    Propane Mixer Requirements

    I am currently building a turbocharged Ford 2.3 engine for racing. I'm hoping to manage 350-400hp and plan on using my readily available Impco parts. My dilemma is that I seem to be on the borderline of using one 425 mixer. Should I just fabricate my intake to accept two mixers? Or is it...

    propane requirements for a turbo big block

    I have studied the Impco catalogs for info on 425 mixers and found that they will flow around 460cfm and are good to about 300hp. My question is, on a turbocharged big block V8 capable of 700+hp would you require more than 2 of these mixers to adequately fuel this engine? I'm thinking along the...

Being a gas I know there won't be any puddling, but these manifolds are designed for air travel while the fuel is injected right into the cylinder. I believe propane likes longer runners, so I am...

    propane for high performance

    I'm about to convert my car over to propane using standard Impco parts. I have a 360 Mopar engine that will be running 11.5 to 1 compression. The heads have stainless valves, bronze guides and hardened seats. Everything internally is pretty much new, as is the machining. I have chosen a Weiand...
