COMPONENTRY
Vortech componentry has garnered a reputation for its "best in class" execution.
Blower casing components are cast from A356 aircraft-spec aluminum 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 aluminum
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 aluminum 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 turbo machinery
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.
