Riva sc wheel & power pipe combo
I'm looking for some input on the gains I saw today with these mods added to my stg 1. The sound, I love! The extra torque, I love!
Previously with the stg1 & stock prop & saw 71.4 @ 8200 rpm on 3/4 tank. The prop grabbed at 7500 rpm out of the hole & was strong all the way up! I had impros add some pitch to the stock prop & he gave it .040. I ran this prop 'cause I haven't picked up my swirl from him yet.
Today on a very full tank it got 71.5 mph @ 8180 rpm & it would grab at 7760-7800 rpm on a new wear ring even. I'm assuming I gained some rpms on top with these new additions since the prop is taller now & i'm still near the same rpm as before. It's the pull out of the hole I'm wondering about. It added 300 rpm compared to before. For you RXP pro's, would a 14/19 spin like the repitched stock prop in this case? would a 15/20 do me right, now?
I am very anxious to run that 13/18 swirl this weekend!!

I would shoot for a 15/20. It will be 1 mph faster than a 14/19 at the same RPM

You guys don't know what yer talking about....
Thanx for the info!
You think the 13/18 swirl might be good at 14/18.5-19?

I would definately give the swirl a shot to see what it does. The 15/20's and 15/19 3 blades have been proven best with the RXP's though.

The solas 15/20 is going to be faster than the swirl will be at any pitch with your level of modification.
If your after acceleration and holeshot= swirl
if you want every mph out of your modification level= solas
