Nitrous Oxide Systems knows just how important it is to be able to monitor your engines nitrous system. A sudden loss in fuel pressure can spell disaster, possibly destroying your engine and ruining your day. That’s exactly why NOS came up with their analog-style 2-1/16" standalone gauges. Our NOS analog gauges offer you a simple, yet modern way to keep tabs on your vehicles fuel and nitrous pressures, without the need for a separate module or aftermarket ecu to obtain the data. Whether your set up has a carburetor, or your running fuel injection, NOS has a fuel pressure gauge  perfect for your set-up. We offer a low pressure gauge for use with carbureted fuel systems running pressures up to 15psi, as well as a version for you EFI users with fuel pressures as high as 120psi. 


Don’t take the chance and guess on the condition of your nitrous bottle ever again. Our Nitrous gauge helps you keep tabs on your bottle pressure and provides an accurate reading from 1 to 1500 psi, without ever leaving the driver’s seat. For the most accurate readings, the pressure sending unit should be installed as close as possible to the supply bottle. Once you’ve got your nitrous kit installed, how do you know if the jetting is correct? Sure you can go by what the jetting charts suggest, or you can make multiple passes and keep pulling plugs every-time, or just cross your fingers and send it!! I don’t know about you, but for me, nothing beats real life feed-back. That’s why we created our standalone Wideband O2 kit. It’s a feature packed analog-style gauge that’s designed for use with all EFI and carbureted systems. And it’s a perfect way to take the guess work out of determining your engines actual air/fuel ratios. Not only does it monitor AFRs, it also features an adjustable LED warning light that allows the user to set both a high and a low trigger points to warn you of potential problems. A peak recall button lets you a view your maximum gauge readings at a glance. The NOS O2 kit includes a Bosch wideband O2 sensor that’s fully compatible with Unleaded, Leaded, E85, Methanol, and Diesel fuels. Also included is a 5 ft.long 6-pin weather-tight sensor harness and a 4 foot power and lighting harness to give you plenty of flexibility when mounting.


We all know dash space can be at a premium. So our NOS 2 1/16” gauges utilize a slim mount design, that requires a minimal amount of depth behind your dash panel to flush mount them. But if you’d rather mount the gauge under your dash, on the roll bar, or in a custom location, Holley offers pedestal mount brackets designed for use with the NOS 2 1/16” gauges. Pedestal mounts part # 26-619 feature a durable billet aluminum base that comes predrilled for an easy install. They include black powder-coated metal straps and rubber inserts for superior vibration resistance. NOS analog gauges use an internal microprocessor, this ensures a smooth 270 degree sweep pattern and our high visibility red pointers are driven by high-torque internal stepper motors. We use stepper motors to ensure accurate pointer movement and eliminate that ominous needle bounce that you sometimes get with mechanical gauges. The dimmable LED backlighting, makes the gauges even easier to see, no matter what the light conditions might be. Our stand alone nitrous pressure, air/fuel ratio and fuel pressure gauges are available in 2 color combos, black background with white lettering or white face with black lettering. And if your looking to change up the look of your dash it couldn’t be easier! Our anodized bezels are CNC machined from billet aluminum and fully threaded so you can quickly swap them out and change up your look using any of the replacement bezels available on our website. We fully test each unit to insure you receive a top quality accurate gauge. And all gauges include a corresponding sending unit or sensor depending on the gauge type that you purchase.
