05 rxp with mods. Need help/ opinions
Just starting to mod my ski, scared to blow it up. But I've been looking around and I decided on buying a les Cooke wheel from " spanners" on here. I bought 42s and also wondering on what prop I should get? 14/19 or 15/20 prop. I'm in fla and ride year around. I really don't want to have to re pitch or bend it. I will be going to do a fizzle intercooler eventually. Will I need a fpr as well?

I'll keep this simple
all you need is a 11lb wheel like the et 127 and a 14/19 since your In the heat otherwise a 15/20 is what you'd require and an ex IC
lucky 13 cone to tune rpm
very sinple safe easy setup. 75+ pending how much time you take to set it up
no fpr needed for that wheel. Just 42s

I paid for the les Cooke wheel, so that's what's coming. Hopefully it'll work out good. I'll order 14/19, does it need to be an "r" or "srx"? Idk what those prefixes mean

R props are Riva props
some pitches are only available in R
the srx is the correct 159mm prop for older skis

Go 14/19. Your in Florida. The heat that blade will be best
an ex IC and colder air a 15/20 is needed

One prop is not going to do everything buy one now for current mods, 14/19 as suggested, or buy a steeper one for future mods and be down on rpm until you do the mods.
I had an 04 RXP with 4" intake, ET127 wheel, 42lb injectors and a 14/19 repitched by Impros to 15/21 kept me off the limiter. I'm in Canada with cooler temps which helps turn the steeper prop.
