First of all, for all of you stick drivers, how exactly do you spin the tires (burn out). What exactly do you do with the clutch??

I am not a newbie stick driver but....

WHenever I try to burn out (in a straight line) I bring the revs to about 3000k/min and let the clutch out at medium speed and in the middle of the engagement point I floor it and let the clutch out.

THe revs climb to about 5k and stay there for a couple of seconds and the car doesnt move (doesnt seem like the tires are moving) and then after that I lose grip. Then of cource I get the wonderful burning clutch smell....

I thought that went the clutch is fully out that the wheels would break lose right away.... It doesnt seem like the clutch is fully engaged or something weird that that.

What gives? It seems like the clutch burns during that 1 or 2 second delay.

Also, what is the best way to not hurt your clutch and burn rubber?
Any way to check your clutch life?
How much would you have to f up to totally blow your clutch?
Any comments appreciated..... keep in mind my car has about 4200 miles now (if that matters at all).

could it be traction control thats stopping you?

what you described sounds like a slipping clutch but your miles are too low

and in the first 500 miles you shouldnt take the RPM's past 4 grand to break in the clutch, did you follow that rule?

Traction control was off, and yes, the break in procedure was carefully adhered to. The clutch seems fine becuase if I put it in 5th gear at 30mph and floor it, no slippage occurs.

Any ideas?

Maybe if someone posts how they successfully burn out with detailed steps I could try it??? Thanks.

rev it up to 4.5k and just dump the clutch hard. my 325 will break the 245 tires loose. your 330 should do the same.

i wouldnt advise doing this (espically doing it often). that tranny, driveline, and rear end arent very beefy and that kind of abuse will eventually break something.

thats why i do brakestands in my tahoe. hahaha!

Well, as far as I know, you want to dump the clutch, not let it out "at a medium pace":evil2

Just rev it, then dump the clutch. I'm not sure, but I think some models have a valve that only lets the hydraulic clutch out at a certain speed, so you may be running into this as well... :dunno

My 6 has a hydrolic clutch.... you still can breakem loose tho.

I'd suggest trying and practicing on a less exspensive car if you or one of your friends have one...much better than having to fix the 330..

I can easily break the tires loose dumping the clutch at 3k and up and break the tires looks through second gear. I just dont know why there is that pause before the tires spin. I have 265's in the back and maybe thats why??

"Just rev it, then dump the clutch. I'm not sure, but I think some models have a valve that only lets the hydraulic clutch out at a certain speed, so you may be running into this as well... "

I removed the clutch delay valve and I suggest that everyone who has a stick bimmer should do this. It makes the shifting alot smoother and less jumpy, and is much easier to drive without that valve. I will post pictures of what it looks like tomorrow. But is dumping the clutch the only effective way to break the tires loose? Does that burn the clutch at all?

depends on the tires. if you have 265s and good rubber it'll be hard but still ... you should be able to burn some rubber especially with a 330.

follow Serious's instructions and go try it again.

What the hell why are you letting it out at a "medium" pace. That's how you fucking burn your clutch and it sounds ike you've nearly ruined it.

Because I dont want to dump it, stall, or bog. I can break the tires loose easily by dumping the clutch but I want to find a way to not dump it and burn out.

Wow, I'm interested to see this! Any adverse effects under normal driving conditiions?

THere are absolutely no downsides to removing this if you know how to drive stick. Check out this link:

Is your clutch slipping?

WhatUp- please watch the language in the Main Forums. And if you want a good launch (without wheelspin) you release the clutch slowly...

Why do you want to do a burnout?

The best way I would think of, even with your oversized tires out back would be to rev it high, like 5500-6000 rpm, and let the clutch out quickly, and if you see the tach dip as it grabs, just floor the gas pedal down to keep it going...

hmm.. looks like I can handle this, but "bleeding the clutch circuit".. Pump the clutch rigorously a few times, or something else??

its the CDV i have the same problem especialy when i slam 1st to secont i get slippage cuz it prevents u from "dumping the clutch"
if i understand this correctly.

That sounds a bit funny coming from somone asking for advice on how to do a burnout. :awink:

Driving stick "properly" does not include perfect execution of burnouts. I can launch and shift real well, I just dont want to dump the clutch to burn out. As far as removing the CDV, I would have a shop do it because you need to people to bleed the clutch circuit correctly. But I have to tell you, taking the CDV out is THE BEST thing I have done with to the car. It is so much more fun to drive, easier to start out and get up hills, and it is 100% smoother. I can safely say that BMW was stupid to put that piece of crap into our cars.
