I'll agree with my fellow sedan owner. I think right around 400 WHP on the base kit. Possibly a little over....

I am also guessing a price in the $6000-$6500 range. The kit is really no different than most other kits out there. The HKS kit for the VQ35 is $4500 now. If GTM's is anything over the $6000-$6500 price it will be greatly overpriced given the included components. It will also be treading into their twin turbo territory (which is under $8k), which is a much more complex kit with cast manifolds, two turbos, wastegates, BOV's, etc.

Wow...unicorn blood made it over to GTM

ANother no go for the media release! I hope he makes a new thread for the release becuase I am starting to really hate this one!

I am not trying to piss on anyones parade but I think you guys are overly optimistic on the power estimates. I would be suprized if either this kit or the stillen will break much over 400 rwhp.

Have you seen bolt on dynos? With LTH, exhaust, intakes, and a tune you get enough power that anything under 400 whp would just about make this pointless.

It's not just about peak power, it's also about low-end and mid-range torque. Although a tuned naturally-aspirated VQ can put up solid peak numbers, it won't be able to hang with a forced induction kit (even a centrifugal SC-based one) in the rpm ranges where most street-driven cars are at most of the time.

Initial tuning has begun things are going well over all, i did have to stop due to a bad air fuel ratio sensor on bank one yesterday .

That was replaced this morning and I'm back on the car tuning. working on mainly driveability right now and then we will start focusing on power and dyno numbers.

Also we will be adding a boost and air fuel ratio gauge to the car tomorrow to give a better idea what is the car doing while we are taking the videos .

here is couple videos we took today of the car starting and idling, the car is very quite and you can not tell there is a supercharger on it, in a matter of fact you can here the bigger injector over the the whole supercharger system .

Getting close

kdoske · 02-10-2010, 09:57 PM

awesome. When you rev the engine with the hood open you can hear the super charger. Its not loud but you can hear it. Sounds a lot like a factory stock supercharger or turbo.

Nice Sam, thanks for the quick vids, I think it sounds just right, you can hear it but it's not overpowering.

Buddy Revell · 02-10-2010, 10:02 PM

Very subtle. I like that a lot!

We don't even have the air filters on the car in this video, so with the air filters it will be much quieter
