Going to the track in a couple hours. Put on my sfc, lca with relocation brackets, torque arm, and panhard bar on a couple weeks ago. Still running 1.9 60'. This was at 12 psi on the mt et streets. Any suggestions to help me get this down tonight. thank you.

i believe ppl on DRs run more air in the tires. i think its because they work better. try lik 18psi and maybe disconnecting the front sway bar

I'll try that, I ran a 12.3 at 112 with the 1.9. Just looking to get close to the 11 sec time.

Dam 12 psi too low. I run 20 psi it seems like a good number. My car is almost like yours you should be running close to my times. Bring the rpm's up to 15-1800 then smash it and let the converter flash and don't let off lol! You should clock in at high 11's.

Even with the 1.9 sixty, your mph is low for the mods you have. You should be trapping at least 115 mph.

a low psi in a radial can slow ur mph down though

Thats a very low Trap speed for 435 rwhp, i'de be checking the tune, unless your really spinning bad, something seems off.

Are any of the parts adjustable?

I run 18psi cold and the usually come up to 20psi warm. Wonder what your pinion angle is, I would check that if it is positive it could be hurting your 60ft times.

That is what I was getting at

He is on ET streets, not Drag Radials....

Get the PSI up to what you would drive on the street. Make a run then start droping the PSI untill you slow down, 18PSI may be about right. If your suspension parts are adjustable make sure the rear is square and all that good stuff. Are you on a preped track or street night? That has a lot to do with it.

I have time slips from the previous owner of my old 83 BBC car and with a non adjustable torque arm, double adjustable panhard rod, stock springs and shocks and lakewood drag shocks up front it had 60 foot times from 1.6-1.9 on old M&H race masters (the old crummy ones compared to whats out now).

I got the car and with Spohn double adjustable LCA's (made no ajustments), QA1 drag shocks and MT ET street (28/11.5/15) with street air pressure on the motor and night in the cold no burn out I hooked.

This was at like 2500 rpm (foot brake with no power brakes) but the second I floored it I was at 4,000 RPM.

If your torque arm is adjustable put it at like -2. Even with a stock motor on suspension and stickies you should be able to get a 1.8 or better.

arent et streets drag radials??? i thought they were drag radials with a stiff sidewall?

My 60 ft's are in the 1.50's with all stock suspention

Look at at ET street next to a Drag radial. Different tires that react to power different.

ET street side walls are not stiff...... I have owned them and have some in my garage... if you sit on them with to rim or air they will colapse BAD. The Drag radial is more like a regular street tire but is really sticky and can flex but can't flex as much as an ET street or full slick.

thanks for the help, nothing i have is adjustable. it is street night so might have something to do with. Still rocking the stock 2.73's which probably is not helping. I am worried about the tune. had a local shop tune it. Going to leathal performance in san antonio asap.

Couple of questions since something seems way off. Are you on drag radials or et streets, mt makes both. What brand is the stall? What track do you run at, how many ft. above sea level is it?

snakeeater03

iTrader: (1)

et streets, got the stall from performabuilt, came with new tranny. running at little river dragway in temple texas. its central texas. not sure of the elevation

Deerhunter-Z28

Any idea of the DA the times you ran? Something is definitely off, I would start with the tune. You need a gear in a bad way. Assuming you are full weight you should be in the 11.70ish range minimum, faster if you have lightened the car up.

already got the quote from leathal on gears and tune. Im hoping this will solve my problems. Im looking forward to a good launch and that 11 sec pass.

Also in your tune have you or your tuner disabled the drivetrain abuse? The A4 cars have a drivetrain abuse mode in them that if you footbrake the car it activates the drivetrain abuse which limits your torque that the motor makes. I had this very same issue and with the abuse mode on the best 60' I could muster was a 1.88 on the same tires you are running. I turned the abuse mode off after I got HPtuners and flashed the converter from about 2k rpm and I cut a 1.57 60'. I run my ET streets wrinkle wall tire(not the DR's) at 20 psi of air and they dead hooked after a short burnout.
