GTM, any indication of what HP rating the intercooler is good to?

Thanks.

I'm sorry i was under the impression that the car uses both sensors for fuel, timing, and load calculations, I'm sure you will make it work as i have confidence in your shop i was just curious.

And because of some members....drama has now come to this thread. Thread locked.

Sam,
What are your thoughts on the "equal pressurization" and "equal air distribution" issues that are supposed to arise if the stock intake manifold is used in an SC kit?

1slow370 · 02-01-2010, 12:03 AM

personally i don't even understand that as the stock plenum is mostly open on the inside with the runners crossing each other like if you put your hands together and intertwine your fingers.

So you're saying that the air pressure/distribution would pretty much get evened out once it enters the stock manifold?

By just looking at a dyno graph for a stock engine and how flat the curve looks gives us a good idea of how good the stock manifold is.

Intake manafold tuning is lot more critical in n/a tuning not in forced induction applications.It is the total opposite because you have to relay on the manifold design. So by adding boost to the engine all the air gets evened out in the stock manifold, not to mention the VVEL that makes things even better.

One more thing, if we were trying to make a 1000WHP @40 psi then I would say then yes redesigning the manifold is a must but for what any company with a supercharger kit is trying to accomplish the stock manifold is more then fine .

Just go to our web site http://www.gtmotorsports.com/customer_vehicles.php and you will see a lot of VQ37VHR engine running boost with the stock manifold .

pretty much for the pressure. I could see it affecting an NA application if the tubes were off by a lot as the air would have to flow across from the other throttlebody but for F/I the air tank would be pressurized anyway. So long as there wasn't a huge difference between the tubes it should work itself out so the GTM kit is most likely in the clear

Thanks for the explanation, guys. Looking forward to more info soon.

Haha, I swear I'm not trying to be a trouble-maker, but I really do want to know if that's a legitimate issue or not. And I'm trying to keep my questions about each kit in their own discusssion threads.

Haha, I guess you can mention "other intake manifold designs" vs. the stock one, right?

^^Whatever...When did we all start thinking that commenting on the competition is a bad thing? Thus far all of us have made many speculative comments based on pictures and that's exactly what the spy shots were released for. Even AAM got an early post on this implying it's better to go with a TT setup. A little banter between GTM and Stillen does nothing but give us an experts take on their competition as well as incentives to come out with a very high quality product at a reasonable market rate. I doubt anyone in the SC market is going to think twice if GTM puts out a great product because of Sam's actions. Stillen and GTM are in the market to make $, I'm happy to see that they also don't mind debating and discussing issues like every other member on this board so don't be so damn sensitive!
