Re: Water/methanol injection? (JACSZ06)
About methanol, never used water injection...
First of all the drawbacks: it would take major modificatoins to the C5 to make it Methanol compatible. Methanol eats through normal fuel lines, it eats through aluminum. Only a few cars on the market have fuel pumps compatible with methanol (seen those flex fuel badges on the back of some Fords? those are compatible have used them out of I think it was a Taurus) You also have to way richen he system as it takes alot of methanol compared to gas (almost double).
The advantages of methanol is its heat of vaporization. When it is sprayed out of the injectors it gets cold. We used M85 (15 percent gasoline 85 percent methanol which is safer because you can see it burn unlike pure methanol) at school in our turbo charged race cars. With M85 there was no need for a intercooler because the methanol cooled the incoming charge. Also methanol likes high compression. We were running 7-9psi of boost on an 11:1 compression engine.
However my last year of school we went the non-turbo charged route and determined there was no advantage to methanol if we were not boosting and used gas.
