I was talking to a guy who used to pull a hot 180 , i bought some parts from him, anyway he said that he used an electric actuator to engage the clutch packs on the PD , and had a seperate hyd oil setup to engage the packs with hyd pressure ; he said the clutches hold better running dry - anyone do this , they seem kinda fragile i would think running in oil would be better ??

I won't comment on what way is better for competition pulling but look at the design. Oil flow I think was primarily for cooling but oil obviously provides some lubrication, so where do you draw a line between the needed friction when pulling more power through the clutch than designed......
I have heard of several guys removing the power director clutch due to slipping. I have an oem coupling out of a tranny that never had a wet clutch.

Yea, I can fix that.....

My biggest concern would be the clutch disc breaking from heat , dont want to be in there every week replacing disc! !But maybe they were using a better material than stock

If they aren't slipping, they don't generate heat.
Rockford used to have two ratings for their clutches like the ones used in WD hand clutch and oliver pto clutches. One was dry and one wet. Dry was much more torque capable, but wet was much longer life when used to modulate speed.
