Okay, Im a noob on FI, but maybe someone can learn me on this issue. I noticed that stock dynos are producing 230ish HP and TQ. The ATI SC is showing about 370HP and 300TQ. Why the uneven gains? The Greddy TT at 5.6 psi is showing about 340 HP and TQ, which makes more sense. You would think that at the same boost the HP and TQ would be roughly the same for each method.

Either way, this seems to hint that a good TT setup could bitchslap a SC. At 7psi, the Greddy probably has about 80 more ft-lbs than the ATI at the same boost.

It takes power to make power on a SC. Adding that extra belt on the SC is what kills the torque. Turbos use exhaust to spool. also, superchargers like ati reach max boost at peak rpm vs a TT can reach peak boost at about 2500-3500 rpm.
