If you’ve been reading the Motorator Blog, then you’ve certainly heard of Techco, a new performance automotive parts manufacturer started by several former employees of Saleen. Techco offers ultra-high performance parts and accessories for today’s modern muscle cars. Their latest offering is a new supercharger for C6 Corvettes.



Techco has designed and engineered a reverse-revolution, twin-screw supercharger completely in-house. Using a modular design, the Techco supercharged was created to adapt to several different vehicles by only changing a few key pieces, such as the induction and intake manifold mounting locations.

Techco’s new supercharger kit for all 2005-Current (C6) Corvettes equipped with the LS2, LS3 or LS7 V8s, features reverse rotor lobes to allow front inlet induction for a shorter, more direct passage of air into the supercharger, resulting in cooler air and higher volumetric efficiency. This revolutionary supercharger made its debut in a supercharger kit for Dodge/Chrysler 5.7-liter and 6.1-liter V8s last year, followed by an application for Ford Mustang 4.6-liter 3-valve V8s in February 2009.



Like the Ford and Dodge/Chrysler designs, the Techco supercharger kit for the Corvette combines a large displacement blower with an ingenious dual-stage intercooler system featuring single-pass coolant flow. The Techco supercharger’s 3.0-liter’s of displacement is the largest among all Corvette twin-screws, pumping approximately 50 percent more air into each cylinder during every intake stroke. This highly efficient design produces the most horsepower and torque per psi of boost pressure (6 psi) of any supercharger on the market today, approximately 600 bhp/535 lb-ft versus the stock Corvette V8’s 430 bhp/424 lb-ft. And it fits neatly and cleanly under the stock Corvette hood.



What makes the Techco 3.0-liter Reverse-Revolution, Twin-Screw Supercharger so revolutionary is the unique design (patent pending), which optimizes airflow efficiency throughout. Incoming air is fed into the front of the supercharger, not the back like conventional designs. This ensures that the incoming air has minimal turns, eliminating restrictions, before entering into the supercharger housing. Additionally, without the need for a complex inlet tube, the largest possible orifice size is maintained, maximizing airflow efficiencies. The air then flows into the lobes of the Reverse-Revolution, asymmetric multi-lobe compressor screws, where it is compressed, not merely moved, as in other forms of supercharging. The compressed air then flows into the intercooler housing, which contains two intercoolers, mounted in an A-frame configuration to ensure the airflow is evenly distributed to each runner bank. The patent pending Twin Intercooler design results in higher cooling capacity and greater thermal efficiencies as the cooling water only has to pass through the intercoolers once, keeping the charge air cool.



A further benefit of the front Inlet Design is the additional package space above the supercharger that is used for long high flow Intake Runners, which increases low-end torque. The resulting design of the Techco Reverse-Revolution, Twin-Screw Supercharger allows air to move through the supercharger quickly and efficiently, without significant heat buildup, and at the highest resulting airflow volume and air density at low boost output. The performance result is maximized horsepower and torque output.



The Techco Corvette Supercharger kit is complete with the Reverse-Revolution, Twin-Screw Compressor, front inlet induction with integrated bypass, dual stage intercooler, open element cold air kit, 110mm billet aluminum mass air flow sensor, extruded aluminum fuel rails, 54 lb/hr fuel injectors, 8-rid front accessory drive with 2-piece harmonic balancer, Diablosport Predator flash programmer with Techco calibration, and detail instruction manual.



For extreme power-hungry enthusiasts, Techco is also offering Optional Boost Upgrade Kits (starting at 10 psi), which offer increased power output from 650 bhp on up.

Pricing for the Techco C6 Corvette Supercharger is about $8,500 (base kit), with an optional polished kit upgrade for an additional $1,500.
