Have anyone experienced clutch slip that's not audible.... Would it cause a dramatic power loss on the dyno.

 

Yes and Yes

 

Lol..... thanks bro

 

If you can't hear it or smell it then look at the dyno graph. Lay RPM over roller speed and the lines should be straight and linear to eachother. If you see the rpm is a straight line and the roller speed starts to curve and fall off then either the clutch is slipping or the tires are spinning on the dyno.

 

Just left the dyno.....replaced the clutch and flywheel.....picked up 25hp!!! A fairly large gain on an AM car.
Engine was making around 200 with the " prototype " clutch. Was weird though. Absoutly could not hear the slip on the dyno. At the track was a different story. Just a mild b series AM car. Keep this in mind if you find your self scratching your head.

 

Also....anyone sell everything to log clutch slip....would like to have this info for my car.

 

you couldnt tell mine was slipping on the dyno unless you looked at the roller speed on the dyno vs rpm. I went to the track and it sounded like i had a powerglide, lol.
My HP didnt go up a whole lot when i changed the clutch out, the torque went up quite a bit. It had 390tq on a Dynojet with the clutch slipping, then it made 470tq on a Mustang without it slipping, on less boost.... If I remember correct
