    dyno results II

    Went back to the dyno again tonight to try to add more timing to get hp more inline with torque. Succeed but ended up putting the old tune back in to be safe because the stock fuel system seemed to be on edge at high rpms at that point with the E85. We didn't notice it on the dyno but once we got it out on the road it was starting to lean out a bit as we went through the gears so I'll leave it at the 620hp/655tq tune until I can get a boost a pump in.



    Final results for the night were 666HP/668TQ

    Mods:
    E85
    Airaid CAI
    2.5/9.17 pulley
    ID850 injectors

    That is awesome!

    Throw some DRs on that bad boy & you have a 10.5 @ the local 1320

    Ya know, there's a movement right now to get these cars over to a true flex fuel car with a tune tat adjusts to the alcohol sensor. Good times for sure!

    DRs were the first mod after I purchased the car. I usually just leave those on all summer

    Yeah I'm planning to go back to the track here soon. I was there a few weeks ago before the lower pulley and E85. The track is around 2,200 ft elevation which is about 1,000 ft above were I live so I'm not sure if that caused it or something else but I threw a check engine light (P1101) on the first pass and it was bleeding boost off to around 10 psi. Never had the issue before but it still managed a 12.1 @ 116

    We disabled the p-valve after the lower pulley install to make sure that didn't happen again. Boost is holding steady now.



    1.8 60ft's weren't great but I can improve on those next time I'm there. I wasn't really warming up the DRs very much

    13.1 air fuel at wide open throttle is a bit scary.... Even for a Non supercharged car......
