the answer to this question depends on what you're running... if it's not a top line engine that's getting over 10 minutes per tank, maybe do it. Personally, I would never touch any engine we run with a dremel. With the CNC technology available today, everything that can be done to the engines to make them faster is pretty much being done. The engine designers/testers spend their lives trying to get the engine exactly perfect, and the notion that some guy in another shop somewhere is going to make the engine better than say Andrea Rossi or Adrien Bertien is pretty silly. flame suit on...
