X s/c upgrade or more rpm??
Guys iv'e got a 08 rxpx done 42hrs, my question is which will give me more gains?
Do i go the mini rude upgrade and a rrfpr, or do i go a les cooke ecu reflash (8650) and retainers?
Also the ski is getting a 4" intake, 83mm nozzle and solas 15/22r prop at the same time.
I will do both boost and ecu but $$$ means only 1 at the moment!!

Id say go with the reflash+retainers first - the upgraded charger will function best with the higher rpm limit

I would say get the Riva drivetrain and get the 9.2K reflash and stay around 9k, your ski will really wake up at those revs.

get a c kit or something equivalent, sayers seems to be collecting a few down there in melbourne
run the rrfpr with the stock injectors.. keep the stock ecu, nozzle down to 83mm, 15/22 or 15/20 prop and bigger air intake..
save yourself the money in retainers and reflashing and get a new charger which would be cheaper... you after top speed?? then ignore what i said above... ski will still be quick though
i ran a c kit for 60hrs with my rxt and loved it... it was reliable and pretty quick for the ship that the ski is

stock #38 injectors with ckit? need 42s for xcharger or 48s for ckit level boost etc

as LONG as he keeps his stock ecu and aims for 8100 rpm setup and doesnt go for reflash etc.. may be a different issue then...
i clocked up 60hrs with the c kit with above setup.. wound the base back to 55psi in the end.. it ran great..
running the turbo with 50lb injectors... and rrfpr...
