Good luck Hombre!!!! Looking sharp like a dart!

I take it you've decided to change it into a single purpose bike built for straight line track use? Is it set up for 1/8, 1/4 or top end?

My R3 is strictly for LAND SPEED RACING at Maxton, Loring, and Bonneville. It is not set up for drag racing, and is no longer street legal. IMHO bikes of this HP have no business on public roads.



Hellfire, you were interested in injectors. Here you can see how nicely my custom fuel rail fits with the much taller 1000cc injectors:


First R3 to use 1000cc injectors... and the only one that requires them.

Amazing achievement. I wonder whether you will garner the record before this machine detonates? Reminds me more and more of the 500 horse power VTX Green Monster that will also probably go up in a mushroom cloud one day soon Good luck...wear LOTS of armor!

I'm not to sure about running bikes at Bonneville on salt, it really bothers me to even watch it on TV. Salt is just so loose and rough, at those speeds it has to be just like riding on wet snow. There has got to be better places to run on two wheels. Best of luck.

My C38-91 finally arrived:



This setup will pump over .5 kg of air per second into the R3:

A close look at the impeller reveals secrets of the C38-91's efficiency and huge airflow capacity:




Compare the highly polished turbine blade design above to the drab impeller of the C30-94 below:

Wow! Night and day difference plus an extra vane to boot.
Send me the old junk and I'll recycle it for you.
I'm really hoping to get to Maxton to see and hear this beast.
Less than a month away, will you be ready?

Don't think she'll be ready by April 2nd Cal, still have wiring & tuning.


Need a longer blower bend, but you get the idea above. I'm also going to move the blower 10mm outboard.
