The core of the ScienceofSpeed Supercharger System is the big bore twin screw compressor that displaces 2.1L of volume per revolution. Increasing displacement of a positive displacement supercharger usually results in an increase of the supercharger length resulting in an increase of parasitic loss and heat. This compressor displaces 2.1L of volume yet has screws and a housing that is comparable to a 1.7L Autorotor or 1.6L Lysholm/Whipple compressor. Manufacture's testing has shown that this compressor requires 15 hp less to operate and produces a discharge temperature 20 degrees lower than similar Autorotor/Lysholm/Whipple compressors of the same volume.
In short, this compressor produces 20% more volume with out an increase in power required to drive it. More volume at every RPM with out increased parasitic loss means increased power at every RPM from tip-in to redline. In fact, the system produces 5-6 PSI of pressure at only 2500 RPM resulting in instant on throttle response.
This compressor features a billet housing for increased rigidity and a strengthened bearing design for the rotors. This updated bearing design results in the compressor being nearly silent at idle and under load. The compressor is much quieter than other twin screw compressors we have ever tested with.
fuel & ignition system:
The ScienceofSpeed Supercharger System includes the AEM Series 2 (1991-94) or AEM Fuel/Ignition Controller (1995-05) to provide direct control over the included upgraded injectors and ignition control. A plug-and-play harness means no modification to the factory electrical harness is required. A base calibration is included that gets you up and running and ready for dyno tuning.
The ScienceofSpeed Supercharger System includes a rigid tensioner that improves belt traction under load.
system design & reliability:
This system is advanced cast / CNC machined aluminum inlet and intake manifolds that allow a screw type supercharger to be bolted to the NSX engine. This design is incredibly durable and has years of proven reliability.
Our system requires no modifications including cutting, drilling, or modifying of any factory sheet metal components. The installation is straight forward, well documented, and offers 100% reversibility.
Our tuning system is powerful, yet offers reliable trouble free operation. The system requires dynamometer fine tuning once installed (as every forced induction system should require) yet once tuned never requires adjustment. With a built in MAP sensor, the system adjusts to varying air density changes being elevation or climate related.
