Porsche Boxster, Cayman, GT4 981 Header & Sport CatIndividual Long Tube Manifold with 200 cell substrate to allow easier flow of exhaust gases, which in turns allows greater power output.Made from heat resisting stainless steel 1.4828 (T309 (1.4828)). Welded and polished by hand.
The TPC 950 turbo system is the ultimate in proven reliability upgrade for your Porsche 991/GT2 Porsche. Whats included 304 stainless headers w/CNC flanges and wastegate plumbing, Garrett G series turbos, Tial Wastegates, Complete oil / water hydraulic lines and fittings, CNC exhaust discharge adapters to allow use of original exhaust. The TPC 950 turbo system is designed to be used on a stock engine with no modifications. The TPC 950 Turbo system is tuned and designed exclusively to be used in conjunction with TPC intercooler system / Y pipe, TPC dual path GT2 exhaust and Cobb AP (NOT INCLUDED IN TURBO SYSTEM TO BE PURCHASED SEPARATELY) .Our TPC Turbo system has proven reliability in racing applications as used on our Optima Battery Search for the Ultimate Street Car GT2RSx and the OFFICIAL LAND SPEED RECORD for the 991 Turbo. The heart of the TPC 950 system is based on the latest in turbo technology featuring the new "G" series Garrett Turbo family. The new G series features the most modern turbine section allowing ridiculous performance with no compromise to the torque curve (Note the torque curve in the graph above) this is what wins races. The compressor section features a 54 mm inducer which allows 55 lb/hr @ 2.5 pressure ratio @ 72% eff . We have designed the system for use with the stock engine and have tuned the power band at modest manifold pressures not allowing torque to go over 600 ft/lb until after 4800 rpm peak torque is at 6400 rpm peake HP is at the last RPM site as per a proper race engine. Suggested options for the TPC 950 system is the Plex tuning boost controller, Dodson clutch, DSC Sport controller for added grip.
This turbo system comes complete with the following:
- 304 stainless headers w/CNC flanges and wastegate plumbing
- Garrett G series turbos,
- Tial Wastegates
- Complete oil / water hydraulic lines and fittings
- CNC exhaust discharge adapters to allow use of original exhaust
Suggested options for the TPC 950 system is the Plex tuning boost controller, Dodson clutch, DSC Sport controller for added grip.
The TPC Racing modified Capristo high performance GT2 system features dual path exhaust to be the ultimate in sound and uncompromised performance controlled as an option by the DSC Sport Controller.
The TPC Racing modified Capristo Exhaust systems are engineered and manufactured utilizing advanced 3D Laser-Scanning, CAD Design, Digital prototyping, and CNC-bending/milling at our factory in Germany. Each system is made of high-grade T309 (1.4828) Stainless Steel and hand polished to a mirror finish. After extensive research, this specific alloy was chosen for its sonic resonance properties, low weight, and durability which are close to the properties of Inconel (used in F1).
SPORTS CATS 200 CELL:
The High Performance Sports Catalytic Converters feature 200 cell per square inch substrate fashioned from the highest quality materials currently available designed to improve air flow for your vehicle and increase performance.
The cell count of a catalytic substrate refers to the number of holes per square inch and is a direct indication of the flow capabilities of that substrate. The lower the count of holes the bigger the hole need to be to fill one square inch, a bigger hole subsequently flows more exhaust gasses.
All of this High flow will not help if the substrate is ‘squeezed’ into to small a diameter can or pipe. For this reason, The TPC Racing modified Capristo Sports Cats come packaged in 5.2 inch packages to maximize exhaust gas flow and operation of the valved exhaust system.
