Frequently asked questions

How much horsepower does this nitrous system make?
It is jetted for 35–200 HP (jetting for 35, 50, 75, 100, 150, 200 HP). Start at the low end, check your plugs and timing, and step up from there.

What else should I plan for when adding nitrous?
Most racers pair a nitrous kit with a bottle heater, a purge kit, a fuel pressure safety switch and colder spark plugs, and pull timing to suit the shot size. Call us at 713-938-4033 and we will help you spec the right combination.
