Dumping the Clutch

what does the phrase mean "dumping the clutch"? and how do you do it?
I have an idea just would like to know for sure... and is it good for the car?

Well dumping the clutch is when you drop it from high rpms. The only thing that takes a beating is your clutch so it's not good for your clutch unless you got a proformance clutch.

Its letting the clutch engage very quickly withought realy stoping at it's catch point to let it slowly engage.

Taking your foot off the clutch peddle as fast as possible, gennerally a high RPM to spin your tires, with AWD cars this with do 1 of 3 things.
1. Make your car stall, or very close to it.
2. Make your car take off and throw you back in the seat.
3. Break something

Aim for result #2

I've been too much of a pussy to get anything but the first result, always thought I'd brake something if I let it out any higher, so I never got a good fast launch in my SL.

do not dump i am on my 3rd trany broke the t-case every time i do like kind of a dump i let it go till it start to engage and hold it till the rpm start to go up than let it out the rest of the way it worked the best for me

yeah, but the 6 speed transfer cases are much much stronger. However I dont not dump the clutch either, I get a better start by slipping the clutch opposed to dumping it.

ok wut does slipping the cluth mean?

it's the opposite of dumping, slowly letting go of the clutch...as long as your tires spin when you dump the clutch (and keep spinning) you won't hurt anything. But if you have good tires and not enough power to make them spin when you dump the clutch from say 7500 RPM's, somethings gotta give and will most likely break in doing so. If you want to do it that badly, wait till it rains or when you're on ice to practice.

i have a 6 speed and i still broke my t-case

so i guess some of us have had some bad luck dumping/slipping the clutch. i dumped the clutch on some 6000rpm launches a few times racing when i first got my car. since it had pretty crappy tires, i wore them down really fast. so ya, don't dump the clutch unless you don't care about your tires and don't mind shelling out some $$$$ to get new ones.

HEY! WHOA! an epiphany! if you wanted to just have some fun, get some slicks, or any tire with a LOT of tread, then go around dumping the clutch all you want...maybe practice some burnouts (if you have the power).

alright well how much does a t-case usually cost?

when i broke my 3 i hade to buy new trany to because the shaft broke of inside of it. my t-case and trany was a little over $4k but i have a 6 speed not the 5 speed that my car came with

Don't dump the clutch often, our clutches and t-cases suck...but it is my opinion that everyone who owns a vr4 should at least experience one 5k+ dump sometime in thier life.

hmm good thing you guys said something about this, because im just finishing converting my automatic over to manual and planned on treating it like it did my Integra (dumping all over whenever). Probably would have broken something and got pissed off and even more poor :(.

I dump the clutch in my FWD all the time. It has at least 50 track runs on it and who knows how many street runs. Still holding together without incindent.

And I know the guy that owns importpoweronline.com. For those of you from 3si you know who I am talking about. But Chris had a 92 VR4 and did 6500rpm clutch drops all the time at the track. He never broke anything but his engine. :lol: When he finally sold the car his last rebuild has 15k miles on and the 6 puck clutch with all those mods and it was still strong as an ox. The guy that bought it added a roll cage and front mount and was recently selling it on ebay because he was moving or something.

Well it's less wear and tear on any 2 wheel drive vehicle, because your tires are spinning. But on an all wheel drive vehicle your tires are gripping the ground, techniacally speaking "It hurts your baby"

:slap:

ok wut does slipping the cluth mean?
you can dump it with a front or rear drive car not all wheel drive you will brake shit .........def brake shit.slipping is a goodthing but it can glaze over a clutch.try not to do it back to back ,clutch will get to hot and slip.thats on all cars with a factory and even most after market clutches

Read my post. Chris(known as IPO) on other boards did many, many clutch dumps in his VR4 and never once hurt the drive train. His was a 18 spline too. If I remember correctly he has some kind of record for fastest time on street tires at like 11.3. Mainly because of his 1.6-1.7 60fts. Another friend of mine did many clutch dumps in his VR4 too until his clutch gave out. That was a stock clutch though.

Yeah, but for those 2 people who didn't break anything, I can literally name 20+ who did. I'm not saying that if you do it, you will break something...I've dumped my clutch from 5k+ around 8 times, no problems at all...but you are putting alot of pressure and power down, and it has alot of resistance with all the traction of AWD. Our stock drivetrain and clutch aren't all that beefy, and can give way...

I wasnt saying go out and do it all the time. Chris has had a lot of luck with his projects too and really knows how to drive the car. But thats what a lot of it comes down to is the driver. Look at Matt Monet at Dynamic Racing and everything he has done on stock drivetrain too.

Another thing about driver. Chris at importpoweronline has the worlds quickest FWD 3/s (something like 11.54 at 127 and even a 11.6 at 131). All he added to the transmission is a quaiffe lsd and he is pushing serious horsepower and running slicks. The car would most like be in the 10's if he didnt blow a ring land on his last run. A bunch of things added up to that breakage but all that was done a 158k mile stock NA short block. According to some calculators he used (car has never been to a dyno) he is pushing close to 500hp. People not running anywhere near the power he is break stuff all the time. Why is this? Who knows really.

I guess the point I am making is our drivetrain and other components arent as weak as some people think.

That may very well be the case, and there is no proof to prove either way. But with the known shortcomings of our clutchs, synchros, and transfer cases, let's just say my faith isn't 100% in Mitsu's ability to build a rock solid drivetrain, and I'd rather be safer than sorrier. Just my opinion...
