xp800 upgrade to magnum pump Q
need info for upgrading my xp800 standard and using magnum pump. which magnum pump to use and what is the best impeller for it.
my ski is stock, except the airfilter.
and also what single pipe is best for it? would this 2 combo(pump n pipe) is a good setup for close course? just for fun ski not race.
also, where to buy the pipe and pump?
thx for helping,

this is a good setup for a rec boat...
spec 2 pipe
miller head w/ pump gas domes (42cc?)
re-flash mpem (I would use msd enhancer)
large hub rfi plastic pump
16/24 swirl impeller
r&d 85/88 nozzles
top loader intake grate (umi or r&d)
complete umi steering
you can re-jet the stock carbs, but 46mm aftermarket carbs will give you more power & less fuel range. a lot of racers (including me) have had good results with novi carbs.
expect 62-63mph with the above setup and arm pulling acceleration.
no need for magnum pump.

Yep I really liked the RFI pump in my SS HX it makes a big diff in the rough stuff & is realitivly cheap,around $450/500 with a prop.
I can sell you pump if you want.
PM if interested.

try seadoo.net for the spec 2 pipe. you can prob find a msd enhancer over there too.
