What compression is needed for nitrous?
NOS 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.
Do you need to lower compression for nitrous?
1) A higher ratio will make more power NA but will have a lower limit of how much nitrous it can handle. 2) A lower ratio will make less power NA but will be able to take more nitrous before hitting any problems. The more nitrous you want to add to an engine, the lower the compression ratio would be most suitable.
Does Nos increase compression?
Q: Does nitrous oxide raise cylinder pressures and temperatures? A: Yes. Due to the ability to burn more fuel, this is exactly why nitrous makes so much power.
How much compression is too much for nitrous?
Anything above 15.00-1 is absolutely too much in a serious nitrous engine. Anything above 13.50 -1 should be ok.
What type of piston is best for nitrous?
We suggest a hardened nitrous series ring, carbon steel nitride ring, or a stainless steel ring for best longevity.” For durability, the design of the pin bores and supporting piston structure is critical.
Can you put nos in an automatic?
Yes, Nitrous Oxide Systems can be used with automatic transmissions and in the majority of cases automatic transmission can handle larger power increases than a standard factory manual clutch and gearbox.
Can a high compression ratio work with nitrous oxide?
A: Absolutely. High or low compression ratios can work quite suitably with nitrous oxide providing the proper balance of nitrous and fuel enrichment is maintained. NS kits are used in applications from relatively low compression stock type motors to Pro-Modified, which often exceed 15 to 1.
What should the pressure be on a 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. For optimum running conditions, keep bottle pressure at approximately 900-950 psi. NS has a nitrous pressure gauge that allows you to monitor this.
Why is my compression ratio too high for Nos?
5) The amount of nitrous you want to add (rather than just aiming for the maximum), also affects what compression ratio would be most suitable. The more nitrous you want to add to an engine, the lower the compression ratio would be most suitable.
What happens to the engine when you use nitrous oxide?
A: The key to engine reliability when using nitrous oxide is to choose the proper horsepower increase for a given application. Kits using the correct factory calibrations do not usually increase wear. Increased cylinder pressures also increase loads on the supporting components.
