Prop suggestions now with Rude SC?
Ok, so in addition to the mods below I am adding a Rude charger and RRFPR. I know I am going to light the prop up that I have now. SO I am looking for any suggestions what a good starting point may be? I was thinking 14/22?
76.7MPH @ 8180 RPM, 59 deg salt water, 65 deg air, sea level, 6 bars of fuel, 4” air intake, Riva stage 3 SC, XS Intercooler (w/bleed mod), Solas 14/20.75 (4 blade), Green Hulk waterbox, 80mm nozzle, Riva intake grate, NOPAS, Jim's rideplate mod, RXT-X pumpshoe-rideplate-grate, 2 degree wedge, added VTS, Riva sponsons, 42lb injectors, stock ECU, 160 degree thermostat mod, free mods.
How many RPM's did you gain from a Stage 3 charger to a Rude?

Hmm, so go to 15 on the lower number from 14 and 20 from 20.75 on the top number?
What will I gain by going to a 15 on the bottom number verses the 14? Where do you think the top number 20 may end up?

I can pull a 15/23.5 (8,080 rpm) in my T-X with stock X sc right now in best air.
In bad air I am running 7,900 rpm.
This is all in cool conditions, so I want be able to pull that prop in summer.
I am going to try to run a 14/22 in my ski this summer. Its a R and D pro pitch.
I think a 14/22 will be close for your setup. I saw about 200 to 250 rpm gain going from S3 to Rude1, and a butt load of acceleration gain.
I thought i saw were you were going ecu?????
