Re: Permanent 300 Six Cyl Head CFM solutions- A Work in Progress

Water/meth injection works great. Until it doesn't. Paul has warned me about the higher CR of the Jr vs a carb'd head. IIRC, he said it should produce something around 10:1 CR. I'm fairly confident that the build won't depend on WI to prevent detonation. It's neither "full race" or tracto...

Re: Permanent 300 Six Cyl Head CFM solutions- A Work in Progress

I ran a primitive form of water/meth "injection" in the past.

This time I'm going to be running modern high pressure water misting injection. I'm not overly concerned with more compression, detonation or knock.
