WFO expanding!!! 80+ RXP!!!
For those not familiar with Rich and WFO Performance, he is IMO the best on modifying GPRs with incredible attention to detail and craftsmanship. Since going into this full time he has decided to take on the SeaDoo arena.
After working on John's RXP (2fun4u) there is another member to the 80+ club. Rich was able to do this with a Rude SC and stock ECU. First time out it ran 79.8 with John sitting on the seat!!! Several times the same day it ran 80+ even heat soaked. This didn't happen over a long period of time and many trips back and forth to the water, just took his normal time paying close attention to detail and one trip to the water with a very happy customer.
I'll be out in Texas Sunday and plan on riding this for myself. Can't wait!!

Nice work Rich. 80+ with a stock ECU isn't easy. Kudos brother.

Since I am working on boats full time now, I decided to take on this 07 RXP. Lots of help from Jerry and the wonderful 4-Tech Performance store.
The boat previously had a Riva IC, Green wheel, 42lb injectors, 3" Riva air intake, 15/20R prop... average speed was high 74s and best speed was 76+. I upgraded the SC to a Rude, and installed the RRFPR, and custom 4" intake, and pitched up the prop.
Best speed was 80.4, with a few 80.3s, and it settled in when fully hot to consistant 79.8s. Rpms 8120 with the 81mm ring. Boost 12.4 lbs and using the Riva BOV. Stock rideplate with Jerry's skegs, and no wedge.
