So after doing something I shouldn't have done in the 1st place. My clutch is slipping everytime I take off from a stop, but just barely noticable IMO.

I did that "clutch slipping test" where you put the car in top gear and mash the gas pedal around 30-40MPH to see if the RPM needle shoots up. So the needle stayed fine and didn't notice it once that it jumped erractically.

Is the slipping probably going to get worse? Is the clutch toast? Should I just goto a shop and get everything fixed?

Help would be appreciated. Thanks.

 

is it slipping or shuddering. My clutch has shuddered when it's cold outside since day 1. Will it only do it for the first dozen or so starts from a dead stop or is it an all the time thing?

 

From my understanding for searching about "clutch slipping" it's happening everytime from a dead stop and only from a dead stop.

It's been doing ever since I did a bad launch.

 

I am not sure how you guys launch, but if you do it right, you shouldn't have any problems except worn tires.

The proven method to net 1.6X 60' times or less. Launch in Boost (between 5 ~ 6k rpm), coupled with a quick slip drop!
If you do this right, all the wheels will spin and you'll bolt!
Something has gotta give, First Gear, Clutch or the Tires. And you would rather the latter then the former.

You either launch or you don't launch!

Been driving the AWD vehicles since 2002, (but hats off to those who been driving since the day it was born), so I've been through most of the do's and don't's

We've also proven this method on our WRX's and STi's (wrx has a weaker gearbox but that doesn't matter if done right). Taking it all apart, it still looked and functioned new after 100 launches (except the tires)!

 

Robert, the clutch can't slip in 1st gear if it doesn't slip in high gear at peak torque. That doesn't make sense.

 

Well this is the same ? I asked a couple days ago in the Evo engine forum. I wanted to know also, if sometimes clutches just slip occasionally. In my experience once it starts it just gets worse.

 

Ok sorry if I phrased that wrong. I read somewhere that its noticable everytime one takes off from a stop. This is happening to me.

It doesn;t occur at any other time

 

When my clutch slipped it was just as Warrtalon describes. Never happened in first gear. It always happened in like 3rd or 4th gear when I'm already rolling. I'd put my foot to the floor and watch the RPM's shoot up and come back down. Not fun.

 

Here is where I got my info from Warr.

"Clutch slipping is most obvious when you are just starting out from a dead stop or upon sudden acceleration in a low gear."

This is not happening to me though... tried it atleast 5 times this morning on the way to work.

 

Maybe that's true on other cars, but it's not true on the Evo.

Our clutch is most prone to slipping when we hit peak boost in higher gears where there is more load. We have a sudden, violent onset of boost, and in high gear at low rpm, that is a TON of torque. Just look at any dynograph, and you will see. It's torque that causes the slipping, so if you can roll into boost in 5th gear from 2500 rpm without it slipping at all, then your clutch is not slipping. I don't know what is happening to you in 1st gear.

 

If your clutch is ineed slipping, and the only time you're feeling it is from a dead stop, then it WILL get worse. Mine started from a slight RPM raise to a big one.

Edit" but I don't think I've ever felt my clutch slip in 1st gear from a stop.

 

I found this information on another forum. I wonder if this is happening to me..

 

I don't know...maybe...but I warped my stock flywheel when I still had the stock clutch, and I still never slipped in first. Hell, just before my clutch totally went out, I cut a 1.73 60' and ran a 12.24 back when I just had a cat-back, mbc, and SAFC. We launch at high RPM where there is much less torque than at low rpm and much less load than in higher gears. The warped/mirrored flywheel, damaged disk, and mirrored pressure plate still only slipped when there was enough load under boost in higher gears - not in 1st gear.

Also, right now, my ACT is on its last leg and slips in gears 3-6 noticably then sorta slips in 2nd (hard to tell). There is no slippage in 1st - it still rockets out like a cannon.

 

my clutch is out i cant get boost in fourth or fifth without slipping, but i can hammer it all day long in first with no slipping
