Porsche 996 1000HP build
Slideshow: TCP Racing have put their Porsche knowledge and turbocharger expertise together to create this ultra-powerful daily driven 911.
TPC Racing
TPCRacing has decades of racing experience dating back to the IMSA Supercar Series of the late 1980’s and early 1990s. The team owner and driver Mike Levitas managed the turbocharger programs for various auto makes and models. TPCRacing remains active in the Porsche community where they use the team’s professional, club racing and, street Porsches to develop engine and suspension components for its partners. TPCRacing has an aggressive engineering program, focused on developing powerful superchargers and responsive shocks and dampers for professional and club sport cars.
Unassuming ride
The Porsche 996 Turbo is a rather simple looking Porsche. It's the first '911' that replaced the long standing air-cooled motors with a water cooled engine. The entire body has been revamped to look more sleek. The interior itself underwent a number of changes as well.

Big power goals
The owner of this vehicle actually had prior work done with TPC where they were able to "crank out" 700hp. Months later, he returned and asked to get the vehicle to break the power band of 1,000hp. This is a big ask for a car that is still daily driven. But, that's not to say that it can't be done. With the right combination of fuel and air and combustion, all sorts of insane power gains are attainable. The Turbo is one element that can be of great aid for this more than modest goal.

Supporting Mods
In addition to porting the heads, grinding the cams and upgrading the connecting rods were crucial to supporting the large increase in power. The timing was advanced with the cam grinding upgrades to increase valve lift/duration so that the power produced could be optimized. TPC also went with forged steel 4130 H-Beam connecting rods with high strength fasteners. They also replaced the factory studs with an upgraded stud kit. But that's not all! They also upgraded the injectors to larger 82lb units, a 5 Bar Fuel pressure regulator and a new fuel pump. The throttle body and intake plenum were upgraded to a unit from a 997 model.

Marco, Port-O!
Anybody can slap a turbo on a car and claim huge increases in horsepower. But there is an actual science to how a combustion motor works in harmony with other components to produce consistent, linear power at the crank. This Porsche underwent serious tuning from the motor to the crank. The upgrades also included porting the heads, which allows more air to enter the engine. TPC employs a wizard lead tech, Marco, who has served as a tech in the British Supercup and was responsible for porting the head on this engine to proprietary specs.

The results are in!
The company posted their Dyno results from the upgrades, and they came damn close. The engineer felt that the rear tires would produce some wheel spin on the dyno and that could prove catastrophic. As the motor was freshly built, they wanted to be keen to produce the results without risking failure. Once all the parts are broken in, there's no doubt the car will scorch the 1,000hp mark. Through this dyno, they were able to put down 843 wheel horsepower and estimate the crank hp to be 991hp. That's just 9hp short of the original goal. The customer will likely bring the car back for a re-tune and hit the milestone originally intended.
