If you read the book The Construction Of A Gasolene Motor Vehicle 1901 has a whole chaptor on vapor carburators, and points out that the residue that is left over is a problem, and advises agenst it for use in gas engines.
Looks like there are dodge stratus lights on there, and Chevy HHR tail lights?
When I just put in my engine in my caprice, I pulled the fuse to the fuel pump, and it was still idling, but died after a few seconds . Then I unplugged the fuelpump its self just to be sure, and it still ran. When it died it could be restarted and it could run a little. The only fuel it was getting was from the emmissions vapor canister
85 Chevrolet. 30 MPG or bust!
I'm sorry but when the most exotic road-going machinery in the world (Ferrari Enzo, Porsche Carrera GT, Ford GT, Corvette ZO6, etc.) struggle to achieve 1.0 G on the skidpad and the Fuel Vapor boys claim 1.7 G with a trike it makes me suspicious of all their claims.
That said, I still like the concept if not the execution.
