Porsche 997 Supercharger System
From the outset, this supercharger system was engineered to have a precision factory look and feel. The engineers set about designing the billet manufactured supercharger mounting bracket with CAD software creating solid models of parts to be CNC manufactured. The bracket was designed to utilise OEM bolt patterns and requires no alteration or relocation of any engine parts to be fitted. Made from 6061-T6 aircraft grade aluminium the bracket mounts to factory machined surface points on the aluminium engine block for a precision fit.
A V3 model Si-Trim Vortech Engineering supercharger unit was chosen after carefully matching the engine’s volumetric efficiency to the available supercharger compressor maps. The V3 supercharger features helical-cut gears for quiet operation – it’s virtually silent with the engine compartment lid closed. The V3 supercharger is more than capable having a 20psi and 1000cfm maximum capacity, so is an over-engineered part for this Porsche application which is specified to produce a conservative 6psi at the engine’s intake manifold.
The Vortech air to water intercooler (charge cooler) is integrated into the tight fit engine bay as the means of reducing charged air (boost) temperatures. Lower charge temperatures promote engine safety by increasing the knock limit and improving performance by increasing the air density available to the engine. Air charge (boost) from the supercharger is directed through the charge cooler 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. A Porsche OEM front radiator and front bumper vents into the kit for cooling purposes. 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 only 60 deg C even with ‘spirited’ driving, with 48 deg C ambient temperatures in Arizona desert conditions mid-Summer. That’s impressive! This dramatic drop in charge temperature helps the 997 create consistent power. For added safety, the charge cooler is designed to perform continuously whilst the ignition is on.
Engine management software was by written by VF with extensive testing performed on independent test cars. Multiple factors such as charge air temperatures, ignition timing, fuel trims, maps and injector performance are optimised. The Carrera 2 and 4 test vehicles went through vigorous and rigorous dyno testing prior to validation and sign-off. The yield is an impressive increase of 150 horsepower and 90 ft.lbs of fully usable torque, bringing the 3.6-litre engine up to 480hp/370 ft-lbs, and the 3.8-litre engine up to 510hp/380 ft-lbs.
