    How many rwhp per lb of boost do you guys get?

    It's a pretty straight forward question. Any before and after dynoes? And what model of blower was that?
    1991 LX hatch AOD - Dart block, 3.25" crank, H-beams, Ross pistons, Novi 2k, TW heads, Performer RPM, 75mm TB, 80mm MAF, Bennett cam, 60lb inj., AFM Powerpipe, Kooks LTs, Snow Performance methanol/water injection, enough fuel for the Space Shuttle Discovery

    Old Combo - 148k mile stock bottom end, P&P E7s, AOD, NX wet kit
    428.3rwhp 566.7 rwtq

    i don't have concrete #'s but i think i picked up 70-80 horses with my novi 1000 and powerpipe @ 7psi.
    89 Coupe with parts stacked inside of it and about 30#'s of dust on it with no end in sight. :weird:





    Although I am collecting parts for a 12.5:1 393 :D

    John, I'm thinking of getting my car on the dyno before and after the blower install to get an idea also.

    Brandon, I'd wish you'd hurry up and throw that thing on in the next few weeks and give me a ride so I can make up my mind before the rebates stop.

    The general accepted average gain is 13-14 rwhp per pound of boost.

    HP per lb of boost

    Most of the calculators available indicate these typical numbers:
    unmodified 10hp/lb
    HCI mods 13-17hp/lb

    As in every case, each car is different even with the exact same mods.
