Snow Performance water/meth injection kit

We were curious to see if a Snow Performance water/methanol injection kit would give us anything on a 10.5:1 compression street engine--so we dyno tested it!

Back in our August 2011 issue, we installed and dyno tested a Snow Performance water/methanol injection kit on a 12:1 compression 392ci Windsor. On that pump-gas challenged engine, the Snow kit allowed the full measure of ignition timing--formerly reserved for just when race gas was in the tank. The result was an extra 50 hp over the pump gas tune--and this engine wasn't even boosted. So we wondered, how much would it be worth on an engine with pump-gas compression?

We decided to try Snow's Stage 2 Muscle Car kit (the same one used for the earlier Mustang test) on our 1968 Nova project car. With octane tolerance not being a part of the equation, any gain we'd get would be strictly related to the cooling properties of the water/methanol solution. (We didn't change the ignition timing between tests). Want to know what we picked up on the dyno? You'll have to check out the video here, or wait to read the full story in the July 2013 issue of PHR.
