Flaw in Alcohol Kits?
#31
Oh the buick boys ......mmmmmm been there done that almost 20 years ago.
I used water injection in 1979 on a 351 cleavand with a 12.5 to 1 motor to help with
detonation. Back then the car ran 11.90
But saftey should be first...

I do like your idea of the 50/50 and would be interested to know what the highest non flammable percentage of Alcohol to water would be and what the percentage power trade off might be compared with straight alcohol. Anyone know?

BTW - I have been told that windshield washer fluid can burn also - but did not get around to testing it yet

Other alcohols will vary in flashpoint and will vary in flammable concentrations with water. Denatured alcohol can be comprised of any of many different mixes of adulterants, and I wouldn't care to use it. Some of the denaturing compounds may actually reduce fuel octane, so be advised.

It takes twice as much alcohol to remove then same heat as straight water, but alcohol adds fuel.
The best compromise is a 50/50 mix of water/alcohol or methanol. That's why I went with the system I have.
Coolingmist.com. $280, with water pressure indicator, blocked injector indicator, low fluid level indicator, simple install, used IC spray tank, install took about 3 hrs. I love it.
I run DISTILLED water(not tap) and mix with 20 below washer fluid.
22psi of boost, afr 12.2:1, 22 deg of timing on 91 OCTANE with no knock!

The biggest benefits of alcohol/water injection are not simply to add a higher octane substance. The addition of water to alcohol improves detonation control beyond what's possible from injecting pure alcohol alone.
This is because water absorbs more heat and effectively cools the air charge. This is why water alone is effective at inhibiting preignition. When coupled with methanol, the combined effect is greater than either alone. A 50/50 mixture is a great starting point, and possibly the endpoint as well.
BTW, methanol is clearly the best alcohol for this purpose.

But you said,
"I disagree that staight alcohol is not as effective as a mix. The staright alcohol will always be slightly more effective than a mox with water as its a fuel and burns - unlike water."

I just threw a match in my Pep Boys washer fluid. I need new eyebrows.
Match went out.
Can we test it on beer? Beer is good. It's plentiful too.
Which brings to question, if we run alcohol in the reservoir and it has a vent, would that constitute driving with an open container?

Here's a little something which should be beneficial to those who are interested. It comes from a reference entitled,"The High-Speed Internal Combustion Engine" by Sir Harry Ricardo.
