    Acceleration feeling in Third?

    How strong should the V pull on a running start ~40-45 and flooring the pedal in third? It seemed it took me quite some time to get up to 65-70. Say just under 10 seconds as a guess? It was only running about 5 minutes, maybe not enough warm up time. This was the first one I've test driven.

    I was test driving a questionable one, and to me it did not feel like I had an 8 cyl., and 400 horses at my calling... I'm comparing to a 2.5L 4 cyl. smaller 4 door.

    At some point the gearing seemed high to the tight gearing I have that might explain my underestimated feeling?

    If you a coming up through the gears to maximize acceleration you would not arrive at 3rd gear until over 60 mph (64 mph), and 3rd gear is only good until 94 mph. 4th will get you to 134 mph.

    I think you'd be in a better powerband in 2nd there.

    Correction - 3rd goes to 99 MPH. Also, even at 45 MPH, if you floor it in third, you should still feel a lot of acceleration.

    The 94 mph I stated of 3rd gear is 93.6 mph and is calculated based on data contained in the FAQ. The 93.6 mph is consistent with a graph provided by StealthV also contained in the FAQ. I believe the calculations are based on stock tire sizes but I did not reverify that. In any event I believe the 94 mph to be accurate.

    If you are trying to pull hard at 40-45, dont use 3rd. That is perfect for 2nd.

    yep, 2nd gear is your friend at that speed. However, I call the V a 3rd gear car just because of how hard it really does pull from 60+ in 3rd. Put it this way...i put the V on the 1/4 drag strip just to see and I could nearly finish the 1/4 in 3rd.

    The appropriate comparison is to have the 4-cylinder below its powerband and floor it. Can you spell sluggish?

    sounds crazy, but look in the forum at the vid I just posted. I trapped at 106mph and wasn't in 4th long at all, check it out, and no rev limiter hit either.

    I have a virtual dyno program that plugs into the ALDL plug and reads from the ECM. It gives 0-100 mph numbers and you can pick out only the 60-100 time.

    Can't remember the name of the program off the top of my head. I'll try to look for it tonight. You input certain parameters and it produces Hp and Tq curves also. It's very sensitive to the inputs so you can easily lie to yourself. The Hp and Tq numbers are good for an A to B comparison when tuning.
