prechambers mods?
Well, i'm definably going to try this. Thinking about a 20~30% bigger holes. It's for a om606 which I want to push 500hp. Also going to flow the head one of these days. I'm curious about the result. However I think I never get to notice it since I've never driven the stock pre chambers.
Edit, How about drilling one hole straight down?
