stock impeller vs solas
is it better to use stock impeller due to the fact that by the time i installed solas impeller 11/19 my rpms where reduced?i run an rxp 155 with riva intake grate and pump wedge,rd air intake and inox j pipe.

Remember it's a 155 HP. So use the 155 mm props. Ie 11/19, 12/20
Sounds like you just need a little more power OR might
need to repitch just a hair to get optimal rpm's
If you ripitch and get the rpm's back up, you will gain speed
as well. Good luck and let us know how it goes.
I'm sure members in your situation would like to know
what it took to get to the best goal.
Few years ago, with just better air intake on my 185 gtx,
The 12/20 was the recommended prop, but I had to tweak
it to get to rpms. Once played with it a little ... whamo
Even tried the 11/19.. but that put me on limiter big time, go figure.
I suppose there is small differences from prop to prop as well
nothing is perfect

Also not all Solas Impellers are exactly the same so you need to either repitch or increaase power output. To bring the RPM up 100RPM below the revlimiter
