Exedy Twin HD Slippage

Hi guys,

I own an Evo 7 with all Ralliart bolt-ons and stock turbo@22psi

I had an Exedy Twin Carbon before and it showed slippage in 4th and 5th gears... I was told that Carbon clutches only grab when super hot, this condition is impossible to reach during daily driving, if you do not "burn" the clutch.
So, I bought an Exedy twin HD ceramic, thinking that the problems with slippage would disapper, BUT for my surprise at 1000miles of use it slips in second gear@full throttle.
Very disappointing.

Now I need to know what is going on because my car is at maximum 310whp and any clutch is up to the task OR IS something that I do not know that is causing this sllipage...

Please, What do I have to check?

Thanks

Did your twin come with a new flywheel? If not did you resurface the flywheel? Did you adjust your clutch pedal? It definitely should not be slipping...

A. Bought it new
B. Maybe, 400miles of break-in only
C. do not need to answer


Weird thing is that I went to Mitsubishi for a check, and the pedal adjustment is right and during the test-drive together with the mechanics the car did not show any signs of slippage.

*My car is in the garage for a long time (1,5 months) for personal reasons, Does this situation contribute in some way for a slippage?

I read some manual and it said 750 for break in. Then I did a search on here and some people broke them in and some didn't. Letting the car sit will not cause slippage. Maybe you were spinning the tires when you thought it was slipping... Continue the break in to 750. Then start to drive a little more agressive. The ultimate test for slippage is putting it in 5th gear around 3500 and wot. Don't do that if you have a big turbo upgrade though or for too long because it puts a lot of strain on the engine.

every twin should be 1000 mile break in
why?
better safe than sorry
If is slipping, and as you claim its brand new, then obviously its something with the clutch.
get a flash light and goggles, check under the hole in the tranny to see if the Throw out bearing is good and everythng is working fine (have someone in car press clutch)

if you dont get anywhere, then
tear her apart again
