"Telling the truth about power output is very important for us, even if customers ask why our numbers are slightly smaller than those claimed by our rivals. We spend a lot of time explaining to would-be clients that our numbers are real and reproducible, and that their cars will be fast and drivable in the real world where it counts."
Another objective was creating parts that could be sold worldwide and easily fitted by any competent shop or even an experienced DIY mechanic owner. At the same time, other than the ECU remapping, servicing can be carried out normally, so you don't need to bring the car back to Champion for service.
The F77 engine upgrade package starts with the carbon airbox. A slightly larger than stock 82mm carbon Y-pipe is linked to a bored-out 82mm throttle body and T-pipe. This combination gives a worthwhile power increase, even when used with the stock turbos.Werks One offers two different exhaust systems for the Turbo, both made in Italy by Tubi Style. The first is a road system with 200-cell metal catalysts; the one fitted to this car is a race setup with no catalysts and inconel tubular headers with full merge collectors.
The Werks One Turbo uses a blow-off valve physically separate from the turbo housing, and the same unit will fit both generations of the 997 Turbo motor with just slightly different CNC machining on the housing. These parts can even be anodized in different colors if the customer so wishes.
The factory VTG turbos have an inherent power ceiling around 550 hp, so Werks One set out to build a bespoke unit with a 63.5mm billet compressor wheel for higher output applications. "We have a few prototype units out there on customer cars to test the bearings in everyday conditions," Milone says. "So far they have performed perfectly."
The Werks One high efficiency intercooler is Naveen's favorite component. He enthusiastically led me to the room behind the workshop where these bespoke intercooler arrays are assembled. The engineers found a way to increase the surface area for a given physical size of intercooler, and the statistics are eye opening. The core of a Werks One intercooler has 36 percent higher volume, with 40 percent greater flow capacity, while its cast aluminum end tanks have 220 percent greater volume on the inlet side and 75 percent more volume on the outlet end.
These numbers achieve an inlet temperature reduction of up to 50°F. This means the Werks One Turbo doesn't have to run boost as high as some rivals for the same power, which is good news, especially when ambient temperatures are high.
It also means the engine can safely sustain higher boost pressures, and more aggressive ignition timing can be dialed in at low rpm for even better response. ECU mapping is done by GIAC in California.
Where a stock Turbo has 480 hp at 6000 rpm and 460 lb-ft of torque from 1950 to 5000 rpm, the K1 Turbo boasts 658 hp at 6650 rpm with 631 lb-ft at 3450 rpm. GIAC has a map for the Turbo Tiptronic too.
The team initially experimented with some off-the-shelf uprated suspension solutions. "We tried a nice KW setup that Olaf Manthey put together for us, but found that it did not suit our local roads," Maraj says. "We ended up with custom coilovers using H&R springs and spring perches with stock damper inserts, 997 GT3 Cup front and rear control arms, RSR spherical bearings and H&R 26mm front and 24mm rear adjustable anti-roll bars, and a front strut brace."
The elegant multi-spoke lightweight alloy wheels filling out the arches are Champion Motorsport's Forged Magnesium MS61 design in 9.0x19 and 12.0x19-inch sizes, shod with 235/35 and 305/30 Pilot Sport Cup tires. These feature a black satin finish to contrast with the gray paintwork. The lightweight theme is underlined by a set of Poggipolini titanium wheel bolts.
