So guys I did a little research on this topic!! I went onto the Snow Performance forum and the technicians from SP recommended not using propane and W/M together because they have similar burning properties. They recommended if you do use propane use only 25% methanol to water at most but highly recommended 0% methanol if propane is used.
I also read about a common rail Cummins making massive gains using the combination of WM and nitrous oxide. I already have the WM injection kit so maybe someday I'll try some nitrous!! I haven't heard of anybody else puttin N2O on an idi, so maybe I'll see what it can do to my 7.3. I'll just be sure to have headstuds on first for sure. But I think the combination of drugs will get me close to 400 horsepower depending on the size of the nitrous shot and amount of extra fuel from the Moose Pump I'm gettin real soon. What do u think? And is there anyway to make a main stud girdle for these motors cus isn't that amount of power pushing the threshhold of what these motors can handle before they start to flex?
