Quote: How would meth injection play in this? Would spending the $500 or so on a Snow or Devil's kit pay off in the long run?
I run a snow system on my 408 blower application. I run 110 race gas, with boost pressures in the 15 - 18 lb range. I can't remember what that equates to in CR, but I think it was in the 14 - 16.1 CR range. My motor build is 8.7:1. I was told I didn't need it with 110 race gas, but I was uncomfortable with those boost #'s, plus I wanted to be able to run Higher boost numbers by changing blower pulley sizes when I wanted to ( my Snow system is adjustable). Don't think I would build an NA motor around using water / meth injection though. I looked at it as more of a safety thing ( staying out of detonation ), but I guess you could also look at it from a HP standpoint if you wanted to include it in your build. It does give you some flexibility, but it also has some diminishing returns. You can only add so much before you can't keep the candles lit.
