I was thinking of doing something and wanted to see if anybody has done this or has theory on it. I am building a 383 with the stealth ram injection set up. I was wondering if I run that alcohol injection kit from www.smcenterprises.com would I be able to run like 12:1-12.5:1 compression on the street and still be safe with the timing. I have aluminum heads and fuel injection.

 

I'll be testing water/ alcohol injection on my 12.6:1 iron headed N/A motor this spring.

Shouldn't need a high pressure pump just to spray water down the carb though. But will use a high pressure pump/small misting nozzle if nessessary.

Water/alcohol flow can be as much as 25/30% of the total fuel consumption.

Going to be a lot cheaper than race gas.
Generic "Blue windshield washer fluid" is almost ideal.
It's 60/70% distilled water and 30/40% denatured alcohol.

It's like 1$/gal. The cheap stuff is the best, no detergents.

I built a detonation detecter (ears) as per instructions on
www.autospeed.com using RadioShack parts. easy to do.
Very effective for finding detonation.

 

Do a web search. There are lots of pages about it.
