Super Miata twin disc clutch + flywheel
 

SOLD

Less than a mile and already loading it to break a trans on a dyno? No break in period?

Did you ever get a plot of the run which bombed the trans? What was the torque?

Plenty of breaking in between 2 dyno sessions and trips around the block/trailer loading and unloading.

Made 343 ft-lbs, but the trans is perfect. I knew it wouldn't last long on the track so while the 6 speed is good, I did the swap so I can sell it and my diff.

Seriously though, this thing has all the revs

Maybe I don't know enough about clutch break in procedures, but I was under the impression that the instructions say 750 miles and a readjustment before heavy loading. That the highest rate of wear is in the first 1500 miles. I guess I should schedule my dyno session in with the 20 miles I have on the clutch.

I thought your first post eluded that the trans was destroyed because of the power.

just post pictures of it and they can judge for themselves.

I've been driving on one of these with the Kevlar disks and they hold up great. Friction feel is almost stock. Only issue I have is stop and go traffic or rushing to start from a stop I stall occasionally.

Here are some pics

I am interested! those are some interesting marks on the flywheel for only a mile of use? if you could estimate- how much heavier did the clutch pedal feel vs stock?

also im interested in what happened to your 6 speed... as I currently make 340whp and 300tq and was hoping to get a little more power out of my trans/diff. (400whp 350tq was the goal) I also track the piss out of it and know that I'm going to be maxing the mechanical limits of my drivetrain :( also even more scared after seeing what happend to Greg Peters. Seems as though un-sprung clutch disks is will ultimately killed his trans(s)

The marks may be a little bit of input shaft lube that flung up on the disc. Its all smooth as butter and feels perfect still.

The 6 speed trans is available and in perfect working condition, just haven't listed it yet. Has the 5xracing upgraded shift bushing and turret rebuild kit for perfect operation. Not sure how excited about shipping the trans I am though.

And you are located where?
