i got my alky installed.
And since i ain''t in the USA, i got a qeustion
Meth= methanol
Alky = ethanol
What is exactly the differnce in using those 2?
if you start to tune , would it be wise to start with 50% water/50% meth?
straight meth?
Thanks
Well, I've run both denatured alky and methanol. Denatured is mostly ethanol with some methanol mixed in (which is why they call it "de"natured). I've been able to run 26psi on both, they have very similar cooling characteristics, but the biggest difference is price. The denatured in the states runs about 10-14 per gallon. The methanol is about $2-4 per gallon. Denatured also has a pretty bad smell to it, where methanol is virtually odorless. That's nice for setups like mine where the alky container is inside the cabin.
As far as tuning, you're best bet is to just go 100%, with no water. But it all depends on what you're shooting for. I could get about 22psi out of a 50/50 mix, but 26 psi on a 100% setup. My AFR is really rich, which is left to my tuning, but it seems to yield the best results.
