We also tested this intake on various applications from stock to upgraded hybrid turbos, and there were impressive gains for every case. In most cases where intercooler sizing becomes limited by space, a proven way to control and maintain Intake Temperatures at or below ambient temperature is to fit W/M(water/methanol) injection. In a perfect world you would want the turbo inlet outside the engine bay, exposed to direct air flow, but this is not the case.Ī high quality intercooler will offer more benefits controlling air temperatures after the turbo over a complicated cold air intake design feeding air to the turbo. In conclusion, on a turbocharged vehicle, air flow and mass feeding the turbo wins over slightly colder air temperature. If you remain stationary or moving slow in traffic, intake temperature will reach engine bay temperature, regardless of what style air intake you may use. During heavy loads and high vehicle speeds, Intake Temperature remained within 10 degree Celsius over ambient temperature. Design approved itself better than expected. Meanwhile the open filter design was the only option for a tight fitment, we decided to continue use of the OEM duct by retrofitting an AIR RAM guiding airflow directly in to the bottom of the open filter. We used the dyno to do some testing, and learned that in order to support an enclosed airbox for high HP application, size of the box is critical! Also, MAF location is very critical(a lot more in to it) Due to complexity of the design and space limitation, unfortunately the air intake position remained to be kept at the back side of the engine, and this made it very challenging to accommodate an enclosed box configuration. You may say or think of it like " hot air intake?" we did too, until further testing.įirst design for this product featured an enclosed box connected to OEM cold air feed duct (3D Printed Version). This intake supports to over 600HP without any flow restrictions while paired to MAF! Precise mounting support complementing a high quality install with an OEM plus touch. AIR RAM that connects to OEM cold air feed duct. After locating critical points for mounting and charge pipe routing, final design received a tailored Velocity Stack that blends in to the MAF. With use of modern technology, entire engine bay got 3D Scanned. Like everything else we do here, quality and functionality is fundamental for this product. We needed this product to support our R400 Turbokit as well Billet Intake Manifold as it takes all of the space from were OEM intake used to be mounted. On a heavy modified application, engine bay becomes space limited. Additional mounting bracket for automatic vehicles (Specify in the notes with your order)Īll DME found in the North American vehicles with N14/N18 engines, feature MAF (Mass Air Flow Sensor), this can not be removed thru software as it brakes down the Closed Loop operation from DME.Coupler options, 2"-2.75"- 3" (Specify in the notes with your order).PCV Retrofit Hardware(AN Fittings) for N14 or N18 engine (Specify in the notes with your order).While slight gains can be seen by pointing the velocity stack into oncoming air without the filter, this puts the engine at risk as unfiltered air can cause unwanted debris to enter your engine.This is the largest and most functional air intake that you could fit on these cars. NOTICE: Hybrid Racing recommends always running the filter on the cold air intake. Fully assembled, the filter and velocity stack has a 6.25" overall height and 7.5" diameter. The velocity stack has a 2.25" overall height. All you need to connect it to your 3" cold air intake is a 3" silicone coupler and (2) hose clamps. The velocity stack has a 6" inlet and a 3" outlet. Included in each kit is a velocity stack, filter, and a hose clamp to connect the two together. That said, the same sort of benefits can be seen by adding a similar bellmouth (in this case a velocity stack) to the end of your cold air intake. This bellmouth is added because it increases the efficiency of air moving through the pipe by as much as 70% in the right situations. ![]() ![]() If you've ever looked inside an intake manifold, you've noticed a curved "bellmouth" profile at the inlet of each intake runner. A well-designed cold air intake and high-flow cone filter are great ways to let your engine breath better, but a filter on the end of a pipe has its limitations. Paying close attention to how air flows into and out of your engine is an obvious place to start making modifications for optimal performance. ![]() When it comes to getting the most power out of your engine, the devil is in the details.
