    Only the 1/8th, 75 degrees, very humid.

    60ft-1.993(PB)
    1/8th-8.78(PB)
    mph-79.13

    I am happy, just doing some tuning. Seems none of the 3 or so 99+gt's wanted any part of me, one guy made a dakota go when he was called up, I guess he wanted to run the 7second grand national instead. :D The best GT I saw that night was a 9.6. The car still has more in it, I am running an LS1 TB(first time to test it out), and a custom MAF(which is running very rich, O2 >.94) I guess I need to get a translator, or custom PCM.

      My best before that was a 8.84, but that was in cooler less humid weather. I know the TB has helped some, but the MAF section is very restrictive. My intake tube is 4"(no other reason except it fits my filter easier), but I have to reduce it down to 2.75". My MAF housing is a 3" ABS plastic collar. I epoxied pieces of 3" pipe inside until I dialed in the MAF close enough to keep the ltrims from maxing out. It isn't optimized, just a beta version. I may go to 42lb injectors(that makes the MAF pretty close in a 4" tube), then use a translator from there. Or go to a LS1 MAF(3"), then get some programming done.

      Throttle response is greatly improved. I think that is mainly due to the SC kicking in faster due to the bigger TB blade. I actually redlighted my first run when I powerbraked and lunged forward. I had give more brake pressure to hold it when the SC kicked in.

      Thanks for the compliment. ;)

        Forgot, about fitting one on a L36. Well, I am not sure how much there is to be gained, but I see no reason it couldn't be done. Perhaps a GTP TB would be a better choice unless you have some serious mods.
