    Speaking of pushing boundaries...
    Just finished testing the car at 22.3 psi of boost.
    Unreal...

    10.9s is my goal but traction will have to be there. Plenty of power now to do it.

    Smoked the 26 X 10.5 X 15 E.T. Streets like they are an all season tire at speed up to 90 mph. No traction.
    Really dissapointed in the E.T. street tires in a FWD application. Tried different pressure, cold, hot, no difference. Traction similar to other drag radials (not good).

    Put back my 23" X 8.0 X 15 MT full slicks... Now we are talking. Much better spun to 70mph only ! lol
    Yet I need more traction my best 60 foot lsat Saturday was 1.85 average 1.9 - 2.0.
    Just getting a 1.6 60 foot would net me low 11s with the power I had before.

    So I will be ordering taller and wider slicks, and hopefully I will hook enough for a 10 second pass
    with stock injectors, stock MAF, stock engine and stock trans. Running 12.5 a/f ratio on race fuel now.
    conservative timing map and Zero KR.

    So far so good, testing on the street was very conclusive.
