In a honda it goes.....dizzy #4 #3 #2 #1....so it would hit number one first unless you had the nozzle pointed directly to #4 cylinder. If you look at the way air flows in an intake manifold it will flow easier to cylinder one. I am just saying this because if you take any STOCK block/pistons and do a compression test after running a few 75 shots bottles through it you will see a semi lower compression in cylinder 1 then 2 then 3 then 4 working its way up. This tells me that more nitrous is entering cylinder one then any other cylinder therefore burning up the rings quicker.
