OVERBOOSTING?

IM GETTING A GREDDY SUPERCHARGER AND AM WORRIED ABOUT OVER BOOSTING MY STOCK ENGINE BECAUSE I HAVE NST UNDERDRIVE PULLIES. WOULD BOOST INCRESE ALOT MORE DUE TO THE S/C PULLEY SPINNG FASTER?

Considering the SCer kits run like 5 or 6 psi at most.. The underdrive wont change it that much.. if at all.. I would think if it did change the bosst at all you might see 8 psi.. which would be fine for the xB motor.

If you have underdrive pullies, you will be running LESS boost

yeah, if the supercharger pully was smaller, you would see more boost, but with the crank pully being smaller, you will see less boost.

and turn the caps lock off.
