is anyone here using an alcohol injection kit on their forced induction? How well does it work? how much boost were you running before/after on same octane gas? how much did it cost? Thanks.

I can't speak for anyone with V8's, but I know a lot of the Turbo Buick guys were able to increase the boost from around 16-17 psi to somewhere in the vicinity of 21-23 psi, sometimes even more. A lot of it depends on the efficiency of the turbo at those boost levels.
SMC sells a pretty good kit. It's $350. www.smcenterprises.com

 

yeah, i've been over on the TurboBuick message board and was wondering if there were any F-Bodys running an alcohol injection. also wasn't sure if the SMC kit was built for the GNs or if it was universal.

 

The only thing you have to worry about is the alcohold drying out your seals. If you run SVT FFV(ford stuff) injectors then you can run alcohol/gas or any mix thereof. As long as the computer is reading O2 then it will continue to dump fuel. Unfortunately our computers don't. You'd definately need a stand alone system. Just remember that Alcohol cuts the AFR in half.

 

I think I confused you, ATO. I'm not talking about burning alcohol. An alcohol injection kit injects an alcohol/water mixture into the air stream at a high psi for atomization to cool down the air. it's like running an extra intercooler that works extremely well. you can use regular Isoprophyl alcohol(rubbing alcohol). they use them a lot on the turbo buicks and TTA, but just wondering if any v8s are using them. I think Willie might be? not sure. just trying to get opinions.

 

Oh well in that case. I don't know about forced induction, but I've seen people fill the washer bottle full of water and use a really small hose or restirctor and run that into a vacuum port. Works like a charm. I guess if you wanted to do it real cheap you could hook up the sprayer to a port in the intake and just pump it in when you wanted.

 

You only want it spraying under boost...

For that to work you'd have to run a hose from the manifold to the tank to pressurize the tank and then another from the tank to the nossle in front of the compressor, and then it would work on the pressure differential.

You'd also want to put a check valve in the line from the manifold and a blead, so vacuum doesn't reverse the flow and so it doesn't start right as you start having boost, but instead at a few psi of boost. You'd also in a perfect world want to mount the tank lower then the nossle so that you don't end up siphoning out the tank and hydrolocking the engine.

People have used these setups with turbos for years, but may have problems with compressor wheel wear from the water hitting the vanes while they're spinning at 100krpm...

 

I've run lotsa kits, even built my own, the smc kit is worth the money. Works great with high boost levels, I've run 18 lbs of boost on an intercooled procharger with alcohol injection and 92 octane.
