Water methanol injection
« on: March 12, 2013, 03:01:31 PM »
Hi guys has anybody on this forum tried the water methanol injection when the compression ratio of an engine you built turned out to high? I used almost all the parts that I had laying around and had bartered for over the years to come up with a combo that has ended up with a 14 to 1 compression ratio. (no its not an FE) Its a 466 BBF. I have already bought a snow performance water/meth injection setup and am planning on trying it out when I dyno this thing in the very near future. Just wondering as on the forums I use hardly anybody even talks about using it. I suppose they do on the more modern mod motor and brand X forums but not much on here or the BBF forums. I have a tunnel ram and have installed a noozle in each end of the plenum. Snow says it will boost octane enough for me to run 93 with this compression ratio. I guess I will see but if there is any interest I will post the results after the dyno time.

The guys on the LSR forum have a subsection on just this topic here: http://www.landracing.com/forum/index.php?board=26.0  Good luck!

Phil, I tried one of the Snow performance systems on my supercharged engine with good results, but I've never tried it on a naturally aspirated engine.  I think we'd certainly be interested in your dyno results with the water/methanol injection once you have them; please post them here.  Thanks, Jay

I will definitely do that as if it works on my engine it should work on anything else.  :)

I too had excellent results with the Snow kit on a supercharged efi set-up.  The Snow kits appear to be well thought out and I will bet you will be thrilled with the results.  My kit out of the box made the car run rich, and all I had to do was lean out the mixture.  An O2 sensor will make tuning a breeze.

I can run 15 psi boost on top of 9.5 : 1 compression (about the same as a 15.5 :1 compression N/A engine) and use 93 octane without any trouble.  In the end I went faster on pump gas + meth/water than on race gas (10.70 @ 128 in street trim).

We use them on our turbo'ed truck and tractor pull diesel engines.  At over 200psi boost we've seen over 5 gallons used per pull. They work great!
