How does the SMC pump respond to using washer fluid? It's cheap, is 50% water and 50% methanol right? About 99 cents per gallon. Is the pump succeptable to rust or corrosion?
its pretty much 50% water, 50% of some form of alcohol, and like a drip of blue dye...check a bottle, you'll see...Lots of people use washer fluid for water injection...fairly common.
i have been using straight 100% denatured alcohol and i haven't had issues really...just had my boost too high...now running 22 psi safely and no knock whatsoever...sometimes i can get up to 25 lbs of boost with no knock but i have to really gradually get into it...i can't mash the pedal down like i can with 22 psi without major transitional knock...
I have been running 50/50 water/ethanol. I haven't gone to 100% ethanol becuase I worry about flammabilty. I have also read that the there isn't a benefit to running greater than 50% (Anybody that's tried both know for sure?)
Also, I found an MSDS for washer fluid. The methanol was 35% -not bad for $1. I'm more concerned about the blue dye. It leaves crusties on my washer fliud bottle. What's it do in the turbo?
One thing about ethanol. It's difficult to seperate from water. That may be why it's $8/gallon. They are trying the purify it, and then some of us go and dilute it.
If we could find a source of "wet" ethanol, it should be very cheap and "pre-mixed".
