I have seen many NOS set-ups, I would be interested in one, but I have heard they are terrible for your engines, even the dry shots. Can owners let me know what they think, mine is an everyday driver, so I would need medium, like a 50 shot, hard to keep cool, hot? Also is it illegal? Sorry for all the newb questions, I appreciate all the help!

 

any FI is terrible for your engine. i believe you can have one for a everyday driver but don't use it everyday

 

If I'm not mistaken a wet shot is a lot better for your engine than a dry shot. If you set it to spray @ WOT, and had a toggle switch to turn the feature off when you didn't need it, and ran say a 50 shot, I'd imagine you'd be okay. As far as longevity...wait till someone who's actually done it answers

EDIT: I don't think nitrous is Forced Induction ^

 

- that does not make any sense.... dry shot setups are the WORST...

 

Nitrous is still forced induction, its just chemical instead of mechanical.

I stand corrected then, I knew it was considered simulated displacement, but didn't know it was considered FI.

 

- I wouldn't worry about a 50 shot, should be fine.. just get a wet kit..
- I like NOS, not these 'newer' companies... but I suppose its all personal preference...
- oh yea, it IS illegal...

 

for all intents and purposes, i dont think NO2 counts as FI. IMHO

 

Nitrous oxide is not forced induction. There is nothing being forced. Turbochargers and superchargers force air into the cylinder, in essence increasing a cylinder's volumetric efficiency. Nitrous oxide simply has a higher oxygen content; it is NOT forced induction. It increases cylinder pressures, yes, but that's it.

It's a common misconception that nitrous oxide blows up engines. It does not. It's not even flammable. Yes, if you spray a 150 dry shot, you'll likely melt your pistons due to an overly lean mixture, but if you do it properly, nitrous oxide is perfectly safe and a great power adder.

 

No, FI is not terrible for your engine. Of course, I'm speaking strictly about properly setup engines. Many would argue that 9000rpm is not safe for a production large-displacement (relatively), large-bore engine. But just look at all the S2000s at track days, where you stay in VTEC for 30min at a time, if not more. Setup and tune it properly, and it's just as reliable as anything else. Slap it together shadetree style and you're likely to grenade your engine. When you put 9 volts through a 3v flashlight, and it self destructs, do you blame the hardware, or the operator?

If FI was terrible for engines, then everything would be normally aspirated.
