need help with 60' times

Charlie Yannetti · 09-28-2010, 01:14 PM

I think Dave may have hit on it with spinning on the hit.. 6.5 lbs at 2400 lbs sounds at bit low to me.. you might want to try bumping up to 7 or 7.5 before you start chasing ghosts.. if it gets better at 7, then try 7.5..

He would want to lower his air? If he is spinning at 6.5 and you put more air he should spin more. We run 4.7 at day time and if track is good we run 5.0.

This is a door car. I'm sorry we run a dragster. I was reading his post and he could be leaving way to high on rpm's try lowering to 4,000 to 5,000.

I also think you should,

1. Leave at a lower rpm, at 6000, you should be holding a lot in the delay box, leaving at 4000-5000rpm would allow the hit to be more less agressive tightening up your 60ft ets and would just adjust the delay less. Lou is also right about the car being consistent out the door, if not theres your starting pt.and you should get that sorted before using a stop.

2. Does you pedal have a definitive stop on the firewall and does the firewall flex when you pound the pedal.

3. If you shift on time car will also get more consistent as Dave said but having the motor to pull you thru in 2nd gear is important as the convertor gets stressed coming off stop at say 4200 rpm .

4. I run 9 psi in my 16x33 tiresfor s/st, leave at 5200 1st # .05, shifting at .75 at 4100,4200 stop rpm weather dictating.

What kind of stop do you have? On my car I was chasing inconsistent 60' times that would swing about as much as yours. I run an inline stop and it turned out the air cylinder was sticking when it would drop on the stop. So one time it would stick a little as it dropped and the 60 would be way fast, next time it wouldn't stick and it would be way slow.

If you shift on time you may need to leave the rpm up around 4300. There was a good article on Biondo's site about setting up a stop.

One thing I found was a break caliper sticking,thats one thing that took me a while to find. Make sure your car rolls easy,and free. Line locks and a sticky break caliper,will for a fact make 60's jump all over the place. Theres always 100's of reason,and it turns out to be ONE that someone on this site will have had. LOTS of good information on this sight and I thank you all for it.

No one asked about 4 link? Ladder bar settings? Rigid wall tires versus soft? If the going up on air helps that would tell some info.
