I run a 15 to 1 race engine which is a whole lot more trouble than a stock engine would be. Alcohol does take more maintance. But it can pick you up as much as 3 tenths and is more consistant et wise at the track. But if I run everything because is was easier I'd be racing my tow vechile. But thats what makes racing so fun. Everyone has something different, no two cars are the same.
