Do you need a tune for 50 shot of nitrous?

Do you need a tune for 50 shot of nitrous?

You need a revision for any nitrous shot, particulary on a tuned car, which will have an aggressive timing curve. 50 you won’t even feel.

Do you need a tune with a wet shot of nitrous?

You don’t “need” a tune for a small wet shot. They are jetted to run fairly rich (usually). It’s definately a great idea though. At least dyno it with wideband to see how its running.

Do you need tuning for nitrous?

You don’t “have” to have a nitrous tune. I do have a “mail-order” nitrous tune from Brenspeed.com.

Is dry or wet nitrous better?

Dry nitrous kits are a great first step and require less work for installation and a small bump in power output. A wet nitrous kit will deliver a fuel/nitrous oxide mixture into your intake tract. However, with a wet nitrous kit, there is more risk of backfire.

How long does nitrous last in a car?

A rolling start from 60 mph and run to 180 is very short. After the initial novelty wearing off (it is a blast) and you become judicious with the use, a bottle (20 lbs) can last about 5 to 7 days. A bottle refill is $50.

How much timing Do I pull for nitrous?

Ignition Timing Most nitrous companies suggest retarding timing by 1.52. 5 degrees per 50 hp of nitrous use. For example, a 200hp nitrous tune would require the timing to be retarded from 6 to 10 degrees.

What’s the difference between wet nitrous and dry?

A “Wet System” adds additional fuel with a separate pump through the same plate or nozzle, supplying the nitrous oxide. A “Dry” nitrous system relies on the existing fuel system, whether it’s fuel injected or carbureted, to supply the additional fuel needed when the nitrous system is activated.

What should ignition timing be for nitrous oxide?

Ignition timing should as a baseline be retarded to 1/5 to 2 degrees for every 50 h.p. worth of nitrous hp used. Ignition timing should be retarded from the best timing on motor only. (The point at which best MPH or Torque was achieved.)

How long can you run a bottle of nitrous oxide?

Maxwell: A good rule of thumb is 0.8lbs of nitrous oxide is used on a 100hp shot for 10 seconds. In other words, you could run a 100hp shot for a total of 125 seconds to run the bottle out of nitrous.

When to change the nitrous in a car?

The performance starts to drop off as the bottle gets closer to empty. Most serious racers keep a few full spare bottles on hand and swap them out when the one in the car is down to about 4lbs, or they notice that the power has started to fall off. “You won’t have to worry about nitrous freezing, but a cold bottle hurts performance.

What’s the best temperature for a Nitrous bottle?

Nitrous works best between 900 and 1000psi, at around 85-90 degrees Fahrenheit, which is why a bottle heater is one of the best accessories you can buy. It keeps the bottle up at the proper temperature for the best performance. However, as bottle temperature rises, the pressure inside increases.

How many quarter mile passes can a nitrous do?

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.

How is nitrous oxide used in engine tuning?

TUNING TECHNICAL INFORMATION Nitrous System Theory, Selection, and Tuning As modern engines become more difficult to modify, the use of nitrous oxide to obtain phenomenal performance gains is on the rise and for good reason. We firmly believe that our nitrous systems and related products are the highest quality, performance, and value available

How does a nitrous oxide system reduce turbo lag?

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.

Why are nitrous oxide injection systems so efficient?

Nitrous oxide injection systems are probably the most efficient way to increase the flow of oxygen and fuel. That’s the basic reason why nitrous systems produce such large horsepower increases. Another basic power factor is vaporization of the fuel. Gasoline, as with other racing fuels, will not burn in a liquid state.
