Finally got my hoosier dr2's on and want to get a little practice in before I make an *** of myself at the track. It's a head, cam z on stock clutch for now but it seems pretty strong so far. My burnouts in preparation for a launch are horrible. Any pointers?

Be careful

I snapped my half shafts doing that ! 😂

At the track or on the street?

Most beginners don't bring the rpms high enough and fail to dump the clutch quick enough and get right on the brakes.
It takes some practice and trust.

I'd stop the car in the edge of the water box where it's damp and rev the car to around 5000 rpms. Then completely dump the clutch and get on the brakes asap.
Try and keep light pressure on the brakes after the initial hit of the pedal. After the initial hit the rpms will start bogging down so you must keep adding throttle to prevent stalling and or creeping forward. There's a balance to achieve and practice is the only way. Safety always comes first so bail out and hit the brakes and push the clutch in if things start to go wrong.
And make sure traction control is off.
Lastly, you should practice at a drag strip and not care what it looks like. Everyone has to start somewhere.

you spent a lot of money on the car and some mods - now spend a little more and buy Line-Loc..............blows me away why so many need to do the brake method.

Quick question, sorry to threadjack:

Tried doing a burnout in my c6z the other day. Traction control was off. As soon as the wheels started spinning and I got on the brakes the engine loaded up and went back to idle and the DIC flashed "active handling". According to the owners manual, when traction control is off, you have complete control over rear wheel spin. What gives?

I strongly recommend getting a line-lock installed. Easy, and inexpensive.

Few hints:

Drive around the water box
-The front tires will carry water into the surface which is two folds safety and further hurt your traction.

Back-up into the water box
-Get lined up with the track, back up into the box, and get one revolution of the tire in the box.

Drive out the box
-DO NOT DO A BURN OUT INSIDE THE WATER BOX, drive out, about 3-5 feet and do your burn-out.

The burn-out
-With a line-lock, once outside the water box and with clearance from the track safety team depress your brake pedal and hold, engage "lock" your line-lock switch, release the brake pedal (to free your rear brakes), bring your RPMs up-into 4-5000 RPMs, release the clutch in a fast but controlled movement, dont just drop the clutch -RELEASE THE CLUTCH COMPLETELY, do not ride it- do a 2-3 second burn, unlock the line-lock, and while holding the tire spin, roll forward, easing on the gas, depressing the clutch, come to a halt.

Stage
-Since I assume this is test & tune, do not deep stage. I recommend shallow stating to maximize MPH and ET. For shallow staging roll forward until the top staging light lit's, then slowly roll forward until the 2nd light barely is triggered on. Now you are shallow staged. Up your RPMs to o/a 3500-3800, and aggressively launch the car while controlling your clutch release. Its a fine line of clutch slip and full throttle engagement.

If you dont have a line lock. Then, I recommend "heel-toe" the Gas/Brake pedals, and releasing the clutch. I do not like the drop the clutch, jump on the brake. Its dangerous and borderline reckless. Vehicle will in most cased turn sideways, I seen individuals hit the wall right by the water box doing so as well.

Good luck!!! Keep us posted!

This is one reason I have not taken my car to the track. Scared to death of having a wreck, plus not wanting to make an idiot out of myself. Good luck and let us know how it turned out.

way safer to do this on the street and your insurance will cover you if you screw up

That THAT comes from someone who knows how to run a car at the drag strip.

southspeed

anybody got a link to a line lock I should get and how hard is the install? something I could do myself?

Tech

This one looks high quality.

You have lots of other options though.

robz

Wow.
You've seen several people hit the wall doing this method??
And you have confirmed this reckless technique with those individuals was employed?
And vehicles in MOST cases will go sideways??
This stuff makes it so hard to help people.

And this stuff makes it impossible to help people.

robz,

Take it for what is worth brother. There are two ways of doing things.

The easy way and the hard way.

Chit happens, some times you get away with it, and some times you dont.

When you dump the clutch at XXXX RPMs, and suddenly jump on the brakes, the vehicle will unload the rear of the car, take him off track on a front-rear relationship, in some cases, way off.

The line-lock is not a "must-have", I just do not recommend the drop clutch-slam on brakes method. I must rather heel-toe brake/gas, since it allows for much more control when the line-lock is not available.

Tech

The hard way sounds like installing a line lock, TBH. Jabbing the brake is a pretty common thing for people who don't track their car regularly.

robz

I just want to add:
It will take practice. Ideally you should have a line lock installed in a place that is comfortable for you to engage.
If you are an absolute beginner it's best to bring a friend with experience who can talk you through the burnout. It should not be dangerous if you're calm. The track is the best place to learn. A track rental day is ideal. Forget what the spectators think. If you feel uncomfortable then stop the car, park it, and talk it through with someone who has experience with teaching beginners. A little anxiety is normal, but if your heart is pounding and you're sweating profusely, then you need to take a minute and relax.

If you have dry tires and/or completely dry pavement underneath them it will be harder to break traction and the car will want to grip MORE and move MORE.
If you do not dump the clutch, with or without a linelock, the car will want to move MORE and or bog the motor down quicker.
Maintaining rpm is the key to doing a proper burnout.

Thanks guys. Tons of help in this thread and a lot to think about. I guess I should go to an empty lot with a jug of water and do a little practicing.

mtomlin1

Here's one of mine

Just drop the clutch dab the brake hold it and then release be sure to not let it get out of

southspeed

^^^that is awesome!!
