that is common knowlege on the previous 11 sec passes but what you didnt post is the mph these 11 sec STOCK viper passes are at. I would say between 117-120 tops!!! at least for the gen 2 11 sec passes stock. snakester is at the same time at 10 mph over these guys passes. thats hugh when your talking mph. a 150 shot should be throwing a bad driver into low 11's easy if you hit the nitrous in every gear. even on stock rubber. i do it all the time on kuhmos running 11.2 at 130 all day long with only 2.0 60 foot times cause im not banging nos off the line but am using it to pull me through 1st, 2nd, 3rd, and the just hitting 4th going through the traps!!!!snakesteri am not saying that you are a bad driver at all, just that your system is not performing like it should and before you do any damage, please get this thing worked out. oh and reviewing snakesters last post, a nitrous express kit is designed to give the intended shot used to the wheels, so your 150 shot should give you 600hp to the rubber not what your seeing. torgue should hit mid 600 easy!!!. did you ever dyno with air fuel, you are not setup right. ask any experienced nitrous guy before its too late.
