SS4Ever, there are tons of different types of GM engineers there. The guy you talked to sounds about as informed as a first year college student who bought their civic Si, who recently read a cat back exhaust would be good to put him in the 11s.
The fact is with GM, they always cork up a certain percentage of power, GM usually leaves a lot of power on the table. The main reason for this is that GM doesn't make quiet nor vibration free motors typically. NHV is the acronynm for the day for most paper GM engineers. However... The good news, sinice most of the GM vehicles are over built, then corked up, they respond well to bolt ons. The ONLY thing that matters is rise in volumetric efficiency with each mod done. There are only two motors I know of that don't respond to bolt ons. Its the S2000 motor, and most recent Nissan VQs. Why? Because they are already engineers to make the best power within those parameters, their runners lengths and volumes are already optimized. Their intake already flows enough without it impeding stock performance, as well as their exhausts. So on and so forth. GMs again, on the other hand do not typically share the same passion for extracting everything they can out of a motor, they say, ok here are the specs, we need to get it this quiet. Lets do it easy, and make a muti baffled intake with wird turns and chambers, that'll quiet it down~! ( and it does... for cheap too ) Same with the exhaust. P.S. the non DI motor, GMs drag racing team dumped the Ecotec in a specific class that allowed up to 3.5 liters. They took the 3.6 destroked it, and make 1665 WHP out the first time with it and killed their transmission. They didn't even think they would come close to that number, btw. |

They also converted that engine to forced induction. It was turbocharged. I'm talking about normally aspirated V6's...

I'm just saying that normally aspirated, that V6 won't have to much more power to be gained from what I was informed. Yeah you throw a turbo or supercharger on it of course you're looking at gains of 100hp or more. But a full load of bolt-ons aren't going to give that V6 like 70+ HP which I think alot of you are expecting...

That's why direct injection systems are so expensive to implement. They require very high pressure pumps and lines. That don't come cheap. But, it's worth it. |
