Making Use Of Laughing Gas to Boost Your Supercharger Performance
There comes a point in your power accumulation where you may consider adding laughing gas
injection to your supercharged cars and truck. This point usually accompanies reaching a level of efficiency that suggests increased financial investment and decreasing returns from your supercharger. For example, my vehicle originates from the factory with a fifth generation Eaton MP45 supercharger. This supercharger is restricted to about 230hp worth of circulation score and so no matter what I finish with http://store.yellaterra.com.au/search.php?mode=advanced bolt-on upgrades on my engine, my peak horsepower will not surpass 230hp limit since that is the point at which the supercharger becomes the bottle neck in my system.
As we’ve spoken about in previous posts there is still the choice of porting the factory supercharger for a 10 to 15% gain in capability (which in this case would be another 23 to 35 horse power). There is also the option of retrofitting a larger supercharger such as the Eaton M62 to gain possible approximately over 300hp depending on the final choice of a supercharger.
This modification path (changing the factory or porting supercharger) can show to be intricate and costly, specifically if the supercharger is incorporated into the intake manifold (and perhaps an air to water intercooler) as the case is with many factory supercharged vehicles.
A possible viable solution for this circumstance is to use nitrous oxide injection to supplement the power delivery when racing, and being pleased with a trusted lower powered car when the nitrous is off and we’re not racing.
The reason why laughing gas (N2O) becomes a fantastic power adder is twofold:
1- Nitrous is cheap as far as horse power per dollar goes, and especially in the circumstances where we’re currently supercharged and so will only be using it on the rare occasions when we do hit the track.
2- Nitrous oxide is a fantastic ‘chiller’ as it comes out of the bottle at a temperature level of unfavorable 127 * F and can cooling the total supercharged air charge mix by over 100 * F as reported by lovers, this is an extra temperature decrease over the results of whatever intercooler you have actually fitted. This in-fact makes nitrous a great proposal for cars and trucks that have actually currently maxed out their superchargers, where the supercharger is performing at peak rpms and producing really high outlet temperatures. The nitrous oxide injection can effectively enhance the thermal effectiveness of the supercharger when it is most stressed and give us a great, cool, and dense mixture.
3- Nitrous oxide fuel shipment is fairly straight forward to setup and to tune, specifically on newer design cars with return-les fuel systems, or difficult to crack computers that make it hard to upgrade (and effectively tune) a much larger supercharger setup. Laughing gas fuel delivery can be set-up completely independently from the OEM ECU and fuel system and therefore makes nitrous a possible application for German vehicles with persistent computer systems.
4- This is a racer method ... most cars seem to perform much better during the cold weather since the air is cooler, horsepower is elevated, and the tracks although cold, can be gotten ready for traction and will heat up enough throughout the night to permit traction and to offer people the capability to exploit the cold thick air to publish their best times of the year. As the weather gets warmer, traction boosts due to the fact that the asphalt is warm and sticky, but horse power is lowered due to warmer, less thick air. Usually racers discover that their cars and trucks differ in their quarter mile performance by as much as a half a 2nd in between their summertime tune and their winter season tune, especially if you’re utilizing a supercharger or turbocharger that compresses (and further warms) the incoming air.
The solution to on-track consistency, racers have discovered, is to integrate the usage of nitrous oxide (which is summertime friendly) with forced induction (superchargers and turbochargers) which are winter friendly. While in the winter, the outdoors temperature levels drop substantially, the nitrous in the bottle contracts and the bottle pressure drops, subsequently, the nitrous flow rate drops and nitrous assisted cars show even worse efficiency in the winter season times.
The total opposite holds true for supercharged cars and trucks that produce fantastic horse power in the winter season from compressing cool thick air, and poor horsepower in the summertime heat. When you integrate these two power adders you get consistent and pretty flat horsepower production year round since the supercharger shines when the nitrous is weak, and the nitrous shines when the supercharger is weak, and hence together, they provide constant power deliver year round.
