tuners' advice wanted.....meth injection ...should i or not?

[NickJRE]

I don't want to get into any debates but, I'd use Methanol Injection on my personal vehicle I most likely will in my Turbo Fox body build at some point.

This is Exactly the type of Poison information that runs rampent through the internet.

As stated it was and EXTREME CASE

Water Meth should not ever hit the rotors as a Liquid it should be a gas by the time it hits the rotors in which case it would never be a problem.

Think about all the blowers out there that have Carburetors on top of them!

Should all those people remove they're carburetors because gasoline which has Ethanol in it is going through the Rotors.

Guys, Please, Lets Not over react to a Picture with No full explanation.

Also guys I would not get bend out of shape because your supercharger company will deny the warranty on it if you run meth. I mean...lets face it the minute you slap a supercharger on your Camaro GM will deny your warranty on the car.

FWIW, methanol does not corrode anything while its spraying. Anyone who says otherwise does not understand methanol and how it works. Methanol will corrode certain materials such as aluminum or certain rubber types...but ONLY when the methanol is sitting. For example, methanol will corrode an aluminum tank because the methanol is sitting and and has time for the chemical reaction to take place. methanol that goes throught the supercharger is not going to corrode your engine or supercharger. It will simply pass through and then evaporate/burn, etc.

Having said that, I am simply correcting some mis-information. **IF** you have a case where ceramic coating or teflon or some other coating on rotors was removed (and again, this is a big if), it has nothing to do with methanol being corrossive.

My first post.

What I have found is that the location of the nozzles are critical. The further upstream the better, since the liquid has more time to evaporate before hitting the rotors of the blower. I believe that it is not corrosion but cavitation (vaporization) that creates the damage that is observed.

I have seen the coating lifted on the rotors of a 112. In this case the nozzle was within inches of the rotors.

Thanks for your first post and good info. Makes sense.

Sorry not sure how I missed your question. Here are a few pics of my Snow mount with trunk pump and tank mount. The safety solenoid and others smaller items are mounted under the hood wiper cowl. The Boost and Meth flow guages as well as all LED warning indicators are mounted in my console.
Hope you like the pics.

Am I the only one concerned about a trunk mounted non-crashworthy methanol tank rupture allowing highly flamable liquid into the passenger compartment?

The only thing that could be worse is a N2O bottle in the trunk too.

[CamaroFTW]

It's a 50/50 mix with distilled water and so I don't even think it is highly combustionable. I could be wrong. You could have a head-on with a Semi too and so I am sure no one "plans" to have major accidents.

[Roger Ramjet]

I agree that a 50/50 water methanol solution is MUCH safer. But, I thought straight methanol produced better power results.

Anyone discounting the fire possibility of pure methanol has never seen a sprint car fire. You may live through the crash but wish you hadn't.

[CamaroFTW]

I don't know of anyone using straight methanol and it is not even necessary. Methanol/H2O mix is to cool the intake air temp on a supercharger and running 100% is not going to give you any more appreciable power. This is not a fluid you burn but a fluid to cool with. I am not an expert on this but my best explanation.

Meth when mixed with water will not be flamable and there is NO issue. The same can be said for NO2. Short of the tank exploading base on pressure, which is highly unlikely to happen if you have a pressure release valve built in, nitrous in the atmosphere Will Not promote an explosion. It only does that under serious cylinder presure

In short you are safe

Pure meth if ignitied will def be an invisible nightmare

I know people that ran 100% & 70/30..
If it makes more might depend more on setup. Meth does cool intake but water cools a little better. Meth gives u more octane where water doesn't. Now the reason to run 50/50 is really safety. Meth has a flash point of 80 degrees which makes it very unsafe. Water raises that. U really don't want Meth vapors to fill trunk on hot day then a spark happens & boom..
