for those who do, what is your method? Pressure? RPM? Slip, or dump?

 

5500 rpm and dump it. Only because I have a stock clutch and I can't dump it any higher on the stock clutch. If I had an aftermarket one I would be dumping it from 7200.

 

Neal, what's your technique for warming up the slicks? Go through the water stuff, then pop the clutch? Do you pull up the e brake? Do you get any wheelspin with a 5500 dump?

 

So..... the slicks won't slip at all? Even at that high of rpm?

 

E-brake is a must. You need to do a quick spin in the water to get the water all over the slicks. Then pull through and spin them and shift into 2nd and hold it for a few seconds. If you do this enough times you will know when they are ready bceause the feel of the burnout will change and the car will start pulling forward. Slicks should not let go at the top, or really ever. Once I got my technique for the burn out figured out they would hold on my launches with nitrous with 430whp!

 

well I got a great deal on a pair of M&H's. 3/4 tread still left on them for $50
Anyone else running these?

 

My slicks are M&H. M&Hs like to be hot. the hotter the better. like mardigras said i do my burnouts in 2nd gear. they way i know my burnout is just about done is when i can smell the rubber. as soon as i can smell the rubber and see the smoke filling my interior i let off the ebrake and start moving forward. on my way up to the lights i tach it back up to about 5k and drop it really fast to make sure they are sticking. then i go up to the line and tach it up for my launch.

 

what tire pressure are you running?

 

I think I was running ~12psi

 

Your tire pressure will never be the same two times at the track. Well it might but it wont always be the same. I start around 15-16psi and work my way down in 1psi increments run after run usually ending up around 12psi when my launches feel "right." I tried 10psi once but I lost like 2mph and didn't get out any harder. I ran them once at like 26psi too oops, it was the first run of last year and I had forgotten to let some air out. I had like a 2.44 60' hehe. Slicks are just trial and error basically.

 

Ok, I'm really slow, so let me see if I got this whole thing right....
1. Go in water and do a quick spin w/o e brake.
2. Get out of the water, pull up e brake.
3. Pop clutch, spin through 1st, shift to 2nd. (How long does the entire burnout take?)
4. Go to the line and pop clutch at 5500+.

So some questions now....with all the torque having to go to the ground with slicks, what precautions are you taking to ensure you don't break anything? I am interested in running a medium shot of nitrous at some point, and I'm wondering if any part of the procedure is different. Let's say I don't have the nirtous spraying out of the hole, and I have it turn off 500 rpm before redline...how much extra strain am I putting on the driveline compared to running NA with slicks?

 

I don't think mardigras launches as hard as I do, we cut about the same 60' times but he's putting down alot more power, so he is likely much more careful than I am about my clutch dumps. I take no precautions. I worry that I will break and just hope I don't.

His burnout method is different than mine. I do my burnout in the water and then as the tires are starting to get hot I let off the ebrake and continue the burnout until it pulls me clear of the water. Then I roll forward a few feet and tach it up again and do a quick launch to make sure they are gripping and not still wet. Then I go up to the line and get ready to race.


Also, while I'm still in the water I turn the wheel side to side so as to get the entire surface of the slick warmed up.

 

How long does a set of slick last...considering the abuse they see...

 

Damn near forever as far as I can see. I have probably 75-100 passes on mine and I'd say the wear indicators are at least 2/3 of what they originally were.

If you think about it, they really don't take that much abuse. The most of the time they are spinning they are doing so on a sheet of water. And they don't spin on launch either so there's not much wear there. They just kindof roll around everywhere and don't really see much wear.

 

Man, i have a set of slicks available to me to use for our track day coming up, but im getting more and more weary of using them. I really dont want to break anything. But damn, launching at 5000rpm, and for me, spraying out the hole, would realllllly put a strain on my tranny/axles.

But wouldn't it be fun!

Thanks for the info Neal.

 

well my slicks are mounted.
a 9 inch wide slick kinda looks funny on a 6.5" wheel
Also these are 24" will this work out in my favor?

 

Can't answer that without knowing what your mods are.

 

allow me neal his mods are : MEVI, udp, NX wet 75shot, act street clutch, ypipe, CAI ..did i miss anything ?

hi dave ...i was keeping an eye on ur post

 

yeah that is pretty much it. It is Neal's car without weight reduction, ECU and catback. Add Nitrous of course.
BTW thank God the org is back, I was going into DT's
