Proven Performance

Vortech superchargers operate on fundamental and proven turbomachinery principles, first described by Euler's turbomachinery equation developed in the 18th Century. This principle states that the work imparted to a fluid by an impeller is related to the change in angular momentum of the fluid. From these humble beginnings, the centrifugal compressor has evolved and found its way to becoming the most efficient and reliable means for delivering charge air at high pressures. Vortech has developed its line of centrifugal superchargers to a performance level that clearly establishes Vortech as the performance and technology leader in aftermarket supercharging.

Componentry

Vortech componentry has garnered a reputation for its "best in class" execution. Blower casing components are cast from A356 aircraft spec aluminium alloy treated to T-6 condition. Modern CNC production cells ensure that part tolerances are held into the "tenths" - to, and in many cases beyond aircraft tolerances.

Impeller

The heart of any centrifugal supercharger is the impeller. Our piece is investment cast from an extremely strong but light-weight proprietary aluminium alloy (similar to that used in turbochargers). This special heat treated material is used because of its stability and enhanced properties at the high operating temperatures... which may reach 400°F under extreme conditions. At this temperature, the Vortech impeller is up to 36% stronger than even 7075, a common structural aluminium material used by others. The investment cast process secures close dimensional tolerance and excellent surface finish. Of course, 100% CNC machining ensures exact tolerances. And finally, multi-plane dynamic balancing to better than ISO G0.4 tolerances delivers smooth operation. The historical use of these same procedures in building aircraft turbomachinery components for the most demanding applications proves its durability.

Drive Gears

Drive gears are manufactured from 8620 and 9310 carburized billet alloy steels. These premium grade materials possess exceptional strength and durability, with enhanced core toughness properties. The gear teeth are CNC precision ground. The internal step-up drive system is engineered to reliably support impeller speeds exceeding 70,000 rpm.

Bearings

Vortech bearings are ultra-high precision (ABEC 7/ABEC 9) pieces that are made in the USA. Most are custom manufactured to our specifications. Aircraft quality is truly an understatement here, since these bearings experience speeds as much as twice that of a jet engine.

Lubrication System

The maintenance free lubrication system uses engine oil that is pre-filtered and injected directly onto the drive gears. We chose this configuration as opposed to a common "self-contained" set-up because engine oil provides faster warm-up, excellent reliability and superior cooling. The lubricating oil benefits from continuous filtration, being routinely changed along with the engine oil (instead of an additional maintenance action). This system also offers the best opportunity for thermally stable operation. Vortech firmly believes this is the best method to feed and care for superchargers.
