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

 

+1 why would you even do all those mods and disregard the clutch.

 

i know it wasnt the smartest thing but hey i couldnt wait for the new feel so just had to. yea next thing is a clutch. a must. excedy twin here i come!! lol

 

whats the method?

 

no fuel pump???

 

aww yes. walbro 255

 

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.
