So I was practicing launches on my stock clutch I did get my evo 9 mr tuned to 22psi and after I was done the next day when I was driving I noticed that the clutch would engage then go up 1000 RPM and then go back down while driving in gear does this mean i need a new clutch or can i do something to this clutch to make it engage better until i get a new clutch. and if i do get a new clutch should i also replace the flywheel or just get the one i have resurfaced.

 

Do you have your clutch pill removed?

Its entirely dependent on what your flywheel looks like. I would suggest having it resurfaced, but it depends on if you're switching to a different type of clutch or going with the stocker again.

Sometimes if you get the clutch really hot, it will glaze... it may have just glazed, but I'd suggest taking it easy on it and seeing how that goes.

 

You have probably put a fair few hot spots on your flywheel if you were launching for a long period of time. Just do what ProPilot said and take it easy for a while. It should come good.

 

If you want to see if its slipping get into 3rd or 4th gear at a low rpm and give it decent throttle and if its slipping it will jump pretty fast but will not put power to the ground

 

Why not just do it stationary? 1st gear, handbrake on - but pull up as hard as you can and try and get the car to move. Plenty of throttle and use the clutch to bring down the rpm as low as you can.

 

Um im pretty sure that would just burn up whatever is left of the clutch.

 

Well then it's time to replace it if its slipping...

 

No. Stop.

Try to undertand how your vehicle works, before you gak it all up.

1. There is no reason to "try and see" if your clutch is slipping so that its time to replace it. Its either slipping and you replace it, or its not and you don't, or its not and you replace it.

If you want to replace it, replace it. But don't come on here asking for help to figure out if your clutch is slipping if you're just going to replace it anyway.

2. When you apply the handbrake on your fancy AWD vehicle, this is like... the jacka** version of putting a load on the car. If you (for some unknown reason) need to find out if your clutch is in fact incapable of holding under the worst case scenario, then put the car into 3rd or 4th at low RPM and give it some gas. If its slipping, you'll feel it. But be advised... this is a good way to blow a hole in the side of your motor.

3. Applying the handbrake and using the gas is generally a bad idea in an AWD car. In ours for example, it "disconnects" the center differential so that the computer doesn't try to undo what you're trying to do. Its just wrong for so many reasons.

4. If your clutch isn't slipping under "normal" driving for you, then it isn't slipping. Any clutch will slip. If you hook your car up to a 20 ton trailer and you're making 1000hp, your clutch will slip. So there's no real reason to "try" to get your clutch to slip...

 

Yes. This is correct.

A great way to see if the clutch is slipping is putting it into a higher gear and get on it at a lower RPM. My girlfriends '90 Talon has slippage right at the beginning of the power/torque curve. It can be warmed up a little and it holds decent.

Drive the car like a DD without launching everywhere and a burnt clutch and spotty flywheel will last you another 10k miles.

 

I'm not disputing this, but wait, what? Could you possibly elaborate on this a little bit? This confused me (no atmospheric/altitude related effects on boost explanation like last week either!! hahaha)

 

pretty sure the ecu tells the diff to act a certain way when the e brake is up

 

Sorry.

 

Haha... I'm not actually well versed in how it works tbph. I just know that when the handbrake is applied, the vehicle disconnects the center diff. I think the chap who posted next is probably correct in saying that its an electronic disconnect. It says it in the owners manual on my IX MR.


No need to be sorry m8. Everyone has to learn at some point... I just don't want you to go all kiddywampus and try and burn out your clutch and in return completely destroy your car?

Asking questions is the best way to learn, and even silly questions to us are good questions to someone else!

 

Yup. The only stupid question is the one you dont ask and try to figure it out by yourself which usually ends up doing more damage.

 

Not to sure but are Evos the same as dams which have the adjustable rod on the clutch pedal assembly?
