3FE NOS? (Nitrous)

Cheaper and easier than a turbo or a supercharger or drivetrain swap. Good power increase for the few times I really need it (hills and highways).

But can the computer handle a dry shot? How long does a tank last? How big a shot is enough, when does it become unsafe (in actuality not just speculation)?

a wet kit would be much much safer. as it ca only inject as much as the injectors can put out...

Wet system injects through the factory injectors?

What about a dry system that also fires the cold start injector?

Hmmmm, interesting idea. A slight boost might be enough to augment hill climbs and help with passing. I would imagine if it's not a large shot, it could be held for a longer duration. Maybe something small like a 15-20 HP shot would work. I can't imagine it being too good on the piston rings in any configuration though.

We put it on my built 2f and plenty of V-8s but never on a 3FE. The only issue would be the extra fuel delivery. Before I took it out, I went through bottles pretty quick. Those small sneaky pete bottles don't last very long. A 15 hp shot isn't gonna slap you back in the seat. 50 works good on a tight 2F. If your motor has any issues, don't bother. As far as being a cheap power increase, if you used it in a daily driver as an "extra boost" to climb grades, pass people, etc, then I am pretty sure you will go through quite a bit of nitrous.

I really don't need more power all that often. Mainly on longer trips over interstates with long/steep grades. If the speed limit is <55 then I really never feel a need for more.

I was thinking around a 30 shot, and run 2x 10lb bottles. Do they sell larger bottles? Do filled bottles keep well? I could add a BEGI FMU p.n. 2023 to increase fuel pressure over stock, but this couldn't be 'switched' on and off, could it?
