1. Are CFS products compatible with my current Nitrous Oxide system?
A: Absolutely! Not only are they compatible but they enable your current system to make more horse power. In fact, just upgrading to one of our plate systems increases horsepower output from 1.5% - 2.0% without even changing jets.

2. Nitrous Oxide works in what way?
A: Nitrous oxide is made up of 2 molecules of nitrogen and one molecule of oxygen (36% oxygen by weight). During the combustion process, at about 570 degrees F, nitrous breaks down and releases oxygen. This extra oxygen creates additional power by enabling more fuel to be burned. Nitrogen acts to buffer the increased cylinder pressures helping to control the combustion process. Nitrous also has a tremendous "cooling" effect by reducing air intake charge temperatures by 55 to 85 degrees F.

3. Is engine reliability affected by Nitrous?
A: The solution is choosing the correct horse power for a given application. A kit that uses the correct power rating does not usually cause increased wear. As the power increases, so do the loads on the various parts that must handle them. If the load increases exceed the ability of the parts to handle them, added wear and tear takes place. CFS kits are designed for use only at wide open throttle. Nitrous can be extremely helpful. Use it only when you need it, not all the time. All CFS kits are designed for maximum power with reliability.

4. A CFS Nitrous System will give me how much performance improvement?
A: An improvement for many applications can be anywhere from 1 to 3 full seconds and 10 to 15 MPH in the quarter mile. Factors such as engine size, traction, weight distribution, gearing, etc. will affect the final results.

|
5. How can I achieve even higher horse power gains and what are some general rules to follow?
A: Generally, retarding ignition timing by 4-8 degrees (1 to 1-1/2 degrees timing retard per 50 HP gain). Forged pistons to increase reliability. In many cases a high performance fuel pump may be necessary. Higher octane (100+) racing 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 275 HP, other significant modifications could be necessary. These modifications allow for even higher HP and include a forged crankshaft, forged connecting rods, a dedicated high output fuel pump used to supply the
additional fuel demands of the nitrous system, and a quality racing fuel with high specific gravity and an octane rating of 110 or more.

|
6. Can I use Nitrous Oxide on a stock engine?
A: Yes. The most important aspect is not to overindulge. Choosing the correct kit for any given application is essential; a good rule of thumb to follow is never exceed 50% power increase to your current engine output.

|
7. What kind of R and D goes into CFS products?
A: Every CFS product goes through a strict set of guidelines to ensure that the consumer is getting the highest quality product on the market today. Our research and development laboratory include the most sophisticated computerized equipment. CFS is actively involved in racing and was established to expose and provide knowledge that until now has only been shared by the top racers.

| |
|
8. Is nitrous oxide flammable?
A: No. Nitrous Oxide by itself is non-flammable.
|
| |
|
9. Does nitrous oxide cause detonation?
A: Not directly. Detonation can be the result of many things, such as a lean condition caused by not adding enough fuel, too low of an octane of fuel, and tmustoo much ignition advance. Most of our kits work well with stock type engines running on premium type fuels and minimal decreases of ignition timing. In racing application where higher compression ratios are used, a higher fuel octane be used as well as more ignition retard.
|
| |
|
10. Will my ignition system have to be changed?
A: Most late model ignition systems are suited for nitrous applications. In some higher HP cases, it is an advantage to have a high quality ignition system.
|
| |
|
11. As compared to other performance options, what are the advantages of using Nitrous?
A: Dollar for dollar, you can't buy more performance with less money than with nitrous. With a nitrous system, performance and reliability can be achieved while still retaining the advantage of a stock engine during normal driving.
|
| |
|
12. Will I need to modify my fuel system if I use Nitrous?
A: Most stock fuel pumps will work for smaller nitrous applications. It is important to flow check to see if your pump can supply enough fuel to your existing fuel system, 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.
|
| |
|
13. Can you use CFS kits on later model cars?
A: Yes.
|
| |
|
14. Can 93 octane fuel be used for street type nitrous oxide applications?
A: Yes. Many CFS systems are designed for use with pump gas. However, when higher compression or higher horsepower levels are used, a racing fuel of 100 octane, or more, must be used.
|
| |
|
15. Can you apply Nitrous Oxide to high compression engines?
A: Absolutely. High compression ratios work well with nitrous oxide provided the proper balance of nitrous and fuel enrichment is maintained. Generally, the higher the compression ratio, the more ignition retard, as well as higher octane fuel, is required.
|
| |
|
16. Will my catalytic converter be effected by Nitrous Oxide?
A: No. Since the use of nitrous is normally limited to 10-20 seconds of continuous use, there usually are no damaging effects. Temperatures are typically well within acceptable standards.
|
| |
|
17. What are the benefits of using nitrous with turbo or super-charger applications?
A: In turbo applications, turbo lag is completely eliminated with the addition of a nitrous system. 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 even more power.
|
| |
|
18. Which type of manifold is better for Nitrous Oxide applications, single or dual plane manifold?
A: The distribution is better with a single plane at high RPM. If your goal is to increase power by more than 150 HP, the single plane manifold is better.
|
| |
|
19. How long does it generally take to install an CFS kit?
A: The majority of CFS kits can be installed using common hand tools in approximately 4 to 6 hours.
|
| |
|
20. Should I use an aftermarket computer chip in conjunction with an CFS System?
A: Only if the chip has been designed specifically for use with nitrous oxide.
|
| |
|
21. When is the best time to use nitrous?
A: At wide open throttle only. Due to the tremendous amount of increased torque, you will generally find best results, traction permitting, at early activation.
|
| |
|
22. What affect does nitrous have on a high mileage motor?
A: This depends primarily on the actual condition of the engine. Any performance modification to an engine that is worn out or poorly tuned will have harmful effects. However, an engine in good condition, with good ring and head gasket sealing, should be able to use nitrous without any abnormal wear.
|
| |
|
23. What is the best cam shaft profile to be used with nitrous oxide?
A: Cams that have less exhaust overlap and more exhaust duration. If your vehicle is used for daily driving, your stock cam is fine. There are special cam grinds available for nitrous competition which have more aggressive exhaust profile ramping, etc.
