we put the nozzles in the velocity stacks and they are pointing right down the throats of the carbs. it worked great for us, the only thing i reccomend is putting the "t" outside the air box, we put it inside and it came loose or didnt get tighened all the way or whatever, it came loose and a vector cant take a main feed line shot of nitrous! it was fast as hell for 2 runs and then the little bugger started breaking the tops off of pistons. oh well lesson learned.
