Clutch Break In Before Dyno.........Why???????????????????????? ?
The last time I bought a new clutch I did a 400 mile break in period before I ran it on the dyno. I am thinking about replacing it with a new one. Why is it necessary to break it in before a dyno...I can understand breaking it in before going out on the track...but why the dyno. You just put it in 4th and it is locked up when it is moving..what does it hurt.
Thanks :rolleyes:

It's fully engaged on the dyno, but it can still slip under power. The break-in period on the street beds the clutch disc material. This provides maximum holding power as well as heat cycles the material several times. This actually makes the material stronger and able to hold more by increasing the friction and evenly distributing things. Also less likely you will get hot spots on the flywheel afterwards. :cheers:

I agree with the break in for regular driving or track use. Helps to stop chattering etc. You definately don't want to slip it or abuse it for a while. On the dyno the clutch is locked up. If it slips on the dyno then something is very wrong with the clutch or very right with the engine.(overpowering the clutch) I would like to hear other opinions , though. This is just mine.
