what impeller and intake?

[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.

smells like a freestyle engine to me, why race it? it wont hang with sxrs or octanes or anything for a second anymore...

Thats not true........... watched Johnny Smith give Farthing a hard run back in 04 while Johnny was still on his SJ............. Farthing was on the Black SXR..........

It is all in the rider..........

sounds like you need a steeper prop.............

About 2 months ago I would have said B.K. is full of it-I bought a prop from him that should have killed my sxr every where but the bottom end-HOLY poop batman-he said it would be killer through mid all the way to top and would not lose any top And I then thought to myself-well-he's tryin to sell me a prop-WRONG-He was sooooooooooooo right!!!!!!!!!!!!!!!! I used to think he was messin w/me-NOT-now I consider B.K. the gospel w/this stuff!
