The way I see it launching in general damages the
car no matter what.. my question is what causes more
damage- dumping the clutch which may brake\damage the gear box or pulling out the clutch slowly which may burn the clutch..

i'd love to ear your opinion

 

Clutch is cheaper than gearbox.

 

I would rather let the clutch get it than a spline gear or something in that nature

 

The evo clutch needs to be dumped. Slipping it out slowly will burn it fast.

 

What about Lancers?

Cheers

 

...not having stick ... i dont have these problems, but i do not alot of people who dump there clutches and then they have problems with them a little later on.

 

slipping it ruins it hella fast.... just ask my 40k car sitting in the driveway

 

Are you driving a stick or Automatic. Pm me if you need details.

WARNING/Disclaimer:
Dumping the clutch is better on the clutch but can be bad for your drivetrain. This damage factor depends on how you dump the clutch, throttle, RPM at which the clutch is droped, drivetrain style(AWR/RWD/FWD), HP, torque, clutch strengh, Number of times you do race style launches.

Keep in mind that launching with an AWD car hurts the drive train and clutch more than launching with RWD or FWD because the tires will spin easily on RWD or FWD. On AWD the clutch is more likely to slip and burn.

Me and this guy speak from experience. You can lose a clutch in 1 bad slip. I do not know who is spreading this slip the clutch crap. Most Noobs cannot slip properly causing one to burn a clutch. Most Noobs do not drop with the fury of a racer which is why I reccomend the drop over the slip.

Another reason I reccomend the drop is because on stock parts the drivetrain can handle drops. Which is why I mentioned The damage factor is related to how you drive and how much power you have + what power your drivetrain can handle.

 

does your clutch burn everytime you guys launch ? even if i launch at 3,000 rpms i smell that horrible smell

 

I can slip at 4k until it builds boost then dump and I get no smell so I feel that a combo of good driving you can acheave both on the stock clutch.

 

My best autocross launches have been by dumping the clutch in the 5-6k range. I get just a touch of wheelspin and off I go. When I've tried to take it easy by using fewer revs or slipping it more, I feel like I'm hurting the car, dumping at 5k and nailing the throttle just feels like it is easier on the car.

I've never been to the drag strip though and I suspect that is probably different because you probably have a harder time getting wheelspin with all the rubber that's already laid down there. Dumping it there could be rough on things if you don't get any wheelspin.

Between the restrictor valve and 2' rubber hose in the clutch line, I think has given us a nice automatic launch control (for you F1 fans ) -- it gives you just about the right amount of slip when you dump the clutch, at least in a relatively low grip situation like at an autocross. If you've removed the valve and replaced the rubber hose with ss, then I think dumping is going to be too rough on the rest of the drivetrain. But you will have a better feel for how the clutch is actually engaging and that may be just what you need at the strip...

I think it all comes down to experience, I have seen both lauches achieve close to the same time but dumping will always be a little faster and slipping will be safer. On a high hp car and tons of grip with no slip eventually you will damage somthing. Bottom line is just have a clutch fund in the bank or don't do it.


I guess it just depends on how do rate yourself, a little safer or faster?

 

bottom line is dont let it slip for like 5 minutes. If you keep the clutch just slightly depressed you're gonna burn it like hell. Oh and slipping is definately better in the rain and other low traction situations...Yah first time i drove in the rain i came out of my neighborhood dumped it on accident(my foot slipped, dont wear loose sandals...) and slid out across 2 lanes...good thing it was at like 11pm

 

I use a slip/drop method. I want to disclaim that my car is not stock... What I do is rev to about 5500-6000, let the clutch slip slightly, then drop. It's not nearly as harsh as just dropping the clutch... I would also like to add that I have been through one clutch, and one transfer case already. I have a SS clutch line, without I dont know how any of you guys can tell when the clutch is engaging. As soon as I put the SS line in, it was night and day. My .02
