massive crowd at the 2009 Seven Stock event in Irvine California. Turn up
Handbuilt 4-Rotor Engine
This was a project that took about five years of weekends to put together.
There was a lot of trial and error as jury-rigged parts were improvised and
revised, leaks were identified and plugged, and byzantine electrical
diagrams were decoded. It still does not run smoothly, as there likely is
a problem with the intake system that has prevented smooth timing at idle.
But she runs!
lots of people wanted to know where the E-shaft came from: it was custom
ordered from a shop in New Zealand.
BMI Racing. Four Rotor RX8. Snap-On Tools. And a lot of noise...
Mark Lenardon Presents
BMI Racing has successfully built the an amazing sounding, rare to the eye
and ear, 4 rotor RX8. From any point on track you can hear the pilot, Brian
Wilkerson, stand on the throttle in which it causes your eyes to shake and
grabs your attention like a train wreck.
As being a new and great sponsor for BMI, Snap-On is proudly displayed on
the car showing only the best is used on this beast.
Hell on wheels barely describes what my first impression was of this thing.
