Ive been doing some thinking about the price of gas and was wondering if propane is cheap enough to warrant the change over? Has anybody here ran it before, or currently? Is there a power loss?

I know a few toy guys that run propane! Because carb like to stall on angles and with propane the motor will run upside down and the power should be close ~gunsmilie

not true on the power propane is still not street legal how ever the power loss on a toyota is about 40% u take our little 100 hp motors and subtract 40% = not worth it to me

never heard of propane not being legal to run on the street. What about those old school vans with propane conversion.

The "street legal" issue in California is the smog check and passing visual inspection. On a post-1975 vehicle the vehicle would have to be taken to a referee and go through that process. There was a requirement in the past that LPG (propane)/CNG (Compressed Natural Gas like the buses run) conversions had to be done by a LPG/CNG certified installer and get a sticker to allow the vehicle to be filled, I haven't seen mention of that lately. LPG has a higher octane count than gasoline but lower BTU's so it runs cooler, but, because of that you could work the heads and bring the compression up in to the 10:1 or higher range with no problems and possibly bring the HP up with it. Conversions on later model engines usually require the distributor to be changed to a non-computer controlled one as the ECU gets the timing fouled up. Roush Racing just released a "street legal" LPG conversion for Ford F-150/250, only $9k, 8-hour install time and no loss of power or torque, the Mustang crowds are already salivating over it and thinking about how to pop it in their ponies. Remember too that UPS ran propane trucks in California for several years. Also, look at www.impco.ws, a California company that makes a LPG conversion system that works with a Holley carb, street legal too |
