I have always wondered why the slick guys complain about the street tire guys driving through the water. They say the street tires bring water up to the starting line. Maybe with the fronts but wheel speed and heat should get rid of the rear tire water.
What about the front tires of slick cars? They drag water up to the line.
I try to drive around the water and back into it.
Sprays it on the wheel well and into the wheel lip. Then it drips down as you drive up to and sit on the line.

Blipping the throttle is needed at some tracks.
which tracks, I dont understand why its needed anywhere, pull into the water, pull out of the water. where you do your burnout is the same no matter if you blip the throttle or not.
i pull in the water, and stop where mike tells me to stop, put into nuetral, pump the hell out of the brakes (got a bruise on the back of my left leg last race), set the line lock, pull it into 3rd gear, wait for mike... floor it, watch mike... let go of the button and drive it out til i feel the rear wheels chatter, lift and roll to the starting line.
if i dont get on it hard at the initial hit, it will slide to the side in the water.
dont blip the throttle, it doesnt do anything positive/beneficial for the run.

Leon's description of proper burnout is pretty much spot on with mine. I roll past the water, start in second gear,hammer the throttle hard enough to get within a few hundred rpm of shift point, go to high almost instantly. I only hold the line lock on for about two seconds. I allow the car to move forward during the burnout so as I ease off the throttle traction is starting to pull the motor down. I wind up within about five feet of being staged this way.

I'm not relying on Mike or anyone at the water box to determine my tire prep. Each time I pull to any water box there is a decision. How much water is in the hole? How long is the wet spot? Did a dragster just spin water 20' towards the line? Adjust accordingly. Roll thru. Or blip then roll.
mikes the car owner (Mr. PBody), not the water box guy... i wasnt clear on that, sorry, but again I ask, why blip it, what track do you run at that its needed to do that at, like you said?
I'm not cutting down the fact that you do it, its your procesure regardless what I think about it, (or others on this board), but only am wondering about a comment you made that its required at some tracks.
of course there are things to take into consideration, but if there is too much water in the box then you have someone sweep some of it out, if theres not enough you have them put some down, if the dragster spun water up to the line, then you have your crew person direct you so youre not rolling through that mess instead you straddle it. if you have a good crew member all you need to do is the burn out and not need to be concerned with all that other stuff.

Easy, in high gear, roll through the water, when the slicks are about 6 feet past the waterbox, nail it and keep the rpm's up just below the chip, roll off the throttle a the 300 ft. mark, you'll roll out to just about the 1/8 mi. mark, put her in reverse, back up to 6 ft. behind the starting line, put it in low, roll up stage and be ready to go.

Blipping the throttle is needed at some tracks. A 32" tire that's over 8 feet of rollout, some tracks might only have a couple of feet down.
I think he only has a 28" tire. The tire will push a puddle of water ahead of it. Plenty of water on the tire.
Pull up ahead of water LIne lock second gear Stand on it When the engine rips put it in high If running a rev limiter on the line lock pump the button to release the line lock but keep the rev limiter working and when you feel the car start to lunge back out of the throttle. Pull on up and turn the top buld on and wait on the goof that can't figure out how to stage.
Thanks Leon, I never thought about the tire pushing water ahead of it, but I have seen the result, so I agree.
When I am helping another racer, I make sure there is not excessive water in the water box, but spray a light coat behind the water box so the tire can just role through it. I wish I had a crew to make sure that was done, but most of us don't and the track workers vary a bunch...
Just note, "only a 28" tire" still has 88" or 7ft-4" of rollout.

Slingshot383...thanks for the advice but I think I'll pass on the promod burnout technique. It might be a little overkill for my ride.
I will definately be going with no blip, 2nd to 3rd gear burnout technique the next time out.
Someone mentioned a while back that bad clutches in the sure-grip could be to blame. Is there a way to check this to make sure they are ok? I have a spare set laying around that I could put in it but don't want to waste them if I don't need them.

uneven coming pout of the box can mean a sign of preload also

I am running 1/3 turn more preload on the right side vs. the left side with my Caltracs.

I think that alot of this depends on the tire, track prep, power levels etc. With most tires these days you don't have to heat them like 20yrs ago...clean and haze alittle regardless of your tranny setups.

No solid answer here, but a couple of ideas. You got the no blippy of the throttle thing down, thats good. Your car is no doubt kicking left,IMO Getting to a faster tire speed quicker will help that. Also it appears that you are trying to Steer into the slide. Thats a learned tendacy in a slide situation. But, with a burnout, if you steer into the slide you help promote it and make it easier for the rear to slide in that direction. Hopefully a simple fix will be, is to get your wheel speed up quicker and quit steering into the direction of the slide. If you put slight steer input against it, you may be able to stop it. If not you may have a Preload problem or a axel thats not square causing it to dog track abit. Now it could be the camera optics, but even appears down track the cars rear is pulling to the left and pushing the front to the right by just a bit. It does launch straight though. And your car, looks awesome mike
