I will likely be doing a water/meth injection kit in the near future...

Why is methanol the alcohol fuel of choice? Has anyone ran any other types alcohol fuels?

 

Bumpin this post before I go to bed so hopefully I get a reply by tomorrow. Im kinda looking for a scientific explanation for this, I slept through chem last fall otherwise maybe I wouldn't have to ask. Thanks

 

Spend a few minutes searching DTR or googling methanol + racing fuel, then we can answer any remaining questions... right now it'd take too long to type everything you want to know.

Yes, other fuels have been injected.

 

Sorry, I will try a search on google, get too much to read on a search here. I was wonfering why longer chains arent used as often as meth

 

Long chains? Like cetane or something?

CH3OH (methanol) has a large cooling effect due to it's high latent heat of evaporization, and is relatively cheap and readily available.

 

i have no idea what u just said

 

It absorbs a lot of heat when it changes state (from a liquid to a gas)...

 

Hey xlr8r, do you happen to know the mixes on wwantifreeze? Like how much meth is mixed in the -40 stuff or the -35 stuff?

thanks

It varies between types/temp ranges - I don't believe it's anywhere near 50%.

I seem to remember the pump OEM saying that running non-denatured alchohol shortens the pumps' MTBF (and that the WW fluid doesn't have denatured). Too busy to look it up right now, but I remember posting on it last year.

 

Have you ever put some regular rubbing alcohol on your hand it is always cold. This is the same principle with methanol its got a cooling effect and combusts with the fuel to give you more power but burns cooler at the same time so you get the egt drop. Thats also why alot of the sick race cars run alcohol instead of pump gas as fuel the cooling effect and more power.

 

I think its mostly due to running high compression (the race car thing), but the cooling effect is still nice
