Well since its your only rotary you been in,its hard to determin what you heard.
Some manual trannies are very quiet.

The whine,was it in the rear or tranny?Cause I have heard cut gears,and they whine like a bitch.High pitched.You probally heard a combination of engine and tranny,and I would say they were not cut.

I dont think even the SCCA guys cut them.
