Went to track for first time!!!

[2003BlackStang]

Didnt do to good thought. My best run was a 14.3 not to good my first two runs sucked i had no traction because I didnt warm up the tire enough. Did little burn outs but they didnt heat up. My third run which was the 14.3222 I did a big burnout tire were finally warmed uped car lauched hard as hell but i was reving low b/c i had no grip so car booged. RT was .216, 60-2.350,330- 6.218, 1/8-9.345 at 78 mph , 1000- 12.050, 1/4-14.3222 at 99.41. I figure since it was my first time not to bad but i expected to get my lauch down better but time was alright for my first time at the track. Next time I know how to lauch so im expecting much better times. My car is an 01 cobra Bone stock with Drag radials on rear. What do you guys think I should be running?

Your 60' is a little slow. You might try experimenting with air pressure and launch rpm. Where are you running? High altitude?

 

[Cobra Jay]

Not bad for your 1st time. However No offense, but your 60's time on DR's suck. What psi did you have them at, and what are you launching at? I'd say that you should be in the 13.5-13.8 range with good weather, track conditions and a better launch.

Practice,practice,practice.

 

[2003BlackStang]

my launch suck i only rev to 2000 b/c i could grip my firts two runs b/c i didnt heat the tires up enough. My third run when i ran the 14.3 i gripped like a mother f***er then boog b/c low revs. But now i know what to do next time what would you guys rev up to on the launch??

I second that...get the 60ft to about a 1.9-2.0 and your E/T will come down.

 

[Cobra Jay]

Set your rear psi to like 15 and your front to 40 and do a longer burnout (around 5-8 sec. ) and launch at 4K. If that doesn't help, play with the rear pressure and launch rpm til you find tghe sweet spot.

It just takes practice. Be patient, You'll get it.

not to bad my first trip down the 1/4 was 13.6 at 106 with traction control on which hurt my times. that was stock




89-718 convert. BBK cia, flowmasters
03 SVT Cobra K&N, Magnaflow c/b, SLP 2.81, Fluidyne intercooler,NGK-TR6, SCT dyno tune.

I'd watch out launching at 4k on DR's and the stock IRS...you'll need a trailer to get home...

I forgot, you have an Independent Retarted $hitspension! My mistake. Yeah forget what I said about the 4k clutch dump. Those things make a huge mess and hold up traffic in the staging lanes whan they come apart at the starting line.

The first thing I would do if I bought a 99-04 Cobra would be to replace the IRS for a Solid Axle. The IRS should have been an option and a Solid axle standard on ALL Stangs IMO

Get yourslef a solid rear axle and build it up like the one in my sig. Now all I have to worry about is the clutch and tranny not breaking. If it does, oh well just something else to upgrade. It's only money right? Can't take it with me when I die.

 

[Snakestress]

those times look like you could get better. I ran a best of 14.7 in my stock 1997 cobra first time i took it to the track. street tires as well. after pulleys and catback i got it to 14.4 (also on street tires) launching at about 2200 rpm.
(Before you make fun of me, my altitude sucks! )

 

[2003BlackStang]

Thanks for all the advice guys I was thinking of launching at like 3000 am i gonna break anything with that?

Don't mean to hijack but I believe this is still in the realm of this topic.

Ok, what is the proper way to burn out? I mean I don't do it much because tires kinda like cost a lot. I can rev the engine and ease out the clutch and do a spin out but don't know how to brake and roast......<long pause for laughs and finger pointing>. Thanks.

Just found this:

Burnout (heat cycle):

When the official gives you the signal, proceed with your burnout. This is done to get your tires free of debris and to bring them up to warmer temperature so they become sticky. This is the way I perform my burnout (I don't have line lock):
I bring the rpms up to 4500 or 5000 and dump the clutch. I immediately move my left foot from the clutch to the brake pedal to stop the car's forward movement. I then maintain my rpms at around 5000 until I begin to see smoke and rpms begin to fall off as tires begin to grip. I then ease up on the gas and quickly move my left foot from the brake onto the clutch. You may now proceed to stage the car.

That's one way of doing a burn out with a manual, but trust me a line-lock is the way to go. It's a lot easier to use and a lot more kind to your rear brakes. A buddy of mine had to replace both rear rotors, and one caliper on his 03 Mach1 from heating up his ET Streets SEVERAL times at the track. He now has a Hurst line-lock installed.

hey back to the subject will i break anything launching at 3000

 

[04_snake]

you don't have to ditch the IRS to have quick E/T's. It just takes practice, experimenting with air pressures, more practice. AirLift bags ($30@) is a cheap way to limit IRS squat which will make you ride on the inner edge of the tire only, at launch, limiting traction. If you are draging your stock clutch, dump wherever you have to get out of the hole, but don't slip it, just sidestep it. Slipping the stocker to help limit spin will smoke it quick, so don't do that.
it gets easier.

 

[chuckstang95]

hmmm is slipping the clutch still bad off the line with street tires as well?

 

[1996COBRA]

just practice your launch, and those times will start to come down... not bad for your first outting.

 

[2003BlackStang]

thx guys

I know it is a method some guys use to get out of the hole, especially with street tires that will spin real easy but it will shorten the life of your clutch bad. Drag clutches have higher heat disk material and it is even bad for them, even though they will last longer. Learn what rpm you need to be at, so you can dump the clutch and not bog or hop or spin real bad and fine tune from there. My fastest time with F1's was 12.2 and I did that with a 2500 dump, it almost stalled, bogged a little and then almost immediately chirped as the Goodyear bit in and I think I had a 1.9 60 ft. I was warned about slippping the clutch so I learned how to get out of the hole without doing that. I have a RAM clutch now and sidestep it at 4000-5500 RPM and get 1.6 60 ft's without slipping the clutch so you don't need to do it.
