Design
The factory intake system of the BMW M2 N55 system is not a sealed design. The front opening attaches directly the front inlet which is in turn attached to the front air ducts located behind the grills and there is a second opening which opens into the engine bay towards the headlight. This clearly suggests that one opening is not enough and the engineers had to create a separate opening to meet the high airflow demands of the engine which is understandable since the front intake has barely the same cross sectional area as the MAF. The design is still however efficient as far as keeping the intake air temperatures low. As far as being an ultimate performance intake, it is most certainly not with it's angular design, small volume and having an airflow with a directional path which is not direct.
For this application we have opted for large cross sectional turbo inlet tube with integrated MAF and a smooth non concentric expanding inlet tube which with silicone couplers. The expanding large volume inlet tube acts like a large velocity stack which accelerates the airflow and is much larger than the small and short velocity stack fitted to the internals of the oem intake. The result of the smoother airflow from our inlet tube is a far smoother lower rpm torque availability from the engine vastly improving drivability. Throttle response is immediately felt to be smoother and more eager.The inlet tube is attached via a stainless steel v band clamp to the air filter housing which attaches directly to the oem front air feed and has a frontal opening facing towards the headlight.
High Flow Air Filters & Intake Temperatures
Within this beautifully shaped carbon shaped enclosure sits our bespoke short stack high surface area filter larger than any cone filter design currently on offer on the market with a huge opening of 170mm (6 3/4") and is designed to take full advantage of the intake tube by altering the direction of the airflow towards the outer walls. By placing the air filter in front of the inlet tube we achieve the largest velocity stack ever seen for the N55 and which also has the best laminar flow. It is important to note that we have painstakingly opted for the largest possible air filter for a various number of reasons. Not only does a larger air filter allow for more air flow and therefore power but it also does not block up for longer and continues to be efficient at it's main purpose which is to filter the air of harmful elements.The air filter is completely encapsulated within the air filter housing rejecting the vast majority of the engine bay hot air and with the angle of the front inlet the air circulates around the air filter giving an even distribution of outside cool air.
PERFORMANCE TESTING
Dyno tests were performed under strict controlled conditions on a Dyno Dynamics machine in order to show a true and realistic result.Directly inline with the on-road driving experience and a very realistic result. Engine produces more torque initially which is directly related to the improved flow characteristics of the inlet tube allowing the turbo to spool up faster. No gain expected in the midrange as the stock intake system flows enough in this region. After 4900rpm the power gain increases all the way to redline. It's important to point out that fabricated dyno graphs tend to show a similar dyno curve shape but just higher across the rpm range. Here we can see the two graphs are almost exactly the same from 2800-4900rpm and the gains are at the higher rpm where the stock system becomes a restriction. These are wheel horsepower results. Flywheel estimation would be a realistic + 16-18HP.
