GT Motorsports: 370Z Supercharger system development

Valentino · 02-09-2010, 02:16 PM

375 - 385 whp on stock exhaust

kdoske · 02-09-2010, 02:22 PM

390

G37Sam · 02-09-2010, 02:29 PM

I say 500!

BHP

"The GTM Supercharger Will Have three different stages to offer

Stage one will come with C38-61 Trim up to 550 HP
Stage two will come with C38-71 trim up to 590 HP
Stage three will come with C38-81 trim up to 630 HP"

550 bhp: crossing fingers!!!!!!

theDreamer · 02-09-2010, 02:46 PM

I do not think on stock exhaust/cats/etc. this will break into the 400, but with simple bolt on upgrades this will be 430-450 without much change in the SC setup.

Lug · 02-09-2010, 02:53 PM

I say under 431 or over 433.

Buddy Revell · 02-09-2010, 03:02 PM

For the CARB-legal version, I predict about 390 to the wheels on stock exhaust, 415 with a catback.

BLUESLATE · 02-09-2010, 03:04 PM

Right around 400 sounds pretty reasonable for carb kit with stock components.

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.

I say whoever guesses the closest gets a 25% discount on the SC. That wouldn't be too crazy right, LOL!

Uh yea

kdoske · 02-09-2010, 03:19 PM

whats the BSFC rating with this engine under FI? Has GTM said what the dyno numbers revealed?

Edit:
nm, doesn't really matter, I was just curious...

Wrong kit, AAM runs on unicorn not GTM. So funny that you think GTM runs on unicorn, lame...

guess I'll revise my 425whp stock exhaust estimate. Looking around I see our 3.7L has shown to consistantly put down ~425whp @6psi on TT builds (turbo-back exhaust) so I assume 390-400whp would be a safe bet for stock exhaust @6psi on a S/C and MAYBE 425whp with HFCs and 2.5" catback...if infact 6psi is the target boost
