that gives me an inspiration. i've seen racing lawnmowers, which are a lot of fun, but racing forklifts....now there's an idea!
how about a high-winding coventry-climax 4-banger, putting out 350 horsepower at 10,500 rpm on propane! mount it in a chopped/channeled/sectioned forklift with racing solid rubber tires and set up a track inside a warehouse, then look out!!
..........or, wait, did i get off the subject, here?
