Help with Correct Prop Pitch and Fuel Injectors for My 2004 RXP

[jjspyder]

Need some advice for the correct prop pitch and fuel injectors for my 2004 RXP. Below is a list of my current mods:

Rotax Racing Supercharger Wheel
Fizzle Intercooler (1st gen)
Supertech Valves
Riva Power Filter Kit
Riva Pro Waterbox and Thru Hull Exhaust
Solas 14/19 Prop
Top Loader Intake Grate
OPAS Blocked Off
CanDoo GPS Speedo

I currently have the stock fuel injectors. I am wondering if the 15/20 prop would be the best since it is basically a stage 2 ski and that's what Riva recommends for a stage 2. I appreciate any help. Thanks.

Petty sure you need 42lbs injectors

[jjspyder]

Anyone have some 42# fuel injectors they are looking to sell?

Would Bosch 48# injectors be too rich?

Way too rich!

You will need these injectors

and the 15/20R is the best choice in impeller

always install a fresh wear ring with a new impeller

how much boost does that wheel put out?
An X charger would be a better setup than that wheel, I'm guessing

[jjspyder]

I'm not sure how much boost I'm getting. I haven't installed a boost gauge yet. I'll probably wait til the supercharger needs rebuilt and consider getting an X charger. I put the Rotax Racing wheel in last time I rebuilt the supercharger and it felt like a significant increase over the stock wheel even with no other mods at the time.
