I'm running a stage 2 as you can see from my listed mods. I'm turning an out of the box 13/19 @7190 WOT, how much will the rpm's drop with the Riva/Solas setback 13/20?

SOMEONE must know the answer to this question? I know that OTB impellers vary but what is an approximate rpm difference?

Voodoo, I have a stage 2 as well, turbo tube and the advent cdi, otherwise our "set ups" are about the same. With a box stock 13/19 - 7280, with the set back 7250. Per my gps, and racing my friend's Gpr, I picked up about 1.5 mph. The set back works good with a strong stage 2. I have a new 14/20 from Impros still in the box, when I get time, I am going to try it, my tuner does think it could be too steep, but worth a try.

Wow, I'm surprised there isn't much of a loss of rpm's at all! I like the sounds of this prop, better recovery, better hole shot and more top end!

Why didn't you ask Carl ?

Because then I wouldn't get to hang aound on the forum and ask stupid questions
I should just have Carl set my 13/19 back and pitch it up but I left the d#** ski up north
