As we’ve discussed in previous articles there’s however the possibility of porting the factory supercharger for a 10 to 15% obtain in capacity (which in this case would be yet another 23 to 35 horsepower). There is also the possibility of retrofitting a larger supercharger including the Eaton M62 to achieve possible up to around 300hp depending on the final selection of a supercharger nangs delivery.
This change way (porting or replacing the factory supercharger) can prove to be complicated and expensive, especially if the supercharger is integrated into the absorption manifold (and possibly an air to water intercooler) because the event is by using several factory supercharged cars. A probable sensible answer for this case is to utilize nitrous oxide injection to complement the power distribution when racing, and being satisfied with a reliable lower powered car once the nitrous is off and we’re perhaps not racing.
The reason why nitrous oxide (N2O) becomes a good power adder is twofold: Nitrous is cheap in terms of horsepower per money moves, and particularly in the scenarios wherever we are already supercharged and therefore will only be deploying it on the unusual occasions when we do strike the track.
Nitrous oxide is a great’chiller’since it comes out from the bottle at a temperature of negative 127*F and is capable of chilling the overall supercharged air charge mixture by over 100*F as described by enthusiasts, this really is one more heat decrease over the effects of whatsoever intercooler you’ve fitted. This in-fact makes nitrous a great proposal for vehicles that have presently maxed out their superchargers, where in fact the supercharger is running at top rpms and providing very good outlet temperatures. The nitrous oxide shot can effortlessly increase the thermal performance of the supercharger when it’s many stressed out and give people a wonderful, cool, and heavy mixture.
Nitrous oxide energy distribution is pretty straight forward to setup and to tune, especially on newer model vehicles with return-les gas techniques, or difficult to crack computers that make it hard to update (and properly tune) a much bigger supercharger setup. Nitrous oxide gas delivery can be set-up completely individually from the OEM ECU and gas program and hence makes nitrous a possible program for German cars with persistent computers.
This can be a racer technique… many vehicles look to execute greater throughout the wintertime months since the air is cooler, power is increased, and the paths while cool, may be ready for grip and may heat up enough during the night to allow for footing and to provide people the capability to use the cold heavy air to post their best situations of the year. As the weather gets hotter, traction increases as the asphalt is hot and difficult, but horsepower is paid down as a result of warmer, less thick air. Usually racers realize that their vehicles range inside their fraction mile efficiency by as much as a half a 2nd between their summertime tune and their winter song, particularly when you are employing a supercharger or turbocharger that squeezes (and further heats) the incoming air.
The clear answer to on-track reliability, racers have found, is to combine the usage of nitrous oxide (which is summer friendly) with pushed induction (superchargers and turbochargers) which are cold weather friendly. In the summer time, the exterior heat is high, and therefore the nitrous container stress is preserved at a advanced over 1100 psi. This permits for a large nitrous movement rate beneath the experienced force (even with no package heater) which gives good summer efficiency for nitrous helped cars. Within the cold temperatures, the exterior conditions drop somewhat, the nitrous in the container agreements and the container pressure falls, eventually, the nitrous movement rate drops and nitrous aided cars show worse efficiency in the wintertime times.
The whole opposite does work for supercharged cars that create great horsepower in the winter from compressing great thick air, and bad power in the summer heat. Whenever you combine those two energy adders you get fairly flat and consistent power manufacturing year-round since the supercharger shines when the nitrous is weak, and the nitrous shines when the supercharger is weak, and thus together, they offer consistent energy offer year round.
