How does it work?
Our system mates a high-output (~ 7 horsepower @ 100,000 rpm) permanent magnet brushless motor to the compressor side of a traditional turbocharger. The system is capable of boosting the pressure of ambient air at the required flow rates to significantly increase power output of small to medium displacement engines throughout their rev range.
How much boost does this thing actually make?
As a completely objective performance characteristic, below is a map of boost pressure vs. air flow as measured in PSI and CFM, respectively.
This model can be applied to any internal combustion engine. As an example, take a MX-5 Miata’s naturally aspirated 2.0 L 4 cylinder engine. At 6000 RPM naturally aspirated, the engine is pumping approximately 180 CFM of air through its intake manifold. As boost inherently increases CFM (the entire mission of forced induction) a function is needed to map boost to full throttle RPM. Below is an adjusted boost and power increase vs full throttle RPM. Note: this model assumes ideal intercooling between the compressor and intake manifold for % power increase.
What are the risks?
Installing our supercharger should be done at your own risk. Many engines required supporting mods for increased power outputs. Engine tuning is inherently a risky business and ARC Superchargers is not liable if you cause damage to your engine from the installation of our kit. However, unlike a traditional turbocharger conversion, the modifications required to install our system are significantly less and completely reversible.
Most electric superchargers I’ve seen are scams. What is the difference with yours?
Power and geometry. The stereotypical electric supercharger you’d find listed on ebay is likely a few dozen watt bilge fume fan that runs off of a car’s 12V. Installing a unit like this will more likely than not just add a restriction to the car’s intake. The motor used in our system draws several Kilowatts! Serious power that is 50X – 250X the output from ebay “solutions”. Anything drawing currently directly from a vehicle’s 12V rail is not going to be able to push the amount of air required by an engine. Additionally, the fan structure on the ebay kits is usually a bent sheet metal single stage design that is unable to develop any static pressure difference. Our solution utilizes a TD06-20G style Aluminum compressor and housing common among existing exhaust driven turbochargers.
