    Looking for opinions on what the front end weight should be on a 3.80-3.60 hardtail slipjoint dragster.

    Car weighs 2040 and is a 272" WB Spitzer car.

    Several knowledgeable people have told me 25% or 500-550 lbs.

    I'm having excess wheelie issues, right now I have 470# on the wheels with the front fuel tank and 50# in the nose.

    Thanks for your opinions...……………..

    Wheelie at the start line or further out? You leaving soft and rolling power in? You can use the wheelie bar and timing curve to calm that thing down some.

    not saying you're doing anything wrong, far from it, but why not try lowering the bar a little? gradually. might go quicker by the time you're finished.

    I used to run the bar lower, but it will bite me in the butt once in a while by unloading the tires too much and you know what that does...…..trying to get away from that.

    was the nose weight the same when you ran it lower?
    might be too heavy in front to use the bar correctly.
    I've never been that quick in my old flexy 270" spitzer, only 4.20's w/.970, but I never was more than 275# and used the bar for wheelspeed control and rode it plenty far on every run.

    I didn't have your power, but when I decided to get after mine I was reminded of Garlits old saying: wheelies are just a lack of power.

    If I got after mine hard at the hit I could take weight OFF the nose. I struggled to make enough power at ~30-60' but the more I gave it, the calmer it got. Until it smoked the tires anyway.

    But I gave up and went to a doorcar so what do i know.
