Are Burnouts bad for the engine?

Someone told me that you can do burnouts without wetting your back tires....

Is this the way to do it...

wet the back tires, then put her in Drive or is there a specific gear?

Then hold the brake, then press the accelerator..then ur back tires "burnout"

let up on the accelerator..then put her in neutral and rev her a few times to clean the engine?

 

#1 Doing a burnout on street tires does nothing except make lots of noise, smoke and wears the rubber off the tire.

Burnouts should only be done with slicks since doing a burnout builds heat and melts the rubber making it sticky. Street tires are not designed to heat up so doing a burnout only makes them slippery.

You do a burnout with the tires slightly wet. It makes them easier to spin and it doesn't wear the rubber off as quickly. A dry burnout is very hard on tires.

At the track you're directed through the water box and stopped at the edge. A race car usually uses a line lock to lock the front brakes only but foot braking just enough to hold the front brakes will work also. When the brakes are dragging on the rear they can heat up during a burnout and you risk getting brake fade. Holding the brakes enough to hold the car you start off in first gear then quickly shift to second. You want wheel speed to get the slicks hot. After a couple of seconds you let go of the brakes and start to roll out of the water box. Before the rpms start to come down or the tires grab drive pavement, the tranny has to be in third gear.

Doing a burnout isn't hard on the engine unless you red line it. Doing a burnout can be very hard on transmissions. You need to be out of second gear because that's the weak link in the tranny. If the wheels are spinning and suddenly stop when they hit drive pavement, you can disintegrate the intermediate sprag inside the transmission and lose second gear.

Doing a burnout with a manual transmission is usually in second or third gear. You want a higher gear to get wheel speed and it's hard to shift a manual transmission while doing a burnout. Since the tires need to be wet, it's easier to get them spinning in a higher gear.

Using street tires at the track you want to avoid the water whenever possible. The tread will pick up water and drip it down on the track making traction poor. Drive around the water if possible then do a dry hop spinning the tires slightly just to clean them off.

I use a 2 speed powerglide. I start my burnout in first the quickly shift to high. I hold the rpms around 5000 rpm for a few seconds until I see smoke at the rear. I'm guessing wheel speed is around 100 mph in the burnout box.

 

Just like Stephen said. But if you got street tires....go around the water. Do a quick throttle to get the tires spinning a quick one to get small crap off the tire and line er up. thats it.

 

can u explain a throttle and a dry hop spinning?

i have an idea..but unsure.

 

You can do it from a dead stop or rolling slightly. Slight brake pressure might be needed. Mash the throttle quickly then let off. If you have enough torque to spin the tires, that's all you really need to clean them off. If there's water in the tread because there's not enough room to drive around the water box then a dry hop may throw most of it out of the grooves. You might want to do one more before reaching the starting line depending on how much room is between the water box and the starting line.

Putting it in neutral and reving it a few times to "clean the engine" isn't needed on an EFI car. Most carbed cars don't need to do it either. I'll do it every now and then if I load the engine up too much during a burnout.

 

Spin the tires and pull up to the lights.I would suggest that dry hops look cool, but defeat the purpose.The burn out is for cleaning the tires and getting them heated up evenly. Dry hops can possibly put a flat spot on the tire causing you to spin.

mash the throttle...same as press all the way down real fast on the accelerator pedal?

any specific gear should u be in? ive got a automatic

 

u can still do it with out wetting ur tires but its easier and more smoke if u do it if the tires are wetter

 

drag radials are an exception here...you probably shouldnt use the waterbox because they still have treads that kick water around but at the same time you NEED to heat them really welll for them to hook....i personally use the waterbox on my nittos and have never had a problem with dripping water on the track (the guys behind me hook fine)....also i kind of have to use the waterbox because you cant drive around it at my local track...if your on real street tires avoid it at all costs...hot burnouts make street radials greasy and slippery....i usually inch through the water and stab the throttle for a split second while in the water just to spin the tires once and coat them in water. then i roll a few inches past the water box, stop and burn the tires through 3 gears ending in third, while seeing smoke in my mirrors for a count of 5 seconds, then i let off the brake and ride the burnout up to the lights because i dont like just stopping the tires without the car moving...seems hard on parts...

 

a lot of people do that.....i dont understand why exactly...
