How much boost do you guys think I will see with an A-trim supercharger with a 2.95" pulley? I see about 5-1/2 psi with the stock 3.33" pulley. Any idea???? ![[patriot]](graemlins/patriot.gif)

You can calculate your impellar speed here:

I didn't know your crank pulley diameter or where you plan to shift or I would have plugged the numbers in.
From there you should be able to plug into the A trim flow table and see what you'll push or...bolt it together and let it rip!

Not sure on the pulley size, but I saw 10psi for quite a while out of my old A-Trim with a power pipe and pulley. I eventually sold the kit in working order for $1,100. Motor was stock with regards to heads, intake, etc....

no. TFS track heat intake, e-cam w/1.7 rockers, and stock heads.

6000 still sounds a little high for stock heads, but maybe that's just me...
