5500-6000 is plenty IMO no need to rev the shit out of it.

With my door car I start in 1st shift to 2nd and let it roll out after a few seconds and ease out if it.....

Dragster, roll 2nd thru the water and nail it.

2nd gear at 7000rpm. Just long enough to clean the tires. I'm one of the few dragsters that don't burn out across the starting line.

Never was a high speed burnout fan.After the shift and the tires start to pull,ease out of throttle.Just do it same each time IMO.

X2 Roll through the water box and a good 3 foot up onto the dry and blip the throttle in high gear and bring it up to 6000 rpm for about a 3 count, cold weather a little longer hot weather a little less.

With a c6 start the burn out in second gear. No need to put it to the floor but opening the back barrels a little is a good idea. Shift into high before the shift light is okay but as soon as you hit high gear start your internal count. Mine is one thousand one, one thousand two, one thousand three, then let go of the brake while reducing the throttle.

Like others have said make sure you are out of the water box wet zone. I rollout a foot further than the when the starter gives me the fist to stop. Everyone has their own twist on their routine, you need to find your own.

This is the way I did with my c6 to me the John Force burn outs are a waste of good rubber and I am one that can't afford to buy new tires every time I go to the track.

Chirp, and yank... the tires are ready, I find all tires are different, new slicks heat easier than older ones, street slicks (less heat) are different than slicks, as for RPM whatever you are comfortable with...ie: you can heat for longer at a lower RPM and still achieve the temp they like IMO you cannot take all day and it has to be repeatable, so mashing the throttle to an RPM is different than leaning into the throttle to an RPM, consistency is the objective, try different things until they work like you want and temps ( tire and motor) are where you want and make sure it is repeatable.

How ever you do it you do not make a test hit..... The best hit you get is after the burn out I see lots of guys do this and the test hit works great and then they wonder why it didn't grab at the light Rolling Eyes

I don't shift during a burnout. I watched a friend break a pinion shaft right at the shift in the burnout...apparently, when the rear axle made that little "hop" at the shift, well...it tore up a bunch of stuff. Anyway, I figure an all high gear burnout is generally easier on parts. And if a race car can't spin a wet slick in high gear, well...... Rolling Eyes

Anyway, my best advice is DO NOT spin the tires in the puddle. I know, I know, they're trying to wet the tire all the way around, as if it matters. What they're really doing is throwing water up into the wheelwells so that it can drip out at the starting line. These same guys might occasionally wonder why their 60' times are a little inconsistent.

Aside from that, easing out of the throttle before the final hook is mandatory, as said above. And most tire manufacturers will tell you that their tires don't require long smoky burnouts anymore. Just getting them clean and dry is usually enough. Tire tech has evolved, too. That's good news to me because I hate trying to see the tree clearly with a car full of smoke.

Maverick are you still in Michigan or are you living in Bama?
I like your recommendation to just use high gear. I'm going to try that and see how it works.

I'm in 'Bama. Grew up in Bay City....haven't lived there since '85. Got lotsa friends up there, tho. Spent 23 years in Florida, the last 7 1/2 years here.

I've always used high gear only. No need to flog the trans and rear end, and the tire comes up to speed quickly....I just tap the throttle up to 6000, count one, two, three and let it roll out while lifting off the gas. If I get just a wisp of smoke it's enough. I've never seen any real difference in my short times, trying longer and shorter burnouts, but then again, this car will hook on wet grass. So since I'm the guy buying the tires...shorter is gooder. Rolling Eyes
