How much horsepower before pushing water? Trying to get a ball park figure, I know detonation greatly affects the ability of the engine to stay sealed.

Thanks guys.

I'm no expert, but I'd like to think you'd be well beyond 1k.

I hope so but don't have any real knowledge or experience.

12-1300 at the tires is doable, use good fuel and dont get too aggressive with the timing and you shouldn't have any issues. Its more of an issue of tuning then anything else, if you just tune your stuff as a hobby i suggest getting someone with years of experience that does it for a living to tune it, especially if you are investing a large amount of money into the motor.

It's mostly up to tune and octain. We've pushed 1200 on stock size studs no problem.

Slowhawk are you referring to any kind of uncontrolled combustion?
