What impeller and intake can I best use for racing?

[Peer]

Hi,

I have a 2002 superjet with the follow specifications:

760 ported cylinder, by JR Magoo's ( wide open exhaust ports)
Pro design girdled cool head with 34 cc blowsion domes.
44 mm mikuni carbs with spacer and carbon reeds and fly flame arrestors.
Factory B-pipe.
MSD enhancer.

The engine runs 7100rpm/ 53.6m/h with a Solas Concorde 14/18

What impeller and intake can I best use for racing?



Thanks Peter.

r&d double deep intake grate works very well
as does there ride plate
Also a shredmaster works awesome

Thanks waxhead & yamah0,

Can you also give me pitch for a good working 144 mm impeller? ( for a max. top end speed )

ne you have is fine
its a taller one than i would run with that combo
goign down is only going to lose you top speed
