Well when you say novel I guess you really mean it--this being an atypical valve arrangement? What else can you tell us about this?
In development at dyno stage.
I am retired from the project
Air cooled, showing one advantage of methanol.
Top fuel drag bike application.
Single rotary valve for gas exchange.
For cylinder fill it is like opening the garage door, so in the early stages it only needed 22 psi.(supercharger superceded with turbo)
2.3 litre swept. 10.5 static.
500bhp @ 5000 rpm on the dyno for a 10000rpm engine
Methanol with nitro up the sleeve, twin fuel injectors with a normal return to tank system.
The drawback with a rotary valve is it compromises the chamber shape.
The key to rotary valves is the seal design, this one worked and worked well.
Twin flame ignition which needed only 26 degrees advance, greatly reducing what we call pumping losses.
BSFC numbers are sad which relates to the proposed F1 fuel specs
