Tweeking the 15/19
For those of you that have a 15/19R and have had to tweek it, did you have to add or take away some pitch to achive your desired RPM's and also what RPM's are you guys running these props at?

That all depends on which supercharger you're running.
Rude Chargers i add pitch.
Anything less i decrease pitch.
These impellers really like a solid 8500 with an occasional flash of 8550

Jerry I ran it out of the box with the 81mm ring and could only get 8400 and 80 mph so I decreased the pitch (2mm) and had to run the 82mm ring to keep it off the limiter but could only get 78 mph. I was thinking of adding a little pitch (1mm)from the way it came and giving it another shot. I like the hole shot with this prop but so far I had better top speed with the 15/20. Any recomendations???

About time you got that prop! How is the whole shot? I never did ask you that! What part is next?

I wouldn't spend too much time dialing that prop in right now. You will loose 200 rpm when it gets hot out. Last year I ran the Skat 15/19 in the Spring/Fall and had to run a 15/18.5 in the Summer when it got hot. Both with the 82 mm ring. You can't beat the hole shot and acelleration of the 3 blades. I found a boost leak that I didn't know I had, which I have repaired and I added the Riva rear air intake and wedge. Also put in the Riva 15/19, which is not exactly a 15/19. Ski is ready to test, hopefully in the next few days.
