Gasoline vs rich mixture LPG performance?

Some people say LPG coverted cars loss of some performance
i have weber carbureted ford pinto engine, single point LPG system

i can say there's almost no difference at all with advanced timing, high octane LPG and for about 1sec. 4th gear pulling loss its worth for my savings.

so, richen up mixture with LPG can reach gasoline performance?

Not with traditional propane carb system. You just don't have an acceleration circuit in the propane carb system. It is needed.
think about it. I've set up atleast 10 propane or dual fuel conversions, and yes they perform better rich with advanced timing, but so does the same engine on gasoline.
you lose performance and economy plain and simple
i've also done lpg and natural gas on stationary plants.
put it on a dyno. In america, the benefit of propane is longevity of the engine. Its hard to find a filling station. We just used a 1000 gal tank and pump on a farm. At that time the cost was about.35 a gallon in the 90's. Today, its a couple bucks, up to $4 a gallon.

New O2 sensors, TPS, MAF, IAC, new fuel injectors and fuel pressure regulator! Idle rpm is about 1500 when engine is warm and surges when truck is in drive and drops extremely low in reverse. Black smoke has covered exhaust tips and the rich smell is very strong from exhaust while truck is running. Truck has 180,000 miles and is a V6.
  • 1988 mustang gt running rich with idle issues? Hi, first of all just want to let you know its not a vaccuum leak. Freshly built 347. It idles eractic on cold start but then evens out and the cam lopes normally. Idle hangs for a minute if I hit the gas. Throttle cable is not hanging up either. After it reaches operating temperature the idle raises about 2 to 300 rpm? It also is running rich. I cleaned maf and the idle bypass. Thermostat is a 180 degree. I just don't know what else to look at.
  • Will high performance spark plugs have any benefit in a non performance car? To start I have a 2002 Ford Focus ZTS with 150000 miles on it. It needs new spark-plugs, and the only two types the store has that fit my car are Autolite Platinum and Bosch Platinum IR Fusion. My question is for my car, is there any advantage to spending the extra 14$ to get the higher end spark plugs or would it just be a waste of cash?
