Just double checking re: the problem description, 

proportional to engine rpm, or ... to wheel speed?  I know you said engine

I'm thinking if it's wheel speed you may be able to eliminate a lot of
things in front of (i.e. engine related) the clutch.  

If on the other hand it's rpm related, & not wheel speed, the focus might
shift from the driveline, i.e. CV joints, drive shaft etc. to some thing
engine related?
