Noobie to nitrous looking for any tips on not blowing anything up!!



I was at the store to buy the tap I need for the fogger nozzle and everywhere I read it says 1/16th but that doesn't seem right that's so small and my nozzle is more like 1/8. But it is there standard fogger nozzle not some special one

Yeah, I'm pretty sure they are 1/8 not.

Find the actual diameter of the orifice in the jet, and add 15% to it. That should get you close.
 
Ok well anyway I just went on the holley website and they have a 1/16 npt pipe tap listed in their products as the tap required for all nos fogger nozzles and then it says to use 1/4" drill bit to start. So I have no idea, I guess "npt pipe taps" must work off a different sizing scale then standard drill bits.

it's definitely 1/8th npt, and use a 21/64 size drill bit to drill the hole or something really close to that size.

I looked it up an apparently a 1/16 npt pipe tap is 6.25mm which is just under a 1/4". I have no idea why its called a 1/16th but that is the correct size. Nos/Holley emailed back and said they couldn't advice me on jet usage for e54 but with them only costing 6$ I'm just going to buy 10 of them and ill have a good setup somewhere in that mix
