[Diy_efi] Water metanol turbo assist

Fuel has density, yes.  But if I am the one that is really dense,
someone 'hammer' me.

1.25 ml. of fuel to ONLY .625 ml. H2O.  Does it matter if it is
I bucket of water to 2 buckets of fuel?  :)  It is still 50% right?  
That is a hell of a lot of water to throw in the mix, no?  I've got
the hammer waiting, just in case.
