Whirlwind Propellers and what now?

I did read a post a while back that said the plane had lost a couple knots going to the 74RV vs a 200RV. I hope that was for some other reason since I was under the impression the 74RV is faster.

The 74RV was specifically designed for the higher HP motors, so if you're running at 180HP motor and go to the 74RV I suspect the loss of speed is to be expected.

How about if you went from a 200RV to a 74RV with a 205hp motor?
