unfortunately with n2o you want no engine wear, it means no n2o. Any time you add a power adder, you increase your engine wear. Engines are rated at horsepower-hours. So the more hp the less hours. :mrgreen:
100 shot occasionally. but due to the split port design, there are 2 runners for every cylinder (12 runners total). the higher the shot, the more likely you are to go lean in the corner cylinders due to the nitrous and fuel not seperating properly and all going into the middle cylinders.
75 shot is safe for all the time, but you can do 100 if you goto the track for a couple runs. i wouldnt do it often though w/o a good tune... (even then i wouldnt do it often on a split port)
as long as its a wet shot, no.. the nitrous is tapped from the fuel pump and the fuel rail. the nitrous and fuel mixture are mixed even before the injectors. the injectors just do the normal amount for the incoming air supplied. the nitrous already has the proper amount of fuel.
you could run a 100 shot on 14#. i just wouldnt suggest it w/o a fuel pump ugrade... people get larger injectors when running nitrous for safety and they will make it run a little rich just in case.
i like those NGK iridium tiped plugs, but anything thats not copper would do, make sure they are a couple degrees colder than stock, get a new fuel pump, a 155 - 255!
that should hold you over for a while
