What are you guys using for burnout rpm. I watch the in-car camera vids & see many between 6k & 8k.

I was pretty shocked to see that rpm range. I'm at 4,500 & see about 5,000 coming out of the water. I've always thought rpm in the burnout box with little to no load, wasn't good.

Makes a heck of a lot of difference what sort of gear ratio we are talking about. The tire is turning a whole lot slower with a 4.56 final drive ratio than it is with a 3.73 final drive ratio. Take care. Tom Worthington

Wheel speed is needed and wanted in a burn out. Like Tom pointed out, gear ratio matters. With 4.56/4.88 gears in my n/a small block car I look for 5000/6000 rpm for burn outs. At my local track I see a lot of people using low rpm on burn outs. Most see more engine wear and heat due to lugging the engines with the practice.

5500-6000 with a 4.88 and 14x32s

Open wheel car no front brakes I am usually around 7,000 RPM on the burnout. Door car with front brakes lower.

4.29 gear, 104"tire, 2150# car in bracket mode I'm at 5000 during the shortened burn out and leave chipped at 4400. In Super Gas mode I'm at 6000 during the burn out and usually leaved chipped between 5300 or 5400 depending on the D/A.

In my door car I run it up to 5500, shift into second, hold it at 5000 for a second or so and come out of water.

When I ran my dragster that was a different story. High gear and as much wheel speed as I could get.

Start in 1st then immediately into 2nd to 6500-7000 with the s10 but also very short BO

6500 in High Gear

High Gear only 5000..

6000 is my target but I don't use a line-lock, so it ends up being a 'feel' thing if I need a little more to keep them spinning.

I use a 3-step at 6600 and pull out around 7000. I let it eat. 13x32 w/ 5.14

7400 hi gear , 3.89,

First things first, burnouts should be high gear only, regardless of your power level. You have water on the tires, they will spin. If they don't you didn't get enough water on them.

To me the biggest thing is to ensure you aren't tryign to burn out at or below the converters stall speed. I want the RPM above the stall speed for the converter by a decent margin. I don't want to try and burn out when the converter isn't even fully locked up, soon as the tires dry off it will just lug the motor down and tires will stop turning and you end up putting tons of heat in the transmission and converter right before you expect it to work just perfectly for a launch. Low RPM burn outs to me make zero sense unless you are comfortably over the stall speed of the converter.

For me, If the converter flashes to 6000 RPM, I target anything north of 6500 RPM for a door car burn out, hold for a 2 count, then release line lock and power out. A dragster is a little different, i don't care for 3 step burn outs, blowers make low and slow burn outs almost impossible, so its not as accurate and clean in a dragster with injection and a blower. 4 blade injectors are better for throttle control and carburetors are the best, but i refuse to run a carb. I'm 7000 rpm or better in the Dragster for the most part.

If it breaks in the burn out it will break on the racetrack regardless of the RPM you burn out at. Just my opinion.

High range only.

Our popular legend is that you want to reach finish line RPM's during the burnout.

I'll hold the car with the line lock in cool weather, I just dragster it out, in the heat.

It's not like the driver really has a say in this unless you stop and motion to the water box guy, which I will do if it is bone dry.

I always start in Low with the door car since it is heavy and I don't use the line lock. I shift as soon as I know the tires are spinning, which is in the 5500-6000 range.

In the dragster it is High only, shooting for 7000 RPM for a 2-count. I don't like 3-Steps either.

Very interesting differing thoughts & procedures for burnouts! I have seen nothing to change my burnout procedure, not that I was looking to.

Lenny, the driver always has control of the situation when he's sitting in the water box. Once you start your burn out your limited in what you can/can't do, but before you pull in the box or after you roll through and realize there isn't enough water, back up out of the water and make the official put some more water down. I've never been to a track that wouldn't add some water if the box was dry.

High gear only, 7000-7100 rpm

I’ve never been to a track that didn’t put down too much water for me.
