GTM Performance Engineering 370Z SUPERCHARGER KIT PRESS RELEASE

BRUSSO

SAM.... I have had turbo'ed and sc'ed cars including a supercharged e46 m3. With the different power levels of the sc'er and turbo applications which would you recommend for maximum power on a stock block and everyday drive ability with the least oil temp issues if that is even a concern and why ? I know we haven't heard much from the twin turbo'ed guys and i'm assuming it's because of the overheating issues that are being worked out.
I feel that this car would be perfect at 450whp-500whp. Anything over that and traction would be a major issue..... and I have no desire to build a block.
thanks for the info
and great job....
also do you have any plans to run water meth ?

Hey Sam, why did you chose Bosch plastic bypass valve (it looks plastic) over some other forged stuff? For example all of my friends driving BMW 335i and VW's swapped their stock bypass valve with (Forge Motorsport) bypass vavle, here's a link:

Forge Motorsport | Alloy Fabrication

What's the reason that made you go with Bosch bypass valve instead of other brands? And do you think it's ok if the BOV you supply with the kit got replaced with something else if it was made for the same boost level?

SAM@GTM

It is a very effective solution, reasonably priced and widley used in the oem turbo german cars. It had worked very well in all the testing that we have done.

Good ?
Any experiments with C16/E85 also?

We have not played with E85 yet for a couple reasons, lack of gas station that supply that fuel and also the E85 requires some huge injectors 1000cc+ to keep up with the fuel demand that E85 requires. sense we are utilizing the factory ecu that option becomes more challenging .

As for C16 it is a great option for race cars, very specific fuel that likes running lean and loves timing, not for street cars application.

Yes stations are an issue for but if able to get there a great option, I would think 600 cc may cope on a V6, what are the current dutys (approx for your set up on pump)

1000's may not cost that much more if no headroom on say a 600, I would def consider a bigger injector as an option, but hell I cannot afford the kit, just am interested in the ins and outs for sure.
Understand on the tuning side of the bigger injector with limited tables avaliable for setting up delivery and decent idel etc.

C16 is pretty sweet, I was more interested on dyno numbers rather then DD running, maybe a 1/4 on C16.
meth is a good option but I dont personally like filling the tank and worrying about fail safes.

With our turbo system we have made over 600RWHP without any problems, and we have many cars ruining 500 WHP+ on the HR and VHR for last couple years worldwide with stock engine with our GTM flash and still running strong to this day . I think tuning, having efficient system has a lot to do with it. I personally feel 450 to 500 hp is the sweet spot for any street car . and with good driving habits you can get a lot of usage and mileage out of the setup .

Running straight water or water/meth injection system has a lot advantages especially to high compression engine like the Our VQ37VHR. i personally like to use those system as an added safety net more then just a power adder, unless you are doing direct port system witch is the only way taht you really can control and make sure your injected an equal amount of water or water/meth in the engine .

it a lot of fun
