Actually it's 708 BHP and 565 TQ (x-0.15x = 602HP or x = 602/.85) and (480/.85).

That is a horrendous powerband for a "street car". If you didn't "market" this engine as a street engine I wouldn't be so harsh, but a street engine should not start making power at 5000rpm. A bolt on Turbo S has a better curve from 0 to 5000 rpm. Thats huge considering this setup only offers superiority for 2200 rpms. In fact, at 4000, most are over 300 ft lbs to the wheels, 100 ft. lbs higher than your current powerplant configuration. Why have you not raised the compression even higher for more area under the curve? You won't have to run as much boost, and thus you'll have a greater temperature differential when the air enters the plenum, which will give you the power you want and also help suppress detonation.
