Supercharging your E46 325i/325ci/325xi is the best and easiest way to make more power. A VF supercharger kit for the E46 325 adds 100hp and over 50ft-lbs of torque in a bolt-on package that can be installed over a weekend! The VF kit is an all-inclusive kit that comes ready to install:
- Expected gains: +101hp / + 56ft-lbs
- Vortech supercharger
- Hard anodized aluminum and Chromoly bracket
- Polypropylene air intake piping
- K&N filter
- Bigger fuel injectors
- Emissions-friendly crankcase vent system
- Bosch overboost bypass circuit
- VF Hex Tuning software (mail-in flash or optional tuning cable)
The software calibrations have been carried out on multiple test cars in a variety of weather and atmospheric conditions. VF disassembled the stock ECU software, re-wrote it using their own maps and algorithms, and tuned the 325i specifically for their Vortech supercharger. Boost is set at 6psi but thanks to VF software tuning the expected gains are the same, or more, than kits running greater boost. The goal was better-than-factory drivability and smoothness with more power in the mid-high RPM range.
The VF 325 kit has been designed to run from the stock serpentine belt layout but with a longer OEM-style belt. This retains the use of the stock belt tensioner assembly so there is no need to manually tension the belt or run into belt slipping issues. All intake ducts are molded from polypropylene plastic for smooth airflow and light weight. All major components are finished in stealthy black anodize or dye for an OEM appearance.
VF is one of the leading Vortech supercharger kit manufacturers in the world. Their expertise has been applied to BMWs as well as Lamborghinis and Audis with unmatched quality and results. All components are backed by a one year warranty. Comprehensive installation instructions are included with an expected install time of approximately 8 hours. The kit is fully reversible to restore the car back to stock. The ECU retains full OBD communication and the kit is 49-state legal (not CARB approved). All major components are Made in California.
There is simply no easier way to 100hp gains that is less intrusive and retains OEM functionality of other systems. S54 swaps may have an OE appeal but requires a long parts list and specific expertise in BMW electronics to complete. And thorough care and attention to detail are required to reach a level of OE factory fit and finish without looking sloppy and unprofessional. All of that is not an issue with a VF supercharger kit that looks and performs like it was installed on the production line in Munich.
