Opinion on boost and rwhp numbers ?
I have 418 stroker engine done by TSP, 90 lb injectors, squash return style fuel pump, 1 7/8 ARH headers, Borla s-type exhaust, stock heads and intake. Was running v-3 vortech with 7" and 3.33" pulleys. Made 625 rwhp with 8lbs boost on mustang dyno . Over winter did the following upgrades ysi v-7 head unit 7.8" and 3.12" pulleys. What numbers do you think I will be at on boost and rwhp

I haven't paid attention to vortech builds but I would have expected more on 8lbs like 750-800 rwhp it seems like it. a hundred rwhp or less gain on 8 psi seems a little low. I am interested because I am getting ready to do a similar build with a 408 and Procharger.

I made 588 on 7 x 3.33 pulley set up that had 9psi. With 7.8 x 3.47 I made 628 on 12 psi
You should be 16-18 psi with that 3.12

Too many variables to really say, but my LS402, YSI , 8 inch lower, 3.0 inch blower pulley makes 17-18 lbs, and close to 1000 rwhp.
