I knew this was a performance modification done on diesel engines, but a compression ignition engine (diesel) and a spark ignition engine (Gasoline) are much different. The Propane isn't going to do anything fo rhte gasoline enigne is it? Its called nitrous, kind of like the propane thing except for a spark ignition engine. Note, this post is inspired by a possible group purchase that is listed in the MN-12 nationals info and I just want to know if there are propane kits for gas motors anywhere, regardless of the make of car. Why do this when you can just use nitrous? You are going for the same effect, a power adder that is there only when you want it.
