Actual nitrous kit on a 212 predator

[bbrewer2005]

Ok so I've played with the 6 sigma nitrous kit that uses the little whippet cartridges. They last about 2 hits and it is a pain in the rear to switch them out every pass.
I've got a race car and enough extra nitrous stuff to put an actual dry fogger on it.

My issue is jet size. By my calculations, I'd need a .007in jet for a 2hp shot. They aren't made. Has anyone ever filled a jet with solder and used a micro bit to make their own custom jet size? A 2.5lb bottle would last forever instead of changing cartridges after a 6-8 second burst.

Wouldn't a dry fogger mean no fuel jet in the nitrous system? Isn't that why it is called dry?
If you're using it for drag racing (I assume you are since you say you switch em out every pass), why don't you just keep it a dry system and increase the main jet size?

On an actual racing nitrous system, the nitrous is injected as a liquid, regulated by a jet at the injection point. The little go kart systems seem to regulate the flow in the device itself, and just let the evaporated gas flow down the tube to the intake.

Do you have access to a micro lathe? I would bet the jet size on one of those little cheap brass plumbers blowtorches isn't far off from what you'd need, if you have a way to turn it down to size and thread it.

I guess I misread the original post. I thought he was asking about a fuel jet for the nitrous system, which would make it a Wet system. My mistake.

Why not just fashion some larger bottles? Or, build an adapter bottle that connects their button dispenser to your larger bottle. Perhaps even use on of those CO2 shifter bottles.

Anywhoo...

Folks have soldered carb jets and redrilled them, works fine. I don't see why it wouldn't work on a nitrous jet, except maybe because of the pressure?

That and 7 thou is a pretty dang small drill bit

i ran 35% nitro in a clone and it lived for a while. I'd set it up wet and hit it hard, but that's just how i roll.

Thanks for all the replies. I like the idea that TT540 has. I could probably have a machine shop make me an adapter cap with a -4 an line. I just need to check on the pressure of those little cartridges. Actual nitrous bottles typically run 900-1050psi. If those cartridges are less then that, that may be a problem.

Use the 0.009" and let 'er rip. LOL.
I think the whippets are around 700 psi from what I could tell from my research.
