hitting rev limiter

[coolshirt]

just added the xcharger to my 2007 rxp. bangs the limiter from the dig and hits 8200 up top.ski was perfect b4 the install turning 8000.
current complete set up now is, stage 1 with rear air and now xcharger and 42s. i have the 14/19r in there now.
would the 15/20 be to steep?

Don't touch a thing. Add the lucky 13 pump cone and you'll drop rpm and maintain same speed

i have the wedge.. looks like its same price as a new prop.. so would the 15/20 be to steep?

Take green bullets advice ! The lucky 13 will take the prop spin away and lower you're rpm along with being able to adjust it for future mods and weather changes .

I've done a lot of testing on my personal ski with the cone and even fuel economy at crusing speeds has improved with the more spacers used as well. I'll admit I was a doubter on this cone until asked to try it and now I'm amazed at what it can offer as long as you take the time and adjust to your ski. Heavily modded or stock the cone will give gains

ok to answer my own original question..
the 15/20r is the ultimate pitched impeller for my ski.i put one in 3 days ago and took it out today.

i went from a full level 1 with rear air and a 14/19r prop{banging the limiter} to a xcharger and 42 injectors to a 15/20r prop.
rpms were 8050 today and the ski did 74.5 mph gps in 90 degree heat.
