I have been using my water/ methanol injection kit for over 2 years now. So far I was running on straight methanol with great results. To be honest I never felt comfortable with this idea, I was checking it all the time and I knew that if something goes wrong, it would end to be catastrophic.
A few days ago a modded EVO with methanol was running on the dyno, a few moments later for some reason it caught fire, all fire eXtinguishers ( about 10) did nothing to he fire. It stopped when methanol finished. Thank god nobody was injured.
This was the reason I decided to run a water/methanol mixture in stead of straight methanol.

I was told that the maximum (safe) mixture is 70/30 meth/water. Anything above that is flammable. 70/30 cannot catch fire, even if you light it up.
I'm not sure if this is the case, this is what I was told.

I am running the aquamist HSF3 with the two largest nozzles supplied. I have set it to start at 9:30 (around 0,6b boost) and 5:30 which is the maximum amount sprayed.
From the logs it looks like it needs more than that.

For those who are running same setup, can you please share your settings and thoughts?

Any suggestions?

Thx

 

Antonis, I don't have any experience with methanol sprays but I do know something about methanol. Even a diluted solution consisting of 25% methanol and 75% water is still considered a Class I Flammable mixture. The safest thing to do would be not to run methanol but if you do, you should check your methanol line connections regularly. I don't think it's going to make much difference if you're running 70:30 or 100% methanol if a line breaks or comes lose and sprays methanol over your hot engine. Even the slightest electrical spark (i.e. static electricity) can ignite methanol vapor. Dave

 

Thank you for the information Dave,
I'm just looking for some alternative solutions to minimise chances of disaster
I was thinking of installing stainless lines, but I must pull the engine in order to do that.

Are you sure that 70/30 is still flammable ?

 

Antonis,
maybe it's time for you to get alpha turbos and forget meth?

 

Yes, make sure your lines are installed by someone who really knows what they are doing and periodic checking/maintenence is the key.

I've never tried to ignite a 70/30 mixture but according to that chart, the flash point of a 70/30 mixture is about 17 C, whereas 100% methanol is 12 C. So if I were a betting man, my money would be on it would ignite under the right conditions (it's the methanol vapor above the solution that ignites). 70/30 is probably safer but not to the point where you wouldn't take the exact same precautions as you would with using 100% methanol.

 

Dave,

I have Decited to keep it 100% methanol and make it as safe as possible. I'm in the search of Teflon tubes covered with stainless still (NOS like) with all fittings being T6061 aluminium.
I have found some on the Internet.
What worries me the most is tube leak due to physical or other damage, also mice could damage the nylon tube.

 

I agree. I don't really see 70/30 being a significant safety advantage over 100. Your smart to use stainless steel and teflon. I would also used anodized aluminum if possible. You should be fine, just set some mouse traps up around your car!

 

good idea

 

Does anybody know what CC/min do the stock injectors spray (max)?
I think the injectors supplied in the kit are not enough for my car.
I am running the two largest supplied nozzles 0,9mm and 1,0mm. Also the control unit was set to spray 1:1 IDC but I set it 50% more 1,5:1 (max)

In the instructions of the kit it says straight methanol should be 20-25% of the IDC.

When dataloging Todd said that it would be better if we could spray some more.

When ordering the new still tubes I could order some larger nozzles.

 

i do not know the unit you are useing but in cc unit !!!!

i used 2 550cc nozzles and it was Enough to fixed spark timing !!!

 

100% methanol is destroying aluminium, I heard 50/50 is quite safe.

 

Thx for the info

 

Who said that methanol destroys aluminium? I've never heard of this. If this is the case then 50/50 will also destroy the aluminium since when the mixture enters into the engine it separates. This what I've read.
I did some tests with methanol, the only material I found that gets destroyed is plastic
