also, the awe's are more cost effective..you can get a set in the$ 2500 range.

 

I have them on my car. Love them. I can't say enough good things about them.

I'm sure the other tuners have good ones as well, so you probably can't go wrong whatever you choose.

 

bbywu: Thanks for your reply but I can't find the thread... So sorry. I tried searching under his name and by thermal efficiency.... please help if you can. Thanks in advance.

 

I'm using Markski's 4.5 inch intercoolers for my car. I'm running over 600 hp to the tires on low boost and low 700s on high boost. I'm very happy with them and they look great. Almost like fine jewelry. Something you'd like to put on display somewhere where people could enjoy looking at it, not underneath your car.

 

My Proto 700 kit came with 5" ICs. I believe they are identical to TPC's. Pressure drop is less than 0.25 psi at 900 cfm. I'm running 1.5-1.6 max boost.

 

Marks/TPC

 

Not sure if you aware of this or not, but while Protos and TPC's ICs are exactly the same, Mark's (911tuning) are different.

 

For the 997tts use the same ones as on our 996tts... One of our client's car made 1100rwhp and 950+rwtq, my car made almost 1000rwhp and ran 4.59s 60 to 130s as well as 9s in a 1/4... not sure what else can be said....
Here they are on our 997tt... all with 2.5" hard piping to the turbo as well as to the Y pipe.... not to mention the 2.5" complimentary stock replacement Y pipe... look at the kink on the stock Y pipe at the junction to the side hoses that lead to the ICs... its 1.8" ID at best vs. 2.35" ID with our set up... We believe in getting rid of all possible airflow reductions as much as possible... lots of good info coming soon.... do it once do it right...

i feel on my setup the awe's work fine , and ive got low 700 ish hp..Dont feel i need the 5 inchers.

 

To decide which intercoolers best suit your purposes, you need to ask yourself what do ICs do? They do very specific things that affect engine performance. Every tuner or designer should be able to provide you specifics if you ask them the right questions. Read up on thermal efficiency and pressure efficiency. Learn what can and can not be shown on a dyno versus a datalog. Marketing information may look pretty, but in the end, a tuner should be able to provide you hard facts about how well their intercooler extracts heat (thermal efficiency) and maintains flow (pressure efficiency.)

Here's a good start.

Is that Y-pipe a direct replacement of the stock one?

 

I have the full TPC Setup on my car and it is excellent. Intercoolers work very well even in the hottest of temperatures!

Scott , he means tpc or markskis .

 

Yes it is.....
