    Quest for more RWTQ...

    After getting my ported FAST 90/90 installed and the car retuned about 2 weeks ago, I have been on an endless quest to find more RWTQ. I thought for sure, that with the ported FAST 90/90, I would have broke that 400+RWTQ mark, but fell just short of it. Mods are as follows, if you dont see it listed, I don't have it:

    SLP Lid
    SLP Bellow
    FAST 90/90 (ported by Tony Mamo, and more by me)
    Patriot Stage II Ls6 "Style" heads (2.02"int/1.57"ext, 59cc)
    Comp Cams 224/224 .581/.581 @112lsa
    Ls2 Timing Chain
    Ls6 Oil Pump (ported and shimmed)
    XS LT's/ORY
    SLP LM
    HP Tune (RPM in Lewisville, TX)

    Spohn STB
    Spohn LCA's
    Spohn PH Rod

    Stock 10-bolt w/stock 3.42 gears

    __________________________________________________ ___

    I am open to suggestions and opinions about what I can still do to get more RWTQ. I have (but not installed) a TSP 231/237 .598/.595 @112+2lsa cam, as I am wanting to max out my little 224 cam before stepping up.

    Please dont comment on how your car has more TQ than mine, dude your tune this, or dude your mods that. we all know each car reacts differently to the same mods...

    numbers are in my sig...TIA

    bigger cam...small shot of nitrous

    Have you done the free mods? The FRA mod couldn't hurt, with a fast toys ram air or the slp cai i'd think you'd see some gain too. The gain might not be on the dyno but you should see it at speed.

    EDIT: Just saw that you have a bigger cam waiting to go in...my bad

    yes, all FRA mods have been done. they were done by the previous owner...

    some people have suggested true duals, underdrive pulley...

    BTW, i have been considering nitrous. HWS has a pretty solid kit up to 150 shot for @270 bucks. plug and play...
