I have twin 67 mm turbos on my 400 sb chevy that see some street and some track use ,and I wanted to know which would work best with my setup?

thanks for your help

 

everyone in the threads here says 50%water 50%meth. mix
some are saying just use regular windsheild washer fluid its premixed.
i will look at the washer fluid ingredients next time i go buy it.

 

Straight Methanol works best and some are running over 40 psi boost with pump gas / 100% Meth. With water/air, you won't be able to run over 15 - 18 psi boost, but at least you don't have to fill the Methanol tank.

I have both.
