    Do these dyno sheets look right?

    They dont look right to me but what does everyone else think?

    First one is a Trex car with 4.11 gears through a 12 bolt and M6:


    This one is the same car with the only change being a TH350:


    Well first of all were the AF Ratios are on a dyno sheet the scale is wrong. Second Ive never seen a car that had the torque instantly jump then steadily loose it all the way to red line. I guess it just doesnt look right to me.

    Yeah thats F*cked buddy, unless theres a fault in your tranny, or rear end, changing those items shouldn't increase/decrease HP or TQ numbers

    It is very normal to see RWHP go down with a switch from a manual to auto. As for the torque spike at the beginning I would most likely blame that on the converter some how.

    the first graph, someone has forgotten PE delay, so enrichment settles in slowly at the beginning of the pull. The second graph shows that his dyno software is old, because it is reading falsely high tq from the stall speed running up on that unlocked converter. The later WinPep releases don't have the flash peak at the beginning to that extent.

    What is it that is supposed to be wrong with them or the AFR readout?

    I just thought the scale looks wrong to me. I thought AFRs are usually in the double digits not single digits.

    Looks right to me.

    That automatic is sucking driveline power down. BUT making the car faster at the track.

    I see 12.8ish to 13.0ish in the graph you posted.

    I think you got confused by the way the 1's are linked together. That actually is about 12.8.
