Q. How much nitrous can I run on my motor?

A. That question cannot be answered without a lot more information, however almost any V8 engine can run up to 150HP boost without any concerns.

Q. I have read on many Internet forums that running nitrous safely on a carbureted Small Block Ford is impossible.

A. It is true that the inherent design of the carbureted SBF is very difficult to evenly distribute nitrous however it is not impossible to do it successfully. Nitrous Express’s Gemini Twin Direct Port nitrous plates, PN 60040, are the only ones in the industry that can get nitrous and fuel evenly in every port of a SBF. Adjustability from 50 to 500 horsepower provides something for almost everybody.

Q. What about the Big Block Fords on nitrous?

A. Big Block Fords enjoy the same benefits from the Gemini Twin Direct port design. Each port is individually targeted with a direct spray of nitrous and fuel to assure each cylinder gets its fair share of the good stuff.

Q. I am installing a nitrous system on my 4.6 2004 Mustang. Ford no longer provides a pressure check port on the fuel rail, how do I get the fuel for the nitrous system?

A. NX PN 16183 fuel rail adaptor raises the fuel pressure sensor and provides two 1/8 NPT ports for nitrous or a fuel pressure gauge. NX PN 16184 is for the Cobra 4 valve motors and the Ford pick-ups.

Q. Does NX make a specific nitrous system for my new Mustang 3 valve motor?

A. Yes! Check out the ultra cool 3V plate system PN 20947. This one of a kind design uses an exclusive Phase 3 spraybarless design and integrated solenoids for a uniquely safe and compact nitrous system.

Q. I have an older two valve 4.6 is there anything special for it?

A. Yes! PN 20946 is a 4.6 exclusive system. The Phase 3 spraybarless design plate sandwiches between the plastic intake manifold and the 90-degree aluminum throttle body adaptor. Standard horsepower settings are 50-100-150 with optional setting of 200-250-300 for modified engines. One of our best selling systems.

Q. I have a 5.0 EFI engine with an aftermarket intake manifold; do you make a plate style system for it?

A. NX produces a plate style system for every 5.0 intake manifold manufactured today. For example the PN 20100 is a system for the stock 5.0 manifold. These systems feature the Phase 3 spraybarless design and every plate is dual stage capable. Standard horsepower settings are 50-100-150-200-250-300 and with a simple dual stage up-grade these horsepower numbers double!

Q. What is a progressive controller?

A. The NX Maximizer PN 15959 is an electronic nitrous controller that allows you to apply the nitrous power is a controlled or ramped manner. For instance you can jet your nitrous system for 300HP but launch the car with only 50HP and have the controller ramp up the power over a pre-set amount of time to 300HP. This helps your car handle the tremendous torque produced by the NX “Next Generation” nitrous technology.

Q. I checked out the Maximizer but its out of my budget range, don’t you have anything for the little guys?

A. The Mini Controller PN FJOKWS0022 is just what you are looking for. It has many of the great features of the Maximizer but at a fraction of the cost!

Q. I read on the Internet that progressive controllers eat solenoids, is this true?

A. NX “Lightning” solenoids, PN 15200L for example, were specifically designed to be used with a progressive controller and have a limited life-time warranty. Do not try to run the other guys “off shore” solenoids, they can’t take it!

Q. Does NX offer custom nitrous systems?

A. Yes, NX has a complete shop facility that is geared to make the most difficult nitrous applications easy, at least for the customer! Everything from classic cars, to hidden systems, to nitrous for the most obscure applications there’s no challenge too big for NX.

Q. What is a purge valve and do I need one?

A. The purge valve is an auxiliary nitrous solenoid that is activated manually by the driver prior to a nitrous assisted pass. This solenoid vents the gaseous nitrous from the supply line that connects the nitrous bottle to the nitrous solenoid. This allows a pure liquid nitrous charge to enter the engine for an instant surge of power. A purge valve is worth about a tenth of a second on a quarter mile pass. Yes, everyone needs a purge valve.

Q. I have a small roots type blower on my street rod, the blower is really cool but just does not produce enough power to satisfy my need for speed. Can you help?

A. The small street blowers can benefit greatly from a small plate style nitrous system. A PN 30040 conventional plate system can turn your 4-71 street blower into a raging 14-71 beast! A 100HP jet setting can produce a true 150HP rear wheel blast. How you ask; the nitrous discharges at 127 degrees below zero, this provides the ultimate intercooler while still producing the advertised 100HP. The 50 extra ponies are just a bonus.

Q. I have a budget 1968 Mustang with a crate engine. The car is great to drive and gets awesome fuel economy but the power is just not there, HELP!

A. You are a great candidate for our PN ML1000 MainLine economy nitrous system. Adjustable 50-100-150HP this system is designed for the hot rodder on a budget. It still uses the same rugged technology as our top of the line systems but all of the “Fluff” has been taken out to lower the price to rock bottom.

Q. I have an 4.6 engine with a centrifugal supercharger, can I use nitrous?

A. NX specializes in blower and turbo nitrous applications. Any NX 4.6 nitrous system combined with a NXd5000 controller is the ultimate set-up. The PN NXd5000 is a boost referenced progressive controller that senses boost and automatically ramps the nitrous charge out as the boost comes up. This controller can handle two stages of nitrous and can ramp in either a boost or time reference. This allows for a straight torque “curve” with no soft spots. The ultimate in nitrous/boost control!

Q. I have an stroked Windsor engine with a centrifugal blow through supercharger, can I use nitrous?

A. NX specializes in blower and turbo nitrous applications. Combine the PN 60040 Gemini Twin direct port system with the NXd5000 controller is the ultimate set-up. The PN NXd5000 is a boost referenced progressive controller that senses boost and automatically ramps the nitrous charge out as the boost comes up. This controller can handle two stages of nitrous and can ramp in either a boost or time reference. This allows for a straight torque “curve” with no soft spots. The ultimate in nitrous/boost control!

Q. What is the best gasoline to use with nitrous?

A. As a general rule the higher the octane the better, however steer clear of oxygenated fuels. They have high octane ratings but already have an added oxygen component. This can result in a very lean condition resulting in detonation and engine damage. There are several good companies that offer a nitrous specific fuels. Use the highest octane you can get and you will never be sorry.

Q. My race car runs on methanol, can I run nitrous with alcohol?

A. Yes, Nitrous Express specializes in N2O/methanol nitrous applications. Every nitrous system NX sells is available in alcohol enrichment. A strong ignition system is required, but the results are worth the effort. Hugh amounts of torque and detonation resistance are the benefits of using methanol.

Q. Can I rebuild my own solenoids?

A. Yes, all NX solenoids are field serviceable, however all NX solenoids have a limited-Lifetime warranty so no rebuilding should be necessary.

Q. How important is bottle pressure?

A. Bottle pressure is critical to a reliable, repeatable nitrous system. The minimum required to enjoy a trouble free nitrous system is a nitrous pressure gauge PN 15509, and a bottle heater PN 15940.
