hey, i was asking inthe 5th gen forum on how to do a burnout with an automatic that is going to have drag radials on it. can you give me a step by step guide or something? ive driven rwd cars, and can burn those out easy... but im not too sure on fwd. i dont want to ruin my buddy's car when i go to stage.

also, will he need any other mods for his zex 100 dry shot kit? i mean, we are trying to stay low budget here...

With dry setup get a walbro pump, probably a 255 high pressure. To do a burnout, drive into the water, then pull up on your hand brake, brake torque the auto to ask much as you can and then let go off brake and floor the gas and burn baby burn. But I am 5 speed so all I would need to do is pull hand brake and slip clutch at 4-5k rpm and smoke here I come. But I never do burnouts.

why does he need a fuel pump? zex says that he should be able to run it on stock pump and injectors

You can run a dry shot on stock injectors, its how BIG a dry shot that is the question.

Zex iirc only supplies jets up to a 65 or 75 HP not 100, and that is what it will probably do safely.

The problem with a dry setup and fuel is that the higher the shot the higher the fuel pressure that is required because the extra fuel is put through the injectors via the boosted pressure.

The higher the pressure the lower the volume so at some point the pump will not give you the required pressure/volume and that is generally considered to be in the 75 HP area.

If you have a fuel pressure gauge all I can suggest is try it but keep a close eye on the pressure because if you can't keep it up its going to go kaboom.

PS Doing a burnout in an auto is even easier than a manual. You just pull the ebrake and hit the throttle. Many tracks will not allow you in the water box unless you have slicks so you may have to do it dry.

do it dry. with drag radials you have grooves that will retain the water
and puddle up under the car when you stop. in some cases the guy flagging you will ask you to get to the back of the line until you dry. with slicks there is no grooves to catch the water. just do it dry at your first staging area.

With all the tracks I've been to all across the nation, they allow you to burnout on any tires. Personally, I would never recommend heating up stock street tires b/c of the fact that it doesn't help and it gets water in the tread.

But, as for a drag radial, they MUST be heated up to get their full potential. Their compound is meant to be heated up like slicks. That's how BFG can claim to get those insane 60 foots on the DRs.

But when i first got my DRs, I would still chirping them off the line. I was only getting 2.21-2.23 60 foots with a slight chirp or two.

Then, I tried to do my first burnout ever.... failed. Tried again... failed. Finally, on my third try, I got enough water on my tires, held the ebrake and stalled it up and floored it. I had it in 1st gear so it wouldn't shift (which is bad.. I'll explain later). I did a burnout for about 2 seconds and it stopped spinning by itself and pulled me out of the water box. I launch without a single chirp and cut my best 60 foot of 2.17.

A couple weeks later, I am racing at a different track and needed to do a burnout. So I rolled through the water box, spun the tires while in 1st gear and it spun for a good 2 or 3 seconds and bounced off the 1st gear rev limiter. I stage and launched the car and I was stuck in 3rd gear (fail safe mode). I believe fail safe mode exists in 3rd and 4th gen Maximas.

But, after a couple track visits, i found out the right way to do a burnout in an automatic. Put the shifter in 2nd gear or D. Do your burnout and instead of holding it in 1st gear and hitting the rev limiter, allow it to shift and keep it in 2nd gear and you can burnout for as long as you want.

But keep in mind, 2 or 3 seconds is all you need in a burnout. So sometimes it will shift into 2nd gear and sometimes it won't. There is no need to burnout anything longer than 3 seconds.

Canada must be different than in the US. All of our tracks allow you to burnout, no problem, its the water box they won't let you into unless you have slicks.

Yeah. I've been at several tracks in North Carolina, Vegas, and only two in SoCal. 3 of those are NHRA sanctioned and they don't care if you go through the water box on street tires. I see ricers do it all the time. It ****es me off.

here at racewaypark in englishtown nj they will announce on the loudspeaker(no burnouts in the water unless you have slicks) or you will be sent to the back of the line but for drag radials you can burnout as long as its not in the water.

I wouldn't doubt it. It's a good rule. Different tracks have different rules, usually in conjuction with NHRA regulations. One track I go to in Cali requires that everybody have a helmet reguardless if you're running 19s or 9s. I think that's a good rule.

But if I wasn't able to get in the water with my drag radials, then I wouldn't come close to doing a burnout without doing a 5K N drop. lol

ive been to carolina dragway, and silver dollar and both those places let you go through the water, burnout on street tires(i didnt) or whatever. i think carolina is IHRA sanctioned, and im not sure about silver dollar. its stupid to go through the water anyways if you arent going to burn out

thanks for the tip on how to do a good burnout. i think my friend is trying to get rid of his max for either an 03 cobra or mach 1.
