VF Engineering Stage 2 Supercharger 8psi System Volkswagen Synchro VR6 2.9 91-98


VF Engineering

Model #VFK75-01

VF-Engineering designed this kit from the ground up using the infamous "bullet proof" Vortech Engineering supercharger unit. The key to the design of this supercharger kit is the simplicity in which it can be bolted-on. The kit is supplied with every part needed to get your car up and running supercharged on the same day. Power from the silky smooth VR6 engine is increased from 172hp to 280hp and torque from 170 ft lbs to 250 ft lbs.

The VF-Engineering approach to kit design and experience has created a bolt on kit with incredible smoothness and driveability. The Mass Air Flow sensor has been relocated and a boost overrun valve (pressure relief system) in incorporated with a "tuned" intake for optimal part throttle and off-throttle deceleration. OBD1 and OBD2 have both been fully homologated with this kit which idles and accelerates as a VR6 should - smoothly and relentlessly.

This kit requires the replacement of the OEM injectors with direct drop-in Bosch injectors supplied. The boost is increased and race bypass valve is included, giving a "whistle" sound on deceleration. The additional hp makes mid-range acceleration more aggressive, and when launching, makes you want to hold onto something!

Performance, reliability, and stock feel are major factors in the extensive R&D carried by VF-Engineering in Europe and the USA. The custom proprietary VF. VF software supplied with this kit safely re-aligns all fueling and engine management parameters. Unlike other forced induction solutions, VF-Engineering s kit is designed to work safely within Volkswagen s OEM parameters thus minimizing the likelihood of spurious DTCs (Diagnostic Trouble Codes) or Check-Engine Lights.

Every aspect of this kit has been fully engineered for high quality fitment and highly demanding performance and expectation. VF s in-house horizontal, turning and milling CNC s and plastic molding plant, VF s industry reputation and track record, and Vortech s reliability have been fully exploited to create a product with internationally unrivaled material technology, quality, and performance.

Not all chassis dynos produce comparable results which is why it is important to consider the "delta", or relative power increase, measured on the same dyno before and after modification. Power gains shown by VF have been found to be accurate on test vehicles on 91 octane, with stock setups (i.e. throttle body, exhaust system, cams, etc.). The VF software adapts just as the OEM software and a slight increase in performance may be expected from the use of higher quality fuels such as 93 octane.

The unique advantage of all VF-Engineering products is the 1 year unlimited mileage warranty coupled with lifetime software support and world renowned customer service. VF-Engineering has been supercharging the VR6 since 1993 and have sold over 1000 kits to-date. This is a proven product.
