Wizards of NOS - Nitrous Gauge 40mm Bottle and Remote Mount

• During cold spells or in cold climates, low nitrous pressure will be detrimental to performance. However, this can be overcome by fitting our Black Knight bottle heater which can be found here

• Should you decide to fit a heater, adding a bottle pressure gauge is a worthwhile addition to ensure the pressure doesn’t get too high.

• Just like all WON products, our bottle pressure gauge is of the highest quality and identifiable by it’s polished stainless steel case and our WIZARD of NOS logo.

• Although it is possible to fit the gauge directly to the WON valve, the procedure must be carried out by WON or a capable engineer, as the gauge port must be finish drilled and tapped, to accept the direct fit of the gauge.

• The gauge has a 1/8 BSP male thread, so for anyone wanting to fit the gauge quickly and easily (without any additional machining), a suitable adapter kit to suit the type of pipe/fittings you're using for where you want the gauge to be mounted, will need to be selected from the drop down menu. You'll find details of the options listed below; 

When the gauge is to be fitted between the bottle and the solenoid (normally on the bottle outlet) a suitable adaptor is required. In the above drop down menu, we offer option 2 (to suit WON 5mm nylon pipe) & option 3 (to suit 4AN braided hose).

 If the gauge is to be fitted remotely from the bottle (in a dash for example), we offer a suitable plumbing kit. We can supply these kits for use with either 5mm or 4AN supply pipe (listed respectively in the above drop down menu as option 4 & 5) and they include;

• 1 x 5mm to 5mm M/M connector (1/8 BSPT [M] to 5mm [F] adaptor when used with 4AN hose)

• 1 x T-piece (5mm or 4AN)

• 1 x 1/8 BSP (F) to 5mm (F) elbow adaptor for gauge

• 2 meters of 5mm high pressure pipe

• 2 x 5mm nuts/olives

N.B. The 'Remote location plumbing kit for 4AN braided' is actually supplied with 5mm nylon pipe to connect the bottle outlet to the gauge

Nylon Lines vs. Braided SS

IMPORTANT: The purpose of the following information is not to deny the ‘general’ qualities of stainless steel braided hose, it is only for the two following reasons:

1. To make the facts known as to why ‘our’ nylon pipe, is better suited to nitrous use for optimum results.
2. To dispel all the ill informed claims that ‘our’ nylon pipe is inferior to braided pipe. 

Before considering the following information, please consider the following facts. It is now almost universally accepted, that WON Pulsoids are vastly superior to ‘generic’ solenoids, as supplied in all other brands of nitrous kits. Does it therefore not make sense that we’d also supply the ‘best’ pipe for the job?  We'd also like to point out that when higher flow rates are required than the nylon is capable of flowing, we do supply braided hose between the bottle and nitrous solenoid.

• Misconception 1) Braided hose can handle more pressure. Truth; At ambient temperatures under 30 degrees that is not the case, as Wizards of NOS nylon pipe is capable of handling approx. 6,000 psi. However, even if it were true, what is the point of using pipe that is capable of handling more pressure than it will ever be subjected to? Furthermore, as it is dangerous to your engine to supply it with nitrous above 1,000 psi, it would be safer to use a pipe that would burst just above that pressure, to act as a safety switch/fuse and warning indicator.
• Misconception 2) The stainless steel outer braid shields the hose contents from heat.  Truth; The outer braid actually ‘conducts’ and ‘holds’ heat in closer proximity to the contents, than would be the case without it. This misconception has lead to some extreme instances, where people have secured the hose to the exhaust system, which has vaporised the liquid nitrous into gas and resulted in no extra performance. In contrast, Wizards of NOS pipe is made of nylon that is a very good ‘insulator’ and therefore ‘does’ shield the contents from heat.
• Misconception 3) Braided hose is indestructible.Truth; The interwoven strands are the only protection the inner hose has but if only ‘one’ strand gets damaged, the whole hose integrity is lost, because the inner plastic (PTFE) hose has no strength. Contrary to people’s expectations, it is very easy to snag more than one strand on a sharp edge, especially when routing the hose through the car.
• Misconception 4) All braided hose is high flow. Truth; Braided hose end fittings go ‘inside’ the hose and the bore of these fittings is much smaller than the bore of the hose itself and as a consequence the flow rate is much lower than the pipe bore along would support.

Detrimental consequences of this hose assembly design/technique are as follows;

1. The steps created by the fittings cause the nitrous liquid to phase change to gas, as it passes through the fittings. This does not apply to Wizards of NOS nylon pipe, as the fittings are external to the pipe.
2. The much larger bore of the braided hose acts as a large reservoir for the initial gaseous (not liquid) nitrous build-up prior to activation,  that will result in a ‘dramatic’ loss in performance unless it’s purged to atmosphere and wasted before every operation. This is not a problem with Wizards of NOS nylon pipe, as the ‘very’ small bore means there is minimal build-up so purging (waste) is not needed to achieve optimum results.
3. In competitor's kits the braided hose is supplied in a fixed length, which means the surplus hose has to be coiled up, which results in an even bigger unnecessary waste of nitrous. WON nylon pipe can be cut to the ‘minimum’ length required to avoid this waste.

For even more reasons to use WON nylon pipe rather than braided hose, please read the following forum thread;
