So I have an upgraded clutch/flywheel/LSD setup I need to get installed. I'm also looking to add a K-Pro setup so I can (finally) tune my car properly.

I found a shop (off the Hondata website) that can handle both the tranny work and the K-Pro installation+tune. The problem is that because they're a little backed up, they want to break in the clutch on the dyno during the tuning process rather than on the street.

My clutch kit (Clutchmasters FX300) has a carbon kevlar full-faced disc that I've read are susceptible to glazing if not properly broken in. However, the mechanic/tuner assured me that it would be OK to break the clutch in on the dyno so long as it's allowed to heat up and cool down consistently.

What do you guys think? Is he BSing me or is it possible to break in a clutch on a dyno? I don't want my clutch to crap out on me after 10k miles...

Anyone with an opinion ?

Are they planning to run the car on the dyno for 500 miles minimum?

DAYTA

I don't know about 500 miles, but they are planning to do a full dyno tune including partial throttle which should take 10-12 hrs total.

I wouldn't be worried if I was running a puck clutch, but since it's a carbon kevlar disc I'm concerned about glazing issues.

List the manufacturer's clutch break-in procedure and we'll be able to give you a better idea.

DAYTA

There isn't a break-in procedure specific to Clutchmasters kits that I can find.

The industry standard process has always been 500-1,000 miles of normal driving (preferrably stop-n-go), no slipping, and no hard launches .

The manufacturer suggests a minimum of 500 miles for break-in under partial throttle, avoiding heavy load and high RPM shifts. If they overheat the clutch and glaze it you're SOL.

Game over for the dyno break-in, assuming the above information is true.

+1. Break in the new clutch. Drive around for about a week, and you'll be ready to go with no worries of ruining it on the dyno.
