But my eclipse is soon to be running and I might want to run it strictly on race fuel, Im more concerned if it would help or make things worse to run it like that?

That's a myth, higher octane gas does not clean anything. However E85 would. Or you can simply put in injector cleaner, which is a form of alcohol.
With no changes, your factory computer will not see knock as much if at all and allow you to run maximum factory timing, which makes some power, but really no better than 92 octane. The real benefit is you can turn up the boost with race gas without knock, that's where the power comes from. If you have a full standalone, you can do a lot more to increase power. Since mine has turned into a weekend car, I've been running nothing less than 100 octane unleaded on the street for years. Now with E85 and being able to tune for that, that's my new soup de jour. Race gas for cheap. It requires a lot of mods to run it properly though.
