N2O options?

84_GT350 · 01-18-2001, 03:43 PM

Ok...this is just me looking ahead for my project. I just bought a new car so I'm putting an injected aluminum headed stroker motor in the Mustang during the summer. It'll run between 375-400hp NA and I'm looking for about 125hp or so worth of N2O (did I mention I'll have a main girdle?). Should I get a dry system or go with a wet system? I'll be using at least a 190lph fuel pump with (probably) 30lb injectors with a programable DFI system. Wet systems always seemed more complex but have the safety factor of adding fuel with the nitrous. Although, i'm aware of that fuel's capability to puddle in the manifold, so a plate system is the only option there. Dry systems seem easier to hook up but will my fuel system be able to hold up? Being the enormous f!@king geek that I am, I've read up as much as I can about it (and I work in a book/music store, so that's a lot of stuff) so I know all the theory and whatnot. I also know that a bottle warmer, pressure gauge, and remote valve opener are mandatory. On a sidenote, anyone know where you can get one of those arming switch panels like they used in "Gone In 60 Seconds"? You know, the one with the covered toggle switch and the LED light marked "armed"? That thing looked bad@ss.

Personally, I don't trust the dry systems, mostly because I don't like having to depend on the regulator and injectors for the extra fuel. Failure of diaphragm regulators is fairly common, and injectors don't always flow evenly. Plus, the dry kits deliver fuel by spiking the fuel pressure. That inceases the odds of an injector sticking.

Puddling shouldn't be a problem if you activate the n2o only when the RPM's are up to 2500-3000 rpm. Then the intake air velocity is high enough to carry the mixture through the intake.

If you're looking for a plate system, we already carry them for the GT-40, Edelbrock, and Holley intakes. TFS will be available soon.

As for that switch in the movie, that's an aircraft switch cover. They fit on any shaft mounted toggle switch. They're about $25, and are sold seperately from the toggle switch.

So what happens when the transmission shifts and it puts me below 2500rpm? Do I have a problem then? Also, as for the switch cover, can you get them with the word "nitrous" embossed like that? If so, where?
