I wondee how much diff is in torque and WHP the premium 928 upgrade for SCi trim versus the sole SI trim is without 928?
And then SI trim WITH 928 is probably better than both of the said listed above I assume!
Like if I did triple pulley swap with no e85 but had 928 premium upgrade on SCi?
And 91 octane.
Pulleys being:
3.0 and 3.47 on supercharger side
9psi pulley on jackshaft side (directly on the otherside of the 3.0 inch)
