so I have a 4mil dune poted by FAST. I am running 28mm pwk with a k&n in an open air box( no lid), pipes are t5's. I know there is more power to be had with this motor. How much can I gain by going to 33mm carbs and better pipes like cpi, shearer, r2's ect. I figure its going to be about 1k with carbs, intakes, pods and pipes. Will it make a big enough diffrence to be worth it?
