Any tips at all?
I am kind of in the dark as to where I should start. Are my current thoughts on track or way off?
Based on my reading from multiple sources I've developed the following parameters:
10% of water/methonal to fuel minimum to reduce octane requirement.
25% maximum to stay out of combustion quench.
I've got one reply that says 10% may not be enough so I decided to check into things some more. One tuner for my car stated that an 11:1 fuel ratio should be able to run 4psi without detonation on 87 octane. Of course not as safe, but it would work. So I ran some numbers:
2260kJ of heat absorbed by water
1109kJ of heat absorbed by methanol
50/50 mix = 1685kJ
350kJ of heat absorbed by gasoline
1685/350 = about 4.8 times the latent heat aborbing ability
12.8 to 11 is a 14% increase in fuel
same results obtained through 3% increase in water/methonal
I'd say 10% is more than safe, if anything I should be able to go with less.
I am no expert though, I need to know if I am on the right track from the pros here.
