The VF-Engineering supercharger system for the 997 Porsche is a result of 12 months of ongoing development and testing. The specification for this kit was set as:

• Bolt-on and reversible conversion 
• All hardware must fit under factory engine compartment lid 
• Non-invasive installation OEM quality 
• 6 psi with air-water intercooling 
• Hp target in the 996TT range with stock reliability and driveability

The VF-Engineering designers set about designing the billet supercharger mounting bracket with CAD software creating solid models of parts to be CNC manufactured. The bracket was designed to utilize OEM bolt patterns and requires no alteration or relocation of any engine parts to be fitted. Made from 6061-Tx aircraft grade aluminum the bracket mounts to factory machined surface points on the aluminum engine block for a precision fit.



A V3 model Vortech Engineering supercharger unit was chosen after consultation with Vortech engineers and matching the engine;s volumetric efficiency with supercharger compressor maps. The V3 unit contains helical-cut gears for super quite performance - virtually silent with the engine compartment lid closed. The V3 supercharger has a 20psi and 1000cfm maximum capacity and is an over-engineered part for this Porsche application which is geared to produce a conservative 6psi in the engine;s intake manifold.



The fastidious design of the supercharger bracket, positions the belt driven supercharger to maintain use of the OEM spring loaded belt tensioner. The serpentine belt routing was designed to maintain the correct rotation of all the accessories and maintain optimal pulley wrap for maximum friction.



The Vortech air to water intercooler (charge cooler) was integrated into the tight fit engine bay as means of reducing charged induction (boost) temperatures. Lower charge temperatures promote engine safety by reducing knock and improving the quality of the combustion cycle. Air charge (boost) from the supercharger is directed through the chargecooler core before entering the throttle body. The cooler core contains isolated channels circulating with water from a separate self contained system cooled by its own radiator. VF-Engineering integrated a Porsche OEM front radiator and front bumper vents into the kit. Water is circulated by means of an added OEM Bosch water pump through OEM Good Year water lines. Intake air temperatures in the manifold were measured to be approx 140 deg F even with ;spirited; driving at 118 deg F ambient temperatures in Arizona desert conditions mid-Summer. This dramatic drop in charge temperature helps the 997 create consistent power. For added safety the chargecooler is designed to perform continuously whilst the ignition is on.
