Most iv seen from a f1r is 990ish on a lsx427 in a vett at about 18psi. Hellbent10s is making 800 + on a stock 6.0 with c16 and a turbo. I would say try it i'm sure it would be fun for awhile.

Dave's"Dadkins" GTO that TJ helped build and tunes makes 825rwhp with a stock LQ9, S372 front mount and 110.

And Blackburns truck is making quite a bit with a BEI 370 and tc78 tuned by TJ.

It pisses me off I have a built motor and f1r at 14psi and I can only keep up with a stock bottom end tbss with a d1. But I had a hand on his build and tuned it..... One of these days I'll turn it up and show him some tail lights

your right on the stall, one of the main reason I ditched the procharger. I tow a big enclosed trailer with mine and the higher stall wasn't the best for my tranny and towing. got the turbo, a built tranny and went back to a stock stall converter. The bigger the stall the better the prochargers work!

Yeah the elevation makes alot more of a difference than most think. I ran 10.65 at 4900' elv 7800' Da with 16psi and 22* of timing. Went down to 600' elv at 2800' Da and went 10.3 on just 14psi, and 19* of timing along with another 100LBS of weight in the truck.
