Nitrous oxide and fuel jets are both power-matched to complement a particular N₂O kit or application. For example, with Edelbrock Corporation’s 50- to 100-hp Universal Big-Block Chevrolet Square Flange Kit (PN 70001), the N₂O and fuel jets (three per grouping) are perfectly matched to their counterparts, such as: Nitrous/Fuel 38/38 = 50, 46/46 = 75, 57/57 = 100 hp.

However, that may not always be the case. For example, with Nitrous Supply’s Power Star Holley carburetor nitrous kit for the carbureted 350-ci small-block Chevrolet (PN 8001), jetting favors the nitrous side of the equation: Nitrous/Fuel 42/47 = 75, 47/53 = 100, 55/61 = 125, 63/71 = 150. Always pay close attention to the manufacturer’s recommended jet specification sheet.

As a rule, nitrous jets are all CNC machined out of brass or stainless steel. Why both? Originally, it was to visually determine the difference between fuel (brass) and N₂O (stainless). However, in recent years some N₂O kit manufacturers have exclusively switched to precision-machined stainless steel jets to avoid corrosion issues. Sized or upgraded nitrous and fuel jets are available in master jet packs through participating N₂O kit manufacturers and/or retailers.
