My old car had 350ish rwhp, the SPF came with a dyno chart showing 472 at the rear (roush 427r).

On 10 year old rubber, it's unusable at anything over 1/2 throttle in the first 3 gears. I'm looking forward to stickier rubber on this one!

With these light cars I think a centrifugal blower like a Paxton will feel better. A positive displacement blower works great on heavier vehicles like my truck, but it doesn't take much to break the wheels loose on these light cars.

That said if you're going to get around 350 ish ft/lbs torque at the rear wheels, that's probably just right.
