good question cause i think by the end of the race season this year i`ll be going to injection and putting my 1050`s on the shelf.but i need to do some homework cause i have no idea about this alky injection stuff.but i do know i need to up my compression and probably a cam swap.But i dont want to have to change my oil at the races.Someone told me evac system helps keep the oil from being milky.My uncle had to big of carbs on his jet boat and it would screw his oil up enough that it cost him 2 motors before he up the compression.cant wait to hear some responses.sorry if i kind of jacked your thread.Tom
