yes, clutch isn't holding at the maximum torque and power areas...you definitely won't get true numbers

why would you dyno a car with a slipping clutch?

a slipping clutch is easy to diagnose...if you think that's the issue go test it

To test a slipping clutch the way I always do it is take a drive up a hill. Shift into a higher gear than needed, and floor the pedal. If your RPMs go up and your car doesn't accelerate, its time to go clutch shopping.

Exedy will not let you down. Twins are great.
