I got myself a nice little procharger setup going on and I am considering stroking the moter to a 383 with all forged parts. My cousin has an LS1 and is about to drop a procharger on there so in the spirit of competition I must remain ahead of him. If it was done correctly what kind of numbers times can i expect?

I got on 8#'s of boost, 340rwhp/375rwtq @ 5000+ft.
so far and was wondering how others compared etc.

For the record this is on an L98

Thanks guys!!

 

386hp at the ground and 476 torque at 6# boost. this was in a 92 z28 with a TPIS miniram. don't know if it was a 383 though.

 

340HP at 5000ft? What does that correct to at sea level?

 

Im told its a little below 400hp. Not quite sure though. I never could find the SAE conversion chart.

 

I figured that the horespower output would be more than that. Cause I am putting together a D-1X charged AFR 383 with a SuperRam intake. I was told that I should run a 10sec or so quarter and I figured you need more HP than 400rwhp to run 10sec.

 

I run 12's w/ the mods in my sig. Its not a 383, and it doesnt have a superram intake. I can see you running high 10's low 11's with that setup.
