Question Propane Injection

Can propane injection such as used on diesel engines in the USA be used as a cheap way to add power to a modern turbocharged gasoline engine?

I read that the octane rating of propane is 110. Is that correct? Would that be enough to enhance performance significantly?

Are there any beneficial (better burn, cleaner engine) or detrimental side effects to using propane injection?

why not just go the whole hog and do a full camping gas conversion to a skyline... LPG is cheaper than SUL!!!

what difference would you notice on LPG? the marketing types down this way think that the stuff is the way forwards...

It is used instead of water injection to help stop det.

I was under the impression that Methanol was used along with water injection systems

Yes WI usually has methanol mixed in, but some people simply use propane injection as a more effective (apparently) alternative.
