GTM Supercharged 370Z nismo with stock Exhaust & HFC- 414 RWHP 351 RWTQ 91 oct

Z eliminator · 02-01-2011, 07:34 AM

Not impressed with the rwhp #'s. Shumbys car made more rwhp / lb of boost that the nismo did. 414 STD = 397 SAE. on a 6 mt. @ 8lbs. Shumby made 390 STD = 379 SAE @ 6 lbs on a 7 AT. There is a much bigger drive line loss with the 7 AT vs the 6 MT. My N/A makes 309 rwhp SAE. with bolt ons and it a 7 AT. ( 320 STD rwhp @ 700 ft)
Sam what is the elevation of your shop ( ft above sea level).
It will be interesting to see what i make when my Stage 2 gets here.
I was out testing the GTM torque converter on sunday. Car pulls harder with it but it still needs a higher stall speed. The outside temp was 22 degrees. It ran very well especially between 7000 to 8100 rpm. No oil temp issues that day.

Buy a turbo then!
For the note, I have driven the SC z and it is nice, just can't feel the tq like the turbos have. With being a drag strip dude, I would have thought turbo would have been the setup for you.

Actually, the one dyno pull I saw posted that had them back to back, there was only a 5 HP difference.
