Nissan 370Z Forum - View Single Post - Can you get to 400 without turbo or super-charger

My initial performance goal is 370hp at the flywheel, which should equate to about 315whp. I know this is easily possible with JUST high-flow cats, cat-back exhaust, and Cobb AccessPort Stage 2. The AP Stage 2 out for the G37 with this setup claims about 11% gain (about 38hp), so I expect the Z will have similar #s.

Adding an intake to this setup with a Stage 2+ tune would more than likely result in another 10-15hp gain, which brings flywheel horsepower close to 400 at the flywheel, but not quite. I think getting 400 even at the flywheel will be tough to do, but maybe with a plenum spacer, pullies, and some other stuff it will be possible. Now, 400whp, that is a whole other story. I honestly don't know if it's possible at all naturally aspirated without doing some major work.
