Please give us a quick rundown of your design and thinking. There are many folks on here who would be willing to help out.

There are also many who are quite critical. But, if you design and build with good science in mind, they usually go away and leave you alone.

I'll start the questions off with:

Are you attempting to completely vaporize the gasoline?

Are you attempting to thermally "crack" the fuel chains?

Thanks for your contribution to this thread.

Both. Small fragment burn at start up. Then use exhaust heat for vaporization.(need too weld the cat in a enclosure still). Control systems work like a waste oil burner or high eff furnace. The converters always been at the wrong end of the engine LOL. Its not an attempt that's what convertors do

The first sheet speaks of fuel usage in gallons per min. but on the dyno sheets (best I can tell) flow is gal. per 30 sec., so to convert to lb./hr, multiply by the fuel mass per gallon (~6) and then by 3600/30. Then to get the standard B.S.F.C., divide this result by the power at each RPM. e.g. at 3500 RPM the 'Werner' system uses 0.058 gal/30 sec to make 115 HP, so [0.058 x 6 x (3600/30)]/115 = 42.76/115 = 0.363 lb./HP/hr.

At the same RPM, the Rochester carb uses 0.088 gal/30 sec, but makes 135 HP, so the B.S.F.C. is 0.469., thus the Werner used only 0.363/0.469 or 77.3 % as much fuel.
Thanks Bill. Not to bad for no other mods.maxc
