How do you prevent going sideways when doing a burnout? It has been an issue for me. Thanks, Joel

I think you can fix that with either tire diameter, make sure both tires are within 1/4 inch circumference of each other, or in the posi unit.

How much wheel speed is required?

Worn track surface will do that. Wonky corner weights and different size tires will as well.
If the results don't match the theory, change the theory.

More wheelspeed plain and simple..If it launches and drives straight after the launch then it clearly is not a brake, chassis or tire thing. Since you say its a burnout thing I assume only when which means you need more wheelspeed. HIgh gear and how much depends on the car but enough for it to go straight is the answer

It's a manual transmission car. I've been doing a burnout in second. When I have attempted it in third a couple times it has slipped the clutch or been right on the verge of slipping. I'm getting rid of the soft lock clutch. That should make 3rd gear burnouts no problem

What gear and what type tire?
What rpm are you holding it at during the burnout?

As already mentioned, wheel speed. And a quick snap of the throttle. I snap the tires in 2nd and immediately go to 3rd gear. Car never moves, stays perfectly straight. And a line-lock makes the whole thing much easier and quicker. My Duster street car had 3.23 gears and no line-lock, I only had 5 passes on the car before selling it last Fall but that combo was causing me to go a little sideways also, I had to get real aggressive with the throttle to make it go straight. Making sure the tires are wet helps also of course.

I press the brake pretty hard and set the line lock. Dump the clutch at 5000, try to hold it at around 5500-6000. 4.57 rear, 1.78 2nd, 1.30 3rd, Rear tires are MT ET Street, LT 30 x 13.5-15, Bias-Ply, front are 6.70-15 bias ply. Straight front axle, wilwood discs, 4 link rear, afco coil overs on all 4 corners.
So in 2nd gear 5500 rpm is 60 mph. 3rd gear at 6000 would be 90 mph

The faster you spin the tires the sooner they will get hot enough to smoke, correct? I use to do all my burn outs in my old Hemi stick shift car in 3rd gear per some other SO CA Mopar factory back racers advice back a long time ago.

I'm getting rid of the soft lock clutch. That should make 3rd gear burnouts no problem I do my burnout in 2nd with 4.10's and 28 inch tires, only starts to kick to the left when tires start to grab. Does your car go sideways instantly or after some smoke? maybe the tires are ready sooner than you think. Soft Lock clutches seem to be preferred among many stick car guys, Takes allot of shock out of the system, I would think twice before getting rid of it. What clutch do you plan on switching to?

You can aggravate the car going sideways by steering into it as if you were drifting. It's a natural reaction but if its going sideways while not moving forward during the burnout try holding the wheel straight.

Since it was asked how much wheelspeed is enough, my answer would be however much it takes to straighten it up. I know manual trans cars have a bit of an issue as you have to get it rolling and not kill the clutch. FWIW my current car the burnouts are 6-6500, in high gear I use a limiter to get going at 5900, once it blips that I let it rip. In this car in high gear 6500 is probably 130+ mph. Have to look at the racepak to see where that is?

Just for sake of conversation, we all have to do what al is talking about sometimes, or cruddy burnout boxes, out of level areas, you name it. Just blip it up quick, and high. Personally, I like the car to go straight on the burnout whether I'm barley spinning, or near on fire. Spinning super fast just vulcanizes the center of the tire, and if the situation means that's all you can do, you do it. Setting the car up to go straight on the run, then adjusting the front springs till the car will burn straight no matter what RPM is a better way IMO since you can let the tire settle down and flatten out some. Just personal preference.
