Here are some Q's and A's for you. Enjoy!
Q: Will Nitrous affect engine reliability?
A: The key is choosing the correct H.P. for a given application. A kit that uses the correct factory calibration does not usually cause increased wear. As the energy released in the cylinder increases so do the loads on the various components that must handle them. If the load increases exceed the ability of the components to handle them, added wear takes place. Nitrous kits are designed for use on demand and only at wide open throttle. Nitrous can be extremely advantageous in that it is only used when you want it, not all the time. Most Nitrous kits are designed for maximum power with reliability for a given application.
Q: Can I simply bolt a nitrous kit onto my stock engine?
A: Yes. Most manufactures systems for virtually any stock engine application. The key is to choose the correct kit for a given application; i.e., 4 cyl. engines normally allow an extra 40-60 HP, 6 cyl. engines usually work great between 75-100 extra HP, small block V8's (302/350/400cid) can typically accept up to 140 extra HP, and big block V8's (427-454) might accept from 125-200 extra HP. These suggested ranges provide maximum reliability from most stock engines using cast pistons and cast crank with few or no engine modifications.
Q: What are some of the general rules for even higher HP gains?
A: Generally, forged aluminum pistons are one of best modifications you can make. Retard ignition timing by 4-8 degrees (1 to 1-1/2 degrees timing retard per 50 HP gain). In many cases a higher flowing fuel pump may be necessary. Higher octane (100+) racing type fuel may be required as well as spark plugs 1 to 2 heat ranges colder than normal with gaps closed to .025"-.030". For gains over 250 HP, other important modifications could be necessary in addition to those mentioned above. These special modifications may include a forged crankshaft, a high quality race type connecting rods, a high output fuel pump dedicated to feeding the additional fuel demands of the nitrous system, and a racing fuel with high specific gravity and an octane rating of 110 or more.
Q: How does nitrous work?
A: Nitrous oxide is made up of 2 parts nitrogen and one part oxygen (36% oxygen by weight). During the combustion process in an engine, at about 572 degrees F, nitrous breaks down and releases oxygen. This extra oxygen creates additional power by allowing more fuel to be burned. Nitrogen acts to buffer, or dampen the increased cylinder pressures helping to control the combustion process. Nitrous also has a tremendous "intercooling" effect by reducing intake charge temperatures by 60 to 75 degrees F.
Q: How much performance improvement can I expect with a nitrous system?
A: For many applications an improvement from .5 to 3 full seconds and 5 to 15 MPH in the quarter mile can be expected. Factors such as engine size, tires, jetting, gearing, etc. will affect the final results.
Q: How long will the bottle last?
A: This largely depends on the type of nitrous kit and jetting used. For example, a 125 HP Power Shot kit with a standard 10 lb. capacity bottle will usually offer up to 7 to 10 full quarter-mile passes. For power levels of 250 HP, 3 to 5 full quarter-mile passes may be expected. If nitrous is only used in 2nd and 3rd gears, the number of runs will be more.
Q: How long can I hold the nitrous button down?
A: It is possible to hold the button down until the bottle is empty. However 15 continuous seconds at a time, or less, is recommended.
Q: When is the best time to use nitrous?
A: At wide open throttle only (unless a progressive controller is used). Due to the tremendous amount of increased torque, you will generally find best results, traction permitting, at early activation. Nitrous can be safely applied above 3,000 RPM under full throttle conditions.
Q: Is nitrous oxide flammable?
A: No. Nitrous Oxide by itself is non-flammable. However, the oxygen present in nitrous oxide causes combustion of fuel to take place more rapidly.
Q: Will nitrous oxide cause detonation?
A: Not directly. Detonation is the result of too little fuel present during combustion (lean) or too low of an octane of fuel. Too much ignition advance also causes detonation. In general, most kits engineered for stock type engines will work well with premium type fuels and minimal decreases of ignition timing. In racing application where higher compression ratios are used, resulting in higher cylinder pressures, a higher fuel octane must be used as well as more ignition retard.
Q: Is there any performance increase in using medical grade nitrous oxide?
A: None! Most sell only the automotive grade, called Ny-trous Plus. Ny-trous Plus contains a minimal amount of sulfur dioxide (100 ppm) as a deterrent to substance abuse. The additive does not affect performance.
Q: Is it a good idea to use an aftermarket computer program in conjunction with an ntrous System?
A: Only if the program has been designed specifically for use with nitrous oxide. Most aftermarket programs use more aggressive timing advance curves to create more power. This can lead to possible detonation. You may wish to check with the manufacturer of the program before using it.
Q: Does nitrous oxide raise cylinder pressure and temperatures?
A: Yes. Due to the ability to burn more fuel, this is exactly why nitrous makes so much power.
Q: Are there any benefits to chilling the nitrous bottle?
A: No. Chilling the bottle lowers the pressure dramatically and will also lower the flow rate of the nitrous causing a fuel rich condition and reducing power. On cold evenings you might run on the rich side. For optimal running conditions, keep bottle pressure at approximately 900-1050 psi.
Q: Are there benefits to using nitrous with turbo or super-charger applications?
A: Absolutely! In turbo applications, turbo lag is completely eliminated with the addition of a nitrous system. In addition, both turbo and superchargers compress the incoming air, thus heating it. With the injection of nitrous, a tremendous intercooling effect reduces intake charge temperatures by 75 degrees or more. Boost is usually increased as well, adding to even more power.
Q: What affect does nitrous have on an engine with considerable miles on it?
A: This depends largely on the actual condition of the engine components. Any performance modification to an engine that is worn out or poorly tuned will have detrimental effects. However, an engine in good condition, with good ring and head gasket sealing, should be able to use nitrous without any abnormal wear.
Q: Will the use of nitrous oxide affect the catalytic converter?
A: No. The increase in oxygen present in the exhaust may actually increase the efficiency of the converter. Since the use of nitrous is normally limited to 10-20 seconds of continuous use, there usually are no appreciable effects. Temperatures are typically well within acceptable standards.
Q: Can high compression engines utilize nitrous oxide?
A: Absolutely. High or low compression ratios can work quite suitably with nitrous oxide provided the proper balance of nitrous and fuel enrichment is maintained. Nitrous kits are used in applications from relatively low compression stock type motors to Pro-Modifieds, which often exceed 15 to 1. Generally, the higher the compression ratio, the more ignition retard, as well as higher octane fuel, is required.
Q: Can service station fuel be used for street/strip nitrous oxide applications?
A: Yes. Use of a premium type leaded or unleaded fuel of 92, or greater, octane is recommended for most applications. Many nitrous systems are designed for use with service station pump gas. However, when higher compression or higher horsepower levels are used, a racing fuel of 100 octane, or more, must be used.
Q: What type of cam is best suited for use with nitrous oxide?
A: Generally, cams that have less exhaust overlap and more exhaust duration. However, it is best to choose a cam tailored to normal use (when nitrous is not activated) since 99% of most vehicle operations is not at full throttle. There are special cam grinds available for nitrous competition which have more aggressive exhaust profile ramping, etc. Since cam selection depends largely on vehicle weight, gearing, etc., it is best to stick to cam manufacturers' recommendations for your particular goal.
Q: Should I modify my fuel system to use nitrous oxide?
A: Most stock fuel pumps will work adequately for smaller nitrous applications. It is important to check to see if your pump can flow enough fuel to your existing fuel system (whether carburetor or fuel injected), as well as being able to supply the additional fuel required by the nitrous kit under full throttle conditions. It may be a good idea to dedicate a separate fuel pump to the nitrous kit.

Q: Which is the best position to mount a nitrous bottle?
A: Nitrous bottles come with siphon tubes and, in order to maintain proper nitrous pickup, it is important to mount the bottle correctly. You should mount the bottle at a 15 degree angle with the valve end higher than the bottom of the bottle. The valve end of the bottle should point to the front of the vehicle and the valve knob and label should face straight up.
Q: How important is it to use nitrous and fuel filters in a kit?
A: Some of the most important components of any nitrous system are nitrous and fuel filters. To keep contaminants from attacking the solenoid or plugging up a jet, nitrous filters feature a special stainless steel mesh element from the aerospace industry.
Q: What are the advantages of using nitrous compared to other performance options?
A: The cost of many other performance options can put you in the poorhouse. Dollar for dollar, you can't buy more performance with less money than nitrous. With a nitrous system, performance and reliability can be had for a much more reasonable price while still retaining the advantage of a stock engine during normal driving. And, Nitrous offers tremendous gains in torque without having to rev the engine to excessive rpm's.
Q: How do I know how much nitrous is left in the bottle?
A: The most reliable method was is to weigh the bottle to determine how many pounds remain. When a bottle is near empty (about 20% or less nitrous remaining) a surging effect is normally felt.
Q: What is the function of the blow-off safety valve on the bottle?
A: It is very important not to overfill a bottle; i.e., a 10 lb. capacity bottle should not be filled with more than 10 lbs. of nitrous oxide by weight. Over-filling and/or too much heat can cause excessive bottle pressures forcing the safety seal to blow and releasing all the contents out of the bottle.
Q: Will I have to change my ignition system?
A: Most late model ignition systems are well suited for nitrous applications. NGK TR-6 plugs are recommended.
CAN YOU RUN NITROUS WITH A 6 SPEED CAR?
Yes. Just make sure that you have the correct safety equipment before you do so.
WOT Switch
Window Switch
FPSS
How do I hook up my MSD window switch to my 5177 kit? Thanks
to Dheck for this illustration.
MSD Window Switch Diagram on 5177 Kit (http://68.78.14.87/NOS%20INSTALL%20GUIDE.jpg)
WOT - Wide Open Throttle Switch. It is placed inline with your arming switch, FPSS, and any other safety devices to activate your nitrous. This can be placed either near the throttle body or a momentary push button underneath the gas pedal for a stealth install.
Window Switch - Another wonderful (shouldn't be without) safety device. A must for a M6. It also installs inline with your FPSS, WOT, arming swithch, etc. The window switch does excatly what it says, it is a window for your nitrous to activate. Example. If you have you window switch setup for 3k and 6k, then the nitrous will only activate between those RPM's. It will come on at 3k and automatically shut off at 6k. (Providing it is wired correctly.) Some use pills while others just use dials or dip switches to set the corresponding RPM.

well if your good like that then im extremely happy for u and good luck, we never said anything about u , u jumped in it when it was started with someone else. and i also never said your abilities werent good or that your car was crap u assumed that, i was making a general statement about the subject
i see your have 2 cars right?and your 14 right? and a 98 isnt cheap so im guessing your dad bought it for you correct? and the engine swap and all that, did your dad help you with everyhting else also or did u actually do it all on your own. im just curious because if all you little kids are just workin with daddy saying your doin your work on your own then stop bitching, if u do it yourself then ok i guess u have a little room to complain, but give it up

The 98 my dad did buy for me but we practically stole it off the dealer for a measly 5grand. The work on my cars is done by me and only me my dad has not even sat in my car since he bought it for me in 03. If he does help me its because its soemthing that one person can not do on there own I can also tell you that i put the motor and tranny in the car by myselft with no one around and i have also dropped the tranny by myself twice. I would also like to imply that I do all the work on my parents cars also now, oil changes, brakes all that ****, i wax the vette for my dad and im also the one who installs everthing on it for him like the slp loudmouth.
