vortech supercharger pullies???

[88mustng]

im gettin the s-trim soon and i know it comes with a 3.33" pulley and will put out about 5-6 psi. does anyone know what other size pullies you can put on the s-trim. i have seen a 2.95" pulley, what will that raise the boost to. i am just curios right now for future upgrading if i ever wanted to.

anyone know??

thanks,
steve

I would swap out the lower (crank pulley) to raise the boost if it doesn't already have the 7" pulley. Swapping the blower pulley to a smaller diameter just spins the blower harder and will add to the rpm.

There is a chart on Vortechs site so you can figure out how hard the blower is working based on the compressor maps and rpm range of your combo.
