    got the slp underdrive

    put it on last night and love it , with my 2000 stall it really helps out off the line, letting it rev quicker and hit the stall harder, not a big difference but definitly noticable, will take back to the track and note gains

    on 80 degree night 12.9 @109 1.998 60 2.73 gear no spin

    will go back on 80 to simulate same climate

    yeah it slows everything down by 25 % buy the pully itself is smaller so the engine has less enertia, dont worry about the water pump, before if your engine was at 1000 rpm, with the pully the it would act like it was only at 750 rpm, still plenty to run your accesarry
