Advanced Compressor Stage
Here's where the rubber meets the road. Vortech's compressor stages are highly evolved, thoroughly tested designs, resulting from more than 15 years of experience and thousands of production supercharger units. A simple visual examination clearly shows the difference. All Vortech compressors incorporate sophisticated impeller designs, coupled to a vaneless diffuser, with a progressive scroll, or volute exit stage. Impellers employ advanced aerodynamic features such as optimized inducer blading, splitters, and in some cases, exit rake and backsweep... all depending on the particular pressure/flow objectives. Rather than a simple change of blower speed to effect different "models", each Vortech supercharger is optimized aerodynamically so that best performance is attained for a specific vehicle application.
In order to effectively take advantage of impeller work, flow must be efficiently diffused so that pressure rise can be generated with minimal losses. Unfortunately, a simple "cut-and-paste" won't work. Instead, the diffuser is optimally matched to the impeller flow physics, with many iterations tested and verified until maximum efficiency is achieved with each supercharger design. Finally, a matched volute effectively collects and diffuses further, resulting in additional pressure rise. The result? Isentropic efficiencies as high as 80%! In fact, all Vortech compressors achieve at least 72% peak efficiency, with better than 65% efficiency achieved over a majority of design flow range (surge to choke).
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 turbomachinery components for the most demanding applications proves its durability.
Drive Gear
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
Vortech offers both engine-oil-fed and internally lubricated superchargers. V-3 units are factory prefilled with our special synthetic fluid - no oil lines necessary. All other units are lubricated by engine oil that is pre-filtered and injected directly onto the drive gears.
