Les Cooke A-Kit X Impeller wheel?
Anyone using this on a rxp-x? I currently have a les cooke 4 inch intake, r&d intake grate and r&d free flow exhaust atm getting 72.6mph @ 8160 rpm. Planning on getting the wheel and have a solas 15/22r, jus wanted an idea on rpm's! Whether im going to have to go with valve retainer's and les cooke re-programmed ecu?

As long as you are using the stock intercooler then stock injectors are fine. No need for an after market ECU. If you have an after market external intercooler then you will want to run 42 lb injectors... still no need to run a reprogramed ECU to run that supercharger impeller.

Im aware of the reasons to go with a lightweight valve train and ecu etc, what i was trying to get across is with my current set-up and adding a 12lb wheel and a solas 15/22R prop do you think this will push me up to my rev limit hence the reason to go with a les cooke 8400 ecu and retainers? Or should i go with his 8650 ecu and also do the valve springs and valves? Just would like an idea on rpm increase with the wheel and prop?

If you'r on the limiter bend your prop a little,can be find in the how-to section,very easy.
Since you'r from australia if you want a reflash go to seadoo centre they are in australia to,easy as that.
Good luck with your new mods.

stock ecu and 15/22 will work but you will hit the limiter. no need for lightweight retainers and all that stuff if only going the 8400rpm reflash but if you go 8650rpm or more than do the lot. I have been playing with my props now for a while the three blade is away getting tidied up but will be set at 14/19 and i am still mucking around withthe four blade which is currently set at 15/21 but I am now using a 84mm nozzle so my revs have changed slightly.
I used the stock prop for ages with the A kit, 4" intake and worx intake grate with no dramas at all when using the stock ecu and rpm was around 8140 if i remember correctly when using a 83mm nozzle. With the stock nozzle I was smashing the limiter with that setup

If i go with the mini rude, les 8650 ecu and retainers will i have to go with injectors as well?
