My old engine on gas wouldn't run below 230. My new engine on alky wont run above 180. You don't need to be a rocket surgeon to figure out which one your gonna get more out of. Not bad for a few hundred bucks of injectors and a fuel management program. Nothing needs to be done inside the engine. You can have aftermarket bolt ons and stock internals and tech pretty easily (right DAD?)

If you don't have the time to clean out your fuel lines you shouldn't be racing cars. What other basic maintenance are you overlooking? These things are fast and dangerous so if you aren't fully dedicated to it then don't put it out there with people that are. That's putting your driver and the other drivers in a bad position.

Are costs out of control? Not compared to three years ago with open engine rules. Are they higher than they need to be? Probably. Are the cars still the best bang for the buck in dirt racing? Definitely.
