HPF Turbo BMW M3: White Heat
With the world markets changing and most contracting, there are still some companies pushing the envelope and continuing to grow and innovate during these challenging times. The aftermarket performance arena is no exception. With the demand for performance product shrinking following a 1-2 punch with the high price of gas followed by a global recession, those that continue to innovate and spend money through these challenging times are coming out on top.
Chris Bergemann, the President of Horsepowerfreaks (HPF) is one example. In a short time frame, the President of Horsepower Freaks Performance (HPF) has reached several milestones of performance by investing in his company. It seems only recently they broke 600, then 700 but this time they should have the record firmed up for a while. This Entrepreneur Magazine's 268th Fastest Growing Company in America has defined how much horsepower can be extracted from BMW's 3.2L mill. And that new number is over 1100hp.
Bergemann started with the stout iron block extracted from a 2002 E46 M3. This 3.2L inline-6 produces 333 NA horsepower so it's blessed with a design that will only help move air with forced induction added. Starting with the head treatment, many readers will be surprised to hear what Bergemann revealed. Nothing has been done to it. It has no port and polishing and retains stock valvetrain, cams and cam gears. "No need for anything fancy," Bergemann admits "this thing has huge ports and double VANOS, so its good to go. Hell, it even has a stock headgasket." The bottom end however, is a different piece of work. The bottom end has been strengthened with HPF components: pistons, rings, connecting rods and crank treatment but their details are murky. Bergemann will not disclose any details about these components because they are propriety. HPF produces highest horsepower around and they aren't about to give their competition any hints on how they did it. The competition will just have to spend time and money reverse engineering if they want to decode the mystery of 1100 usable ponies.
These horsepower figures aren't attained by a built motor alone because at the heart of every HPF car is a big turbo. In the case of this car, HPF deployed the Precision HPS76 dual ball-bearing turbo connected to a network of HPF lines to cool and lubricate. HPF oil scavenge pump is connected to HPF oil feed lines while HPF coolant lines direct the water. To feed the beast, the combustion chamber needed more fuel and lots of it. Fuel is drawn in with three pumps: a factory unit and twin Walbro 255lph inline pumps. The pressure is regulated by an AEM FPR before meeting up with an HPF fuel rail connected to six 1200cc RC Engineering injectors. Ignition comes from AEM's Twin Fire ignition system and stock coils blazing up Denso Iridium plugs. While the air is drawn in with a HPF intake and piped post-compression into an HPF front mount intercooler, piping and silicone couplers while being vented with twin HKS SSQV blow-off valves. The air charge slams into the HPF cast aluminum manifold with integrated methanol injection. The FJO methanol injection system keeps the exhaust gas temps low, so the boost can be cranked, timing advanced and horsepower levels set to: Freak. The boost is regulated with a TiAL 44mm wastegate and dumped into a HPF Stage III 4-inch exhaust with a tone that sends a clear message for other cars to pull to the right. HPF set out to design an engine management system to make this mechanical masterpiece work. Based on the AEM EMS box, the HPF system takes control of everything needed to keep this car tamed. The HPF engine management system features speed-based boost control, traction control with a controller inside cabin, methanol control and switched maps for pump gas, race fuel and methanol. The EMS also controls the oil scavenge pump, methanol activation and a safety methanol line pressure switch drops to low boost when outside of safety range. When the dust settled the numbers were in and the Horsepower freaks were proud to share with us they made 902whp with 679ft-lbs of ground-pounding torque.
All that power needed to be properly harnessed to prevent failure. So HPF turned to Japanese driveline spcialists, OS Giken for one of their triple plate iclutches. Combined with a lightweight flywheel, the OS Giken unit spins up a factory driveshaft, LSD and even axles. A true testament to BMWs ability to build stout driveline components, the 6-speed transmission is totally stock!
Over the course of the two year buildup, Bergemann left little untouched. If it was left factory, it was because the stock components were so capable.
