Stage I ++ 06 RXP speed 77.8 mph
Riva Stage I + intercooler + RR ECU
I want to thank Jason (Sandrock) for helping me get this speed.I told him that I wanted to get near 75 mph and keep it reliable,he said (no problem )and set up a kit for me .Today the ski ran 77.5 ,77.7 ,77.8mph .I still have to repitch the prop ,the RPM's are 8520-8560.

SWEET! Mike have ya filled the plate holes yet? Removed the nose cone? Added skegs from Jerry? There's sum more speed in that puppy! How would you compare it to your Yami?

The ride plate is filled ,nose cone is still in the box, no skeggs yet ,getting ready to order the them.
The RXP has a better holeshot and maybe a better midrange pull than my GPR 1300 for now. The topend is near the same, I have been 78.0 on my GPR ,but it is not as consistant as the RXP. If they were to take off from a dead stop it would be hard for the GPR to catch the RXP.I have a new 1500cc motor Lowell just finished for the GPR,I have got to get my GPR faster.The GPR is mine and the RXP is my wifes,I don't know if I could sleep if my wife outran me .

Awesome speeds! Definately get some pitch in that prop before you float a valve.

The I/C is the XSPOWER
Have not checked the exact pitch on prop
It also has the Riva OPAS blockoffs that I ordered from Jerry's store .www.4tecperformance.com Thanks Jerry for the very fast shipping

If you have a stock block I think those RPM's are a little high.

The rpm is to much but that boat is fast for what you have. Some guys dont think i can get those speeds with just a ECU IC PROP GRATE AIRFILTER AND WEDGE. if they dont think it will do 77 they can come and find out. but your wife is going to beat you a$$ when you run her with the gpr
