you can go ask the pettit guys but they're getting 280-300 at 6-9PSI on the kit pulley and 300-330 on the bigger pulley at 11-13PSI (https://www.rx8club.com/showpost.php...postcount=6333). all to the wheels.
Very few people have gotten the smaller pulley to work correctly, but with similar supporting upgrades, it'll make about 300.
The Hymee kit will be about the same.

Didn't mean to stir up a hornet's nest with people bustin' on Mark about power claims. We'll know the final numbers when we see full dyno curves. He did tell us that these latest numbers were on a dyno that connects to the wheels directly (no tires contacting rolling drums). Then there's all the correction factors that must be applied to get true 'apples to apples' performance numbers...besides the dyno's all spin backwards down under anyway, right ![Mdrmed](https://www.rx8club.com/images/smilies/mdrmed.gif)
That all being said, this kit for me is all about driveability and reliability. I just want the power band of the RX pushed up about 50%, with the same shape and throttle response. Plus I want it to last for 100k miles. This isn't about smokin' the tires and ultimate whp...that's what my 600+hp Shelby GT500 is for.

"About 50%"...and I shoud be more specific and say I just want the torque curve shifted up by "about" 50%. Most stock cars put down about 140-150ft-lbs to the wheels...if I get to a peak of 210-220ft-lbs at the wheels, I'm happy. Peak power of 240-250 rwhp is about 40% above most stock dyno's I've seen.
I spend a lot more time driving near the torque peak than the power peak, so that's what's I'm focused on improving, hence the SC approach. Not trying to start a SC vs. turbo argument again. I'm personally biased towards the low end response you get from boost curves created by a SC.

As I said, I'm not trying to argue SC vs. Turbo. I've owned and installed both (BMW 335i, 911Turbo, WRX STi, Subaru Legacy Turbo, Shelby GT500 , Miata w/SC)....
I believe Mark's SC kit suits my requirements better than any of the turbo kits available. WOT Dyno curves don't tell you how a car responds to throttle inputs or 'feels' on the road/track. I personally perfer the SC approach.
