I am looking at a snow performnace kit for a gas motor and wondered if anyone had used one?
 
I've poured water in the carb to clean out deposits if that means anything.
 
What do you have done to the motor? I haven't used them, but I have a few friends who have with good results. One was running turbocharged 462 Pontiac and it worked out great for him. Another was running a 402 stroker LS1 and he was having crazy detonation issues on pump gas. Now he can run pump gas with no issues after the meth injection.
 
It does work, if you advance timing accordingly. I'm putting/put an m112 on my 5.8 in the bronco and have a progressive snow kit on my dodge that I though about putting in the bronco...the problem though is that unlike a turbocharger or centrifugal blower, an eaton is always making boost and would always be sucking up a bunch of meth/water. It would literally take at least a 15 gallon tank to last an entire race, and if it ran out or something malfunctioned and you were still running advanced timing...there goes another motor. The other thing--and this might be iffy--but ECORS doesn't allow "alcohol fuels" in any vehicle. Would definitely be up to R&R as to how they define that though. You can run a fair amount of boost on an l67 before needing meth or intercooling though.
 
Braxton, I'm running a l32 now.(still need you motor for another project) and have been told the gen v blower will need an intercooler or bunch of mods to run my 3.5 pulley, 3.7 os what I need. Guess I will order a bigger pulley for now.
 
I ran it on my old 4runner. It was cool being a chemical intercooler but the thought of running high boost and something malfunctioning in the water meth system scared me a bit. I ended up not running it and running a more conservative tune and a better intercooler.
A water/air intercooler is where I would start if you can make it work. A air/air wont work well for us.
 
The intercooler setup for these are water over air and I was trying to avoid another raditor and pump fan etc etc...
 
I definitely understand but they are more efficient and if you pack an air/air full of mud its not going to do a whole lot and you'll be back here again, plus it needs to be in direct airflow. You can put a water/air anywhere almost.
 
It has to be a water/air intercooler, it's an eaton blower that sits on top of an intake manifold. The kits that I've seen sold to retrofit use the same pumps for circulation as the factory cobras do so I wouldn't be too worried about that, just all the extra weight. How much money is 30hp worth? You can do the same running race gas and having it tuned for the high temps.
 
Water/meth works great in certain apps. as stated above and the snow performance kits are very good. That being said, I would have to agree with the others that a liquid/air intercooler would be the way to go in this case. If you want to run an A/C compressor and condesor, a super chiller would work even better!
