We are proud to announce the release of STILLEN's supercharger for the VQ37 engine.  Some of the most important factors in the development were hood clearance, CARB legality, air to water intercooler, reliability, and obviously performance. We feel that STILLEN have met or exceeded each of these goals.

When looking at different forms of forced induction the engineering team at STILLEN decided that the best  supercharge design for this application would be a centrifugal type.  One of the great things about the Vortech supercharger is the ease of installation as well as the ability to easily add more boost and increase power. The engineers at STILLEN also wanted a supercharger system that offered little maintenance needs, so the ultimate decision was made for the V-3 series supercharger.

The Vortech V-3 series supercharger uses a self-contained lubrication system. That means no need for running additional lines from the oil pan or separate coolers. Simply bolt on the blower and you're good to go. Oil changes are very easy with the drain tube located on the bottom of the blower and the fill tube located on top. Changing the oil in the supercharger itself is a quick ten minute job.

One of the most important aspects of supercharging is also cooling. Superchargers build a lot of heat during the compression process so the air needs to be cooled  prior to entering the engine in order to obtain maximum performance. To do this STILLEN designed a cast aluminum intake manifold which houses an air-to-water intercooler which  drops intake charge over 100 degrees.  Air-to-water intercoolers have been proven to be the most efficient intercoolers available. The intercooler system uses its own separate coolant path that does not get routed in with the engine coolant.  An added benefit to the air-to-water intercooler design is that the heat exchanger (mounted in front of the radiator to cool the coolant) is very thin.  To reduce the risk of overheating STILLEN have strategically placed the heat exchanger and intakes to ensure that we have sufficient air flow to all of the vital components and additional coolers without impeding airflow to the radiator.

Airflow was another major consideration for the supercharger system. Because even stock G37's are seeing increased oil temperatures in just a few laps around a race course, STILLEN wanted to make sure that the heat exchanger and intakes did not interfere with our other coolers. We are very excited to confirm that the STILLEN race oil cooler, automatic transmission cooler, and power steering cooler all fit perfectly together. To bring the air into the intake path we have chosen to go with a Y-pipe designed cast aluminum intake tube that relocate the MAF sensors, retaining a "draw through" configuration. This means that the MAF sensor are located in front of the forced induction device to get an accurate reading of air volume. We chose to do this because this is what NISSAN recommends. During STILLEN's many years of building superchargers for NISSAN vehicles as well as their great working relationship with NISSAN, they have learned that the MAF sensor that NISSAN uses is not designed to be "blown through", or post forced induction. Example of this are the two NISSAN vehicles that use forced induction from the factory. The NISSAN GT-R and the 300ZX. Both cars use a draw through MAF sensor setup.

At the end of the day, the most important aspect of any forced induction system is "Performance." Performance is more than dyno numbers or horsepower claims. Performance means, how does it "perform" at a race track? How does it "perform" in daily driving conditions? STILLEN tested an Infiniti G37 equipped with their race oil cooler and auto trans cooler.  Track testing consisted of multiple 0-140mph runs and hard driving on a very tight course with plenty of revving and redlining. They then  parked the car for five minutes to let everything heatsoak and get really warm then immediately ran another series of 0-140 mph runs. The car was able to handle these extreme tests.  During those tests we had numerous data logging devices inside the car keeping track of a number of different data points.
