DHall1]

I am also going to talk with SRM about the downpipes....it looks like they had a redesign.

Yes, them=SRM

Exactly, that's why comparison of "stock RS4 vs wagners" may be irrelevant for us - RS4 wagners are 3.5".

Keep this old fellow in mind for a GB- I would be interested

Sure, $999 deposit.....let me know!

[DHall1]

DONE

I just talked to Sean. He has the cores ready to go. These cores on on some of the big hp S4s pushing 700hp and the flow data speaks for itself.

He had the cores custom made just for SRM.

Beardown.....send me your contact info via PM....I need those intercoolers as mockup. EDIT: Lou....you may be closer. Can you pitch in your old ones for mockup? Do they still have the brackets for aux rads? I will pay shipping.

The intercoolers will be custom fit to my personal RS6 so we can make 100% sure they fit correctly. Yes kids, that means I'am taking my car to Sean for the final prototype and fitments.

I would say we are good to go here. Sean is ready and has the cores. Let's get this going.....summer is quickly around the corner.

[lswing]

Sure, guessing around $50 shipping, can sort that later. Don't think they have the brackets on them anymore, will double check, might have them around. Got in and out plastic pieces. You going to redo those also going up in size? Or same faceplate just deeper?
