I have nitto dr,s 275/60/15 My question how long of a burn out should I do? I run them @ 15psi on the strip and have to launch @ 4000 or they grab and my car boggs off the line. I have been told to treat them just like normal slicks and do a good smokie burn out, but maybe it's the track at night it seems that every couple of runs I just fry them off the line and outher times they bite awsome. My best 60' is 1.98 with my mods I have been told I should get close to 1.88 any help would be welcome. Also on street nights I doubt they spray the track.
best to date is 12.97@106.87 with the 1.98 60'

I don't think you should shock nittos. Heat them up until they start smoking then play with the launch RPM. Every car is different so try slipping the clutch and try dumping the clutch and see what works best.

I am finding for the most part dumping the clutch at 4000 rpm is what works the best so far because when they hook it's like a kick in the ars

Here is what I like to do. Drive around the water (your front tires will pick up water other wise) and back into the water, go in just enough to get the tires wet and then pull forward just to the edge of the water. I heat the tires until they start to smoke and then hold that for a 3 count. Next I let off the gas and allow the car to roll forward, the idea is to be spining the tires at this point as all you will do is scrap off the nice hot rubber. Launching what I do is hold my rpm at about 5000 and then do a fast slip with the clutch, dumping tends to shock the tires and a dr does not behave like a slick, the sidewall is much stiffer and does not absorb the hit.

how come you got a 28' tire? one reason your bogging could be cause of these tires. also those 60s suck for those tires. seems like those tires are hurting you some. 1.9s can be seen on street tires. your suspsension is in need of attention

I have had a 1.9 60 ft time with 225/50/15's.

I have been told the tires are too tall so in the spring I will get a 50 series dr's. Also this weekend I am putting polly bushings in the control arms, axle and boxing the control arms. S only thing left will be driving practice.
