Case in point is Chris Bergemann, the owner of HorsepowerFreaks (HPF) who has been continually setting the bar for E46 M3 performance. For critics who may be wondering why Bergemann has bagged his second PAS Magazine cover in 18 months, the answer is obvious; this completely new car is every bit as visually appealing as the last one, but with performance that would embarrass his previous wild creations.

The car was stripped of several hundred pounds of excess weight thanks to HPF. Nearly 40 man hours were spent stripping the chassis harness of all non-essential items or swapping OEM stuff for lighter gear. Even with the added weight of the cage, wing, widebody and turbo kit, the M3 weighed in at a scant 3,127 lbs. With the driver in the driver’s seat, the car now has near perfect 50:50 weight distribution.

One of the most important aspects of every car built for the track is traction and loads of it. HPF chose VIP Modular for their extremely strong and lightweight wheels. The 19x10 and 19x13-inch wheels were custom built and feature a gloss black lip and matte finish on the center. VIP Modular even etched the letters “HPF” directly onto each wheel. Wrapped in Hoosier R6 265 slicks in the front and 325s in the rear, all of the necessary traction is there.

The entire chassis was dramatically stiffened with a custom gusseted roll-cage built and installed by Racetech Motorsports. The interior was stuffed with Sparco Circuit Pro race seats and RCI 5-point seat belts. HPF retained the factory dash and modified it to fit within the roll-cage constraints to keep the BMW feel. The steering wheel is a Vertex which easily disconnects from the Rothsport Racing quick release hub. To monitor engine parameters, this beast was equipped with an AEM fuel pressure gauge, AEM oil pressure gauge, AEM boost gauge and an AEM wideband.

Running the fully built HPF S54 engine, the block was bored and plateau-brushed using state of the art Sunnen equipment. It was then balanced and stuffed with HPF-spec pistons, rods, main studs, wrist pins, rings and bearings all done by M&B Cylinder Heads. The stock S54 heads flow so well, that HPF didn’t need to massage or modify the head or even the cams, but it did require ARP L19 studs to clamp it down. The S54 utilizes dual VANOS technology that allows HPF to position the camshafts + or – 20 degrees for every rpm and every boost level, giving all kinds of timing adjustability along with the drivability of a grocery getter.

Bergemann’s M3 was tailored specifically for the track with their stage 3 turbo system that makes over 800rwhp when the button is pressed and 650rwhp when the button isn’t pressed. The HPF magic button is right by the steering wheel and switches maps when the driver wants an additional 150rwhp on those long straights to pass everything and everyone. To hold the power, HPF turned to JDM manufacturer OS Giken and their triple carbon clutch. The clutch handles all the power with ease. To enhance the look of the engine, an HPF carbon fiber engine cover was installed.
