View Full Version : It's kind of slow compared to other Cobras

I went to the track last night. Here is the numbers on the time sip.
Launched many different ways but what seemed to work best was rev to 2 grand and let up on the clutch quickly but not dump. I shifted at about 6000-6200 and in this instance did not hit the rev limiter or miss a gear. It now has 2500 miles on it, and is bone stock. The temp was about 78 degrees. It chirped the tires going into 2nd and 3rd. Tire pressure was 27 pounds and had only a slight amount of wheel hop.

RT 544 (500 tree)
60' 2.169
330' 6.012
1/8 9.102
mph 78.78
1000' 11.749
1/4 13.944
mph 100.55

Can anyone tell me anything.

I wish I could help more, but something's seriously wrong. My 96 ran times very similar to this (stock) and you have 100 more HP.
I'm going to assume you are not experienced at drag racing. Don't take offense. :) With a 2.1 60', you probably need to launch harder. Try less air pressure. I used to use 16-20 psi in my street tires. Keep lowering them by 2-4 psi and the times should get better. I always had a tough time launching bc you have to get just enough revs to start to slip the tires without going up in smoke. Regardless of the launch, the MPH tells HP and yours should be much higher. Are you mashing the gas to the floor and shifting at the redline? Do a search for other 03s at the strip.

You know what I've been doing stupid at the track... I've been spraying that no stick on the rear fenders and wheel wells and getting it all over the tire threads. The last time out I was wondering why the tach would climb real fast to 6500 and the speed seemed to go no where. That stuff is like spraying antifreeze all over the thread. Whata dumee.
What do you think... could it be the problem?

Looks like wheel spin and not enough revs. Wind that Mod Motor up!!! :D :D

Are you remembering to turn off the traction control?

Your 60' #'s aren't so bad that it indicates your just sitting there spining like crazy but I don't think spraying slippery stuff on your tires is good for you times. Look on the bright side though, you may have found a wheel hop cure.;)

What he said about practice.................but to tell you the truth your 1/8 time and speed are way off. Drop pressure do a small burn out and shift as hard as you can.

Thanks, I realize with each time I go to the track it's getting better.
I lower the tire pressure down to 27 pounds.
the last time out I did...
60' 2.12
330 5.832
1/8 8.820
MPH 82.68
1000' 11.301
1/4 13.424
MPH 105.20

Getting there? This is bone stock at 78 degrees.
Thanks

I lower the pressure in mine to 16-18 lbs. 27 is too much! :doubt:

I hope Tony is not using 16-18 in street tires. I would assume that is drag radials.

You want 21-22 lbs hot. That is the sweet spot on the F1's. Shift at 6100 and make sure traction control is off.

I use drag radials and lower them to 16-18 lbs. I would also recommend in getting a spare set of DRs just for the track. :thumbsup:

Well any slowness here has got to be me.
Dyno results
Bone stock dyno numbers at 82 degrees with 20 min cool down– after a 50 min hwy run.
379.2 rwhp and 362.2 rwtq.
A/F ratio drops into the 11's at 4500 rpms and into the 10's at 5700 rpms
I am happy!
