I have given up trying to interpret the results from flow bench tests,as I believe its only a small part of the overall scavenging regime.
Same with using CNC Jaros type scavenging machine results - this gives the opposite effect, in that is it shows the velocity and vector directions
but takes no account of bulk flow.
The best setup is that used by DEA, a pulsed flow visualizer, but im not that rich.
Here is the best example I can give re the flow bench result.
A reed cage with a nice smooth aerofoil type splitter in front of the reed tips flows way more air than the modified cage I have developed with a thin splitter
and a flat wall,perpendicular to the flow directly under the reed tips.
Guess which setup makes way more power.
VHM show big gains in flow with a flat top piston and a timing edge radius, but the dyno result though near on 1 Hp in near on 50 is nowhere near as significant a result as you would expect.
Ive got a thing thats unique and new.To prove it I'll have the last laugh on you.Cause instead of one head I got two.And you know two heads are better than one.
