Have any of you guys seen a still for making moonshine? There are great ways to cool alcohol or in this case heat the fuel using these techniques. The way to put more fuel in contact with heat is to take some copper 3/8 pipe and wrap it tighly around the coolant lines. I would guess there must be some gain to heating fuel in that it only need to be heated a little more then to ignite. If you get the fuel close to its combustion temperature would you have to be concerned about preignition of the fuel?
One of the guys at work used to work for a local Toyota dealership and was talking about how they used to have to replace fuel pressure regulators on Camry's. He said that after the regulator had been replaced that the customers would complain about the fuel economy their Camry's were getting. He said that the Camrys had a little hesitation but excellent fuel mileage just before the regulator went. Has anyone tried to play with their fuel pressure settings?
On the propane topic, I know a guy who drag races an Oldsmobile with a 455 Rocket that is turbo charged on propane, he has said that he can run insane compression ratios with propane and a turbo on these engines. Have any of you considered increasing compression ratios also, this works very good with pure ethanol or E85 even. Ethanol has less BTU than gsaoline but a higher octane which would alow you to run higher compression ratios which, make an engine run more efficiently.
I know I am new to the forums, I really enjoy them too. I am hoping to use the info from you guys to help me get amazing FE from my newly purchased '97 Metro.
