If i had a set of DRs on my car? Also how do you guys suggest I do a burn out.. 1st gear, 2nd gear..

Launch: Push in clutch, put car in gear, give some gas, when light turns green let out clutch floor gas and don't forget where 2nd is. LoL:banana: :doh: But seriously I'm also wondering since I will be upgrading to DR's in the very near future...What do some of you guys with experience on them suggest?!? Also what tire pressures are you running at the track with DR's?!?:dunno: :bump: for a good ? thread.:wave:

1st gear burn out with dr's is usually fine. burn them until you start to see smoke then ride it out.
i usually launched from about 2500 rpm's on dr's. slip the clutch a little and let her rip!

Thanks AMY.. do you suggest pedal to the metal in 1st or would i spin?

you would spin. Basically you have to launch dr's just like street tires only more agressive. Being a radial tire they do not have the flex to absorb the shock of launch like a slick can. But they do use a rubber compound similar to slicks allowing for the heat and stickiness that street tires do not. So it is a compromise.
1st gear burn out till smoke is seen and ridden out. launch at 2500, slipping the clutch to avoid the initial shock of launch, then as soon as your accelerator hits the floor, don't lift it...:D

YES SIR!!!!!!
What tire pressure would you guys suggest running on DR's...I've heard some say 14psi is good. To me that just seems a bit too low?!? I could be wrong tho which is why I come to you.

14psi is fine. i usually ran around that somewhere, never had a problem.
you think that's low, i run my slicks at 8psi! :driving:
Yeah but slicks are a totally different story than DRs. I used to run slicks on mine and my cousins 69 chevy pickup. Those things always looked completely flat when we rolled up to the line.

lol yea they do look flat. so much so that at fall nationals i was waiting in line in the back near the staging lanes and some girl stuck her head in my car to tell me that i had a flat tire :eek:

If you do happen to forget where 2nd gear is, then yes by all means - LIFT IT!!! :D ;)
I run mine at 16psi.
depending on how much bite you are getting you could drop the pressure as low as 10 on dr's if you wish.running a lower tire pressure can give you more traction but you dont want to fold the tire.the best way to see what tire pressure your dr's need is do a burnout in an empty parking lot and read your tire marks.your goal is to have the widest contact patch of rubber on the ground.if you have dark edges on the outer edge then you have too little pressure.if you have a dark stripe in the middle you have too much tire pressure.you want as much of an even patch across for optimal performance .i would start around 12-15 psi and take it from there.alot of factors make a difference on your starting point.car weight,driver weight,tire size,width and compound so you will have to do a little of your own tuning.once at the track and you are ready to make your run pay attention to how the car launches.if you were able to launch hard and had a decent short time then there is enough traction to raise the pressure.usually around 1 psi is more than enough change at a time.you want to run as much tire pressure as you can without spinning them.
as far as launching on dr's...you want to go through the waterbox and roll about 2 feet just passed the crease(where the water sits)pull up on your ebrake without locking it,and rev the motor up.if you have an aftermarket clutch that is more aggressive than stock i would suggest revving up over 4 grand and shocking the tires loose in 2nd gear.second gear burnout will give you alot of traction due to higher wheel speed.you could sit there and spin them 60 mph and get em real hot.assuming that youre on a stock clutch i dont reccommend burning out in 2nd.do it in first and hold the burnout as long as you can to get them hot.they will get hot fast and drag you forward.MY BIGGEST ADVICE ON DR'S IS DO NOT JUMP OFF TEH GAS IN THE MIDDLE OF A BURNOUT!!!!!!!!!!!RIDE IT OUT..if you go past the tree just simply back up.someone will flame you prolly but you will still have axles.jumping off the gas in the middle of a burnout will wreak havoc on your axles .you can launch somewhere around 3500 -4000 on dr's.dont sidestep the clutch...feather it out enough where you wont bog and you wont spin them.about 3/4 throttle in first you shouldnt spin on drags with correct tire pressure and a good burnout.wot the rest of the way
anyway imho thats my beliefs,take it for what its worth and have fun!

We tried from idle to 5500 rpms with the drs at various pressures, and anything over 3k would overpower the dr's, or you'd smell lots of clutch. I've spoken to a few other srt owners and they all have come to the same conclusions. I wouldn't recommend feathering the clutch from anything higher that 3k anyways, just because you are unneccessarily cooking your clutch.
Great post btw, but I have to disagree with you on that point.
maybe i should rectify what i mean...i wasnt very clear on that point.if i stage on dr's i rev my motor between 3500 and 4k letting off and bringing back uptrying to put a little bit of a load on the motor then feather it out on the launch which will drop you down as soon as the clutch starts to grab to around 2k to 2500 and avoid bogging....make any sense?

You never know when it can happen. Could happen on your first run of the season or not at all.
Just be prepared to either have it towed/repaired or have a spare for parking lot repair

The cheapest way of getting rid of wheel hop is too get the full set of GMR stock filled mounts.That includes the tranny mount.They work just as good as solid mounts.We have so much torgue in our cars that its hard not spinning 1st and 2nd gear on street tires.Try getting a wider tire and stickier compound.I run 215's on the stock wheels.I've seen 225's and even 235's on aftermarket wheels that are 7 to 7.5" wide.I'm looking at some 8" HP Racing wide rims now and 235 tires if they clear.Are you talking about street use or track use when you spin the tires?You could just drive around on drag radials.:D

You better think about some coilovers then my friend. I've seen 8" rims clear before but you might not be able to turn as easily.
