Below you can see where I mounted the bottle.

In theory couldn't you simply add ton of fuel and strap your car on a dyno and do multiple WOT runs with NO2 spraying and lean the car out to "safe" AFR's while the NO2 is on?
This is assuming that you have a PFC, WB and a datalogit.

All of the turbocharged engines I've seen that spray nitrous (certainly not any 13B-REWs) do so only in higher gears at WOT, and the shots were pretty conservative for obvious reasons. The cases and cylinder head studs were major oversize units, and the pistons were specially made for the application due to the huge combustion pressures involved. Needless to say, many destroyed engine components littered the path to getting the combination close enough that the engine would live for any decent amount of time. Like that long nitrous essay said, considering the fact that the rotary is sensitive to a/f ratios as is, playing with nitrous when the a/f/ and ignition combination is already fragile is looking for a lot of repair bills.

I really don't see a 50 shot being that serious on the engine, in fact under high pressure at wot it will actually lower the interior temperatures helping in the reduction of detenation, if fuel is accomedated for the increased oxygen molecules. The oxygen atom isn't the issue, the problem is will that drastic reduction in temperature as a result of the nitrogen atoms have a negative effect on an extremely hot rotor and apex seal.

Bringing back from the dead... I was reading through some old posts.
I am the author of that article, Sean Cathcart.
I stated not to use nitrous on a stock turbo. Its perfectly fine to use on an aftermarket turbo, but when writing that article, I generally assumed most people installing an aftermarket turbo didn't really need an explanation on how nitrous works... 4 years later, I have learned otherwise.
I can answer any specific questions anyone might have about running nitrous on their car, turbo or otherwise. PM me with them.
