LOL. im sorry.. all i can do is laugh at the ignorance.. if you dont know.. your slow..
to the OP. having used every nitrous kit made, i can tell you that by far i have made more power, hurt less parts, and been alot faster using WON products. to answer your questions
1) if you cant use a properly tuned direct port system, and are just tryign to fog the box, spray THROUGH the filter.
2) Starting small is fine, but never rely on a rig to make power.. tune it.. its simple with a wet ket
3) id recommend a nos mini. its cheap, and will control 2 channels. when i first started, i tuned the engine, then tuned the nitrous solely with the nos mini timing. (and jets for the wet kit) If you dont have a datalogger already, then go with the NC2 and hook a wideband 2 it.
And if anyone wants to take a bet, Ill take any non won equipped bike, put won parts on it and go faster. ANY BIKE.
BTW folks, i know for a fact half the people the bad mouth trevor and won, and won parts on their rides.. so yeah, take it for what its worth.
