For the guys that want a cheap 77+ MPH RXP
Here are a few pics of my Cheap Set up (Hopefully 77+)
I have had a few RXP's and always want them to be fast, but
Since the cash isn't always there. ( Not a high Roller) I need to look for cheap, but safe ways to make my ski's fast.
Well here is another one of my set ups.
1.)Rear home made 4in intake.
$40 for adapter and $8 bucks for hose.
Use your stock Rear air inlet and reshape it.
2.) XSic with Home made bracket similar to a Riva about $200 bucks
Yes, i understand not everyone can make a bracket, but it is easy.
3.) Adjust rear exhaust outlet so the Rear intake and IC will
fit without takeing any of the opas out and I use the stock exhaust exit location. $20 Bucks for a 90 degree pipe, some T-bolt clamps, and cut up your stock exhaust hose.
4.) STG III SCer $850
5.) 42lb injecters. $200 Rotax
6.) 14-19 Solas Off my shelf! ( hope it works) $150
7.) Rapids Exit nozzles 81MM $75 Just to machine it
8.) Dynotune Boost gauge from Muddy River. $85
See I have less than $1500 in it and I am hopeing it Runs 77+
What do ya'll think?

Just found a 15-19 R on my shelf behind a bunch of crap, so I will
be taking it in a spare pump to test everything today. I will post tomorrow. I sure hope it pulls hard. Gonna have to fill some big shoes, since my B-kit ski is at the lake house also.

are you running any grates, ride plate holes filled, wedges, skegs?
combinations could have you flirting with 80

you wont be hitting 77 with a stage one prop, you'll need the 15/19, the only difference between yours and my setup back when i hit 77 i had the OEM intercooler and the rest what the same
sorry i had the 4" front air. this year i made my own rear YAY.

Becareful testing with that neck injury you previously had

Good recipe, but the 14/19 won't take you to 77 mph ... the 15/19 might, but if it does not, a 15/20 should get you to 77 mph (with possibly some cleanup under the ski). Good setup, great bang for the buck.
