There comes a point in your power buildup where you might take into consideration adding nitrous oxide injection to your supercharged car. This point commonly accompanies getting to a level of performance that indicates boosted investment and lessening returns from your supercharger. As an example, my automobile originates from the manufacturing facility with a fifth generation Eaton MP45 supercharger. This supercharger is limited to about 230hp worth of flow score and so regardless of what I perform with bolt-on upgrades on my engine, my peak horsepower will certainly not surpass 230hp restriction since that is the point at which the supercharger ends up being the container neck in my system.
As we have actually talked about in previous posts there is still the choice of porting the factory supercharger for a 10 to 15% gain in capacity (which in this instance would certainly be an additional 23 to 35 horsepower). There is likewise the choice of retrofitting a larger supercharger such as the Eaton M62 to gain prospective up to over 300hp relying on the final option of a supercharger.
This adjustment course (porting or replacing the factory supercharger) can confirm to be intricate as well as pricey, especially if the supercharger is integrated right into the consumption manifold (and potentially an air to water intercooler) as the instance is with several factory supercharged automobiles.
A feasible sensible remedy for this circumstance is to utilize laughing gas shot to supplement the power delivery when racing, and also being satisfied with a dependable lower powered auto when the nitrous is off as well as we're not competing.
The reason that nitrous oxide (N2O) ends up being a great power adder is twofold:
1- Nitrous is economical regarding horse power per dollar goes, as well as especially in the situations where we're already supercharged and so will only be utilizing it on the rare events when we do strike the track.
2- Nitrous oxide is a great 'chiller' as it comes out of the bottle at a temperature level of unfavorable 127 * F and also is capable of cooling down the total supercharged air cost mixture by over 100 * F as reported by fanatics, this is an additional temperature decrease over the results of whatever intercooler you have fitted. This in-fact makes nitrous a fantastic recommendation for cars that have currently maxed out their superchargers, where the supercharger is going for peak rpms and creating extremely high electrical outlet temperatures. The nitrous oxide injection can properly enhance the thermal performance of the supercharger when it is most stressed as well as offer us a great, trendy, and also thick mix.
3- Laughing gas fuel shipment is fairly simple to setup and also to tune, particularly on more recent design cars with return-les gas systems, or difficult to split computer systems that make it difficult to upgrade (and effectively song) a much larger supercharger configuration. Laughing gas fuel delivery can be set-up totally separately from the OEM ECU and also gas system and therefore makes nitrous a feasible application for German cars and trucks with persistent computer systems.
4- This is a racer method ... most vehicles appear to perform better during the cold weather since the air is cooler, horsepower rises, and the tracks although chilly, can be planned for traction as well as will warm up sufficient during the night to allow for grip as well as to give people the capability to manipulate the chilly thick air to post their finest times of the year. As the weather Buy Cheap Whipple Superchargers Yella Terra obtains warmer, grip increases due to the fact that the asphalt is warm and also sticky, however horse power is decreased due to warmer, less dense air. Typically racers discover that their cars and trucks differ in their quarter mile performance by as long as a fifty percent a 2nd in between their summertime tune and also their winter months song, specifically if you're making use of a supercharger or turbocharger that compresses (and additional heats up) the incoming air.
The remedy to on-track consistency, racers have found, is to integrate the use of laughing gas (which is summer friendly) with forced induction (superchargers and also turbochargers) which are winter friendly. In the summer time, the outdoors temperature level is high, therefore the nitrous bottle pressure is maintained at a high level over 1100 psi. This enables a generous nitrous flow rate under the sustained stress (even without a container heating unit) which gives terrific summer season efficiency for nitrous assisted vehicles. While in the wintertime, the outdoors temperature levels go down substantially, the nitrous in the container agreements as well as the container pressure declines, consequently, the nitrous circulation price declines and also nitrous assisted cars show worse efficiency in the winter season times.
The full reverse holds true for supercharged vehicles that create excellent horsepower in the wintertime from pressing amazing dense air, and inadequate horsepower in the summertime warm. When you combine these 2 power adders you get pretty level as well as regular horsepower manufacturing all year because the supercharger shines when the nitrous is weak, and also the nitrous shines when the supercharger is weak, and hence together, they offer constant power supply all year.
Pre-cautions:
Currently we have to consider that nitrous oxide is an oxidizer and also hence not just does it boost the amount of air and gas combusting in the cylinder, however it additionally creates a quicker moving fire front because of the oxidizer residential properties of the laughing gas. This indicates that added timing slow down, fantastic octane gas, and also potentially colder spark plugs will certainly be required to run spray on a supercharged cars and truck. Moreover, due to its cooling impact, a 100hp shot on a supercharged Camaro can extremely easily take down OVER 120 rear wheel horsepower of additional power. This indicates that the 'out of the box' jetting of a nitrous package might not be adequate on a supercharged auto as well as you would certainly need to see to it to keep track of and also possibly enhance the fuel jetting to match the last horse power figure of your automobile). Finally, if you're running a 500hp supercharged automobile with an additional 120hp of nitrous oxide injection, after that you have to make certain that your gas distribution (fuel pump and also gas lines) are able to move the overall quantity of gas called for to provide 620hp.
Applications situations:
1- You have a car like mine, a 2005 C230 kompressor that includes a 230hp limited Eaton MP45. ECU on the car is a Siemens ECU that very few people recognize just how to tune, as well as the fuel system uses a return-less configuration with an in-tank gas stress regulator. With this sort of arrangement all forms of dry nitrous injection run out the question since we can neither compensate for gas through flashing the factory ECU, nor can we elevate gas stress during the nitrous shot because the fuel pressure regulator is in-accessible ... Suggested set:
A damp nitrous injection kit that infuses both gas and laughing gas from the injection nozzle.
Shot location:
After the supercharger, after the intercooler, and into the intake manifold of the vehicle.
Maximum suggested shot:
25% of the initial overall power figure which corresponds to around a 50 hp shot of nitrous on our instance.
Anticipated last horsepower:
60 to 65 wheel horsepower as well as feasible concerning 130 ft-lbs of additional torque!
2- You have an automobile that has an easily accessible gas stress regulator, or an ECU that can be re-flashed for laughing gas or a 'twin song' configuration. In this situation it is advised to utilize a dry nitrous kit for 2 reasons:
First: Dry kits are more secure on supercharged automobiles (as long as the gas shipment with the injectors or increased fuel pressure is adequate) since they hold a minimized possibility of intake backfires due to the fact that the consumption manifold is dry of gas.
Second: Dry nitrous shot has no fuel, therefore we don't need to worry about fuel befalling of suspension from the injected air. This suggests that we no longer have to spray the nitrous right before the consumption manifold as well as we currently have the choice to relocate the factor of injection much farther back. Spraying nitrous PRIOR TO the intercooler, right after the supercharger gives the nitrous stream even more time and also more contact with the pressed air coming out of the supercharger which results in more air conditioning and also additionally increased horse power.
Suggested package:
A dry nitrous injection kit that injects only laughing gas from the shot nozzle.
Injection area:
After the supercharger, prior to or Whipple Superchargers Perth after the intercooler and also not always ideal at the intake manifold of the auto.
Maximum advised shot:
25% of the initial total power figure which represents around a 50 hp shot of nitrous.
Expected last horsepower:
70-75 wheel horse power and possible concerning 130 ft-lbs of added torque!
3- You have an automobile that has an obtainable gas pressure regulator, or an ECU that can blinked for nitrous oxide or a 'twin tune' setup. You also wish to make as much horsepower as possible from your nitrous ...
In http://query.nytimes.com/search/sitesearch/?action=click&contentCollection®ion=TopBar&WT.nav=searchWidget&module=SearchSubmit&pgtype=Homepage#/powerful supercharger this instance it is suggested to utilize a completely dry nitrous kit injecting prior to the supercharger. As we discussed in our short articles on twin charging (integrating turbochargers with superchargers for added performance), when two 'chargers' are chained in series where one charger feeds the following, then the two stress proportions of the charger integrate since the 2nd charger compresses air that is already compressed by the very first. 2 turbochargers established for a 1.5 stress proportion (or 7 psi of boost), running in consecutive setting will result in a final pressure ratio of 2.25 bar (or 18psi of boost) which is much more than the 'anticipated' 14psi that is the sum of the two boost levels.
In a similar way, injecting nitrous oxide before the supercharger, supplies currently compressed air. This holds true weather condition we are talking about nitrous being pressed because it has twice the oxygen concentration as normal air or we're speaking about the nitrous air conditioning and also pressing the incoming air. The last amount of compression observed by the supercharger inlet will differ relying on the ratio of incoming air to the size of the nitrous shot, and also can result in a boost in boost of in between 0.5 to 2.5 psi!
This boost increase remains in addition to the power rise of the nitrous oxide shot therefore it can be an added 5 to 25 hp.
