S-Trim 7" Crank users

I finally got mine on, and I was wondering what kinda gains you saw. I'll be running the 2.95upper and hope to see 13psi...Once the TKO is in.
Also the pulley is underdriven so I'll need a new serp. belt, I know the test fit thing, but thought maybe someone else has thie setup and could tell me the belt length to save me some trail/error.

Thanks

I have a 2.95/7.00 set up with Anderson powerpipe, 80mm MAF, 70mmTB, Cobra intake, TFTW heads. See 14psi at 5400' altitude.
I switched back to stock pulley's used a stock belt. I didn't see a real need to sacrifice alternator output.

So the underdriven crank pulley will affect alt. output?

Yeah all that boost is nice.

I thought you said you had underdrive pullies installed? I had a set on mine and didn't like the fact that at idle especially at night my batt was discharging all the time because of the underdrive alt pulley...
