    Solas 15/22

    I know most people are using the Skat impellers, but has anybody used the new Solas 15/22?

    A friend of mine tried it on a stock SHO and it had 700 rpm loss.

    It's a great top speed impeller & performs real well in the midrange but cavitates much more off the line than the Skat swirl. I never did a true back to back test, but it was consistently 2 mph faster than a Skat pitched to turn the same rpm(~7700 with 83mm nozzle). I haven't used it since going to a reflashed ECU because when I tested it I wasn't able to turn more than 7940rpm, even with a 85mm nozzle. It has WAY more root angle than the 13/22R Solas that Riva sells, so if you have a stock or stage 1 ski this is not for you. My testing was done using a C1 wheel & upgraded intercooler, so IMO you will need at least a C3/B1 & a good intercooler setup to achieve 8300+ with this impeller. I had mine trued to 15/22 & blueprinted before it shipped to me, so I don't know what the out-of-the-box pitch was but another poster measured it as 17/23...posted in this thread:

    Here's a comparison pic with my 15/22(right) sitting next to Riva's 13/22R Solas DF(left) so you can see the difference in root angle. For the GPR guys who know what I'm talking about, the root on this DF is comparable to the VX prop.
