I let Shanton take the ski out and after 5 minutes he came back and said, "this thing has way to much power, it's ridiculous. I'll stick with my stock RXP."
It's a blast, I have no issue pulling away from Riva stage III skis. As far I know there is only one other ski in OH faster and it's a Turbo RXP out of Dayton.
There is more left in the ski and with a repitch it should have no issues breaking 81 MPH. Right now the ski is on the soft limiter with an 82mm ring, I have not run the ski with the 81mm ring as just purchased the 81mm ring and I wanted to get the prop repitched first. With the Riva pre-filter on the ski, it turns 8200 RPM and with it off is at 8280. It should be in the 8140-8160 range.
