[QUOTE="altfuel1991, post: 188827, member: 1211"] The Impco mixer is designed to flow the correct amount of fuel and air to supply the BTU's needed for 325 horsepower. The fuel flow can be increased(richened) but that will not help since the air flow cannot be increased to match. The mixer is calibrated to maintain the correct air/fuel ratio throughout the rpm range. The OHG X450 mixer is the same way.They even went as far as to remove the power mixture adjustment from the housings and made it stationary. I would suggest running one mixer starting out and see how it performs. Unless you are running above 5500 rpm alot I think you will like how it performs. Lets say you do have 400 hp, the chances are pretty good that it will not make that kind of power below 5000 rpm. Below that rpm the torque is what moves you over those rocks and ledges. Glad to see you asking questions. There is a lot of misinformation about propane that sometimes causes unnecessary grief. Propane is absolutely the most simple and trouble free fuel system there is for off-road use especially for the money and it is a clean domestic fuel. [/QUOTE]
