Tom, you've got guys down there that make way more power than I do, so i'd think they'd be more knowledgeable. Crush is reeeaaaly fast down the straight..he's making lot's of ponies.

I checked the site out...different dynos make different numbers. Looks like you're on a dynojet, not known for conservative numbers.

So, what's the exhaust set up? The standard advice is to tune the carb for power and note the A/F ratio, as well as the EGT, then use EGT readings at the track to compensate for weather.

How do you know when you're engine is in need of seals? They say it's when it cranks a lot before catching on start up. But they also say they are fastest right before they blow.

Remember the basics. keep the carb cool, keep the engine cooldraw fresh air, not superheated air. And the exhaust has a large role in power production as well.
