    Are 7's possible ?

    Hello, just wanted to see what you guys think my new 1/8th mile time will be with my new mods. My car is a 02 Z28 A4 with a diablo, drop in k&n stock lid, stock 2.73 gear. Everything else is stock. Heres my timeslip from my 8.60 run.


    I have now added a k&n fipk, auburn posi with 4.10's, a trans go shift kit, trans cooler, nitto drag radials, and a 2800 stall. I have a NX wet kit to install later. Without the NX kit what et and mph do you think the car is capable of producing in the 1/8th?

    I agree. Maybe 8.1 if you really nail the launch and everything works perfectly, weather included.

    4.11's may be a little too much gear for an auto car...

    I agree, 4.10's are way too much gear for an automatic. I would go with 3.73's. Your gonna run out of gears and top it out at 90MPH with that high of a gear! And how well would the nitrous run with the gears being that high?

    A larger stall would be better then more gear.

    not going to top it out at 90 mph. i ran 117 in the 1/4 with them in OD. the 11.664 @ 117.67 is with the 4.10 and n2o going into 4th about 60-70 feet before the traps. comparitively, the wife's car traps 120.96 with 3.73. i can out 60ft her car with mine. i can out mph and et with her car vs mine. i now have 3.73 in my car. we'll see tomorrow what the differences will be.

    I have N2O and 3.73. I am hitting overdrive with about 120-150 feet lefted and now I am experiencing torque converter lockup issues. Oh yeah, no issues, it just doesn't do it. Anyways, I have a stock torque converter and with the 3.73s I still have traction problems. 4.10 would just smok'em. It would look really cool. My two cents.
