Product Information

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 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 996 create consistent power. For added safety the chargecooler is designed to perform continuously whilst the ignition is on.



With all major components in place the head of R&D at VF-Engineering, set about shaping the air ducts from the filter to the throttle body. The intake pipe is specially tuned for its air flow characteristics and pressure relief system. Production pipes are manufactured from a lightweight molded high temperature polymer. The thermal insulating properties of the plastic pipes prevent heat transfer into the cooled charged air traveling inside them. 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 were taken into account. The Carrera 2 and 4 test vehicles were extensively dynoed on the VF 4WD Mustang and monitored for wide band air fuel ratios at load levels often greater than would be experienced on the road. The results are an increase of 120 horsepower and 80 ft.lbs of fully useable torque.

VF Engineering VF425 Supercharger System Porsche 996 Carrera 3.4L 99-01 Reviews:
TEXT_OF_5_STARS Posted on 02/22/2011 by by Aaron A
"Hi all, I just had to write a review of this kit as I installed it in the late winter of 2010 and finished it in 2011. Its an amazing kit and I did a lot of research on it prior to purcahse. It has always been a reliable offering, but you can also see how there has been continued development throughout its life as there have been changes such as contained self oiling in the supercharger itslef from Vortech and the addition of air intake temperature sensors that allow for the best performance possible. Also in my research, it was evident that VF-E listens to their customers as they have included the best pulley size for our cars based on in-house testing and customer street use (and at times abuse!). At first I was a little shocked at all the parts and pieces, but the documentation was great and their customer service is fantastic. With time and paitence I was able to complete 100% of the installtion myself in the garage at my home. Vivid was great as well and I also decided to purchase a complete exhaust system to get the best overall performance and sound. Let's just say the first time I started the car was an epic experience. The supercharger has that *whine* we all love, but its not too extreme to be annoying. Of course, the Agency Power headers, mufflers, and SpeedTech 200 cell cats made it sound vicious! I highly recommend this kit. I think the HP gains stated here are being modest as I've heard and seen people getting much higher on the dyno with the newest version that you'll receive. Forced induction is the best way to wake up these engines. Don't get fooled by people assuming this will do huge damage either, as I talked to someone that had it on their car for over 30,000 miles with no issues! Plus I believe VF-E has over 500 Porsches on the road with this kit... I'm proud to say that I'm one of them. My two cents, is two bug thumbs up on this kit! Cheers Aaron"
