before I spray my car on the track I want to tune my n2o setup on a dyno to make sure its right. The best way to do this is to tune with the fuel jets right?
also, does anyone know where i can get the jets i may need todo this?

 

Good idea.

Tuning with the fuel jets probably makes sense, though I don't see it as critical. But you could pick the HP you want by the nitrous jet size, then tweak fuel jets until you're happy. Then move up to the next HP level and start over. In a couple hours you should be able to dial in a set of 100, 125 and 150hp jets, or whatever you're looking for.

I get my jets at a local speed shop. You could end up buying a lot of jets to do this exercise, so I'd recommend borrowing jets from as many friends as possible, since you won't end up needing to own most of the ones you tune with...

You said:"The best way to do this is to tune with the fuel jets right?" Are you looking to try and flow your nitrous kit fuel jet or are you referencing how to tune your nitrous kit with a flow checker? It sounds to me your asking about jets for a flow checker. If this is the case you would use the same jets used in the kit. You just need the formula on how to figure what jet size to flow with. If this is the case let me know and I will post the formula to calculate flow jet size. Just need to know is the kit a plate or nozzle and if nozzle how many?

 

I just wanted to get the a/f ratio where I wanted it when on the spray

 

Nice thing about a separate fuel system for nitrous - you can tune with fuel pressure instead of using countless pills
