Klauss Hoffmann - Stage-2 - Chipset. This chipset improves the performance of the 964 Carrera 911 in many ways. Most importantly it improves low, midrange and driveability. The great benefit of all Klauss Hoffmann chips is that they are designed to remain flexible to work with other performance enhancements, such as exhaust and intake improvements.

FILTER STAGE-2 - Performance replacement element

FILTER STAGE-3 - Performance cone filter

EXHAUST - STAGE-2 - The earlier 911 models were fitted with a design of exhaust which was developed to produce power. The nice side effect was that the 911 sounded amazing! Prior to the 911SC Porsche had to re-design the exhaust system so a single catalytic converter could be installed in californian models. This restricted the system and so reduced performance. Our polished stainless steel exhaust system replaces every part of the exhaust, including the heat exchangers to a design similar to the early cars such as the original RS 911. The system has been designed though to have enlarged pipes tuned to release optimum power from the SC and carrera models along with a revised tailpipe design to keep within the style of the later cars.

9XX BOOST IMPROVER - Device to reduce lag and improve top end performance of the 911 turbo models. Makes simple adjustment to boost levels.

EXHAUST - STAGE-2 Turbo - Like the 3.0 SC and 3.2 Carrera exhausts, the 911 Turbo exhaust was designed to allow Porsche to install a catalytic converter in the californian market. the 9XX 911 Turbo exhaust is designed for pure performance as well as other drawbacks to the 911 turbo system. Available with single or dual tailpipes, this system allows quicker turbo spool up as well as reduced losses caused by backpressure in the standard system. This system is similar in design to that used by RUF in their air cooled tuned 911 turbo models. Unfortunately this item is often subject to a manufacturing pre order time.

DUAL PORT WASTEGATE - 9XX STAGE-3 - Replaces standard wastegate with new version designed with dual port control head. The stage 3 version also includes cooling fins and a 46mm port for control of boost even with uprated turbochargers up to 850 BHP.

DUMP VALVE -9XX STAGE-2 The addition of a dump valve to a 911 turbo does not increase power on a dyno run, but allows the turbo to continue spooling on fast gear changes. It also protects the turbo against compressor stall during decelloration and during gear changes.

TURBO - STAGE-3 9XX - Our stage 3 turbo incorporates a hybrid design offering improved design over the standard item. Our turbo goes much further than others to incorporate many other benefits to performance and reliability such as a 360 degree bearing and improved compressor and exhaust turbine design.

TURBO - STAGE-4 9XX - Our stage 4 turbo incorporates a hybrid design and many of the other benefits of the Stage-3 turbo, however it also includes a ball bearing design which allows it to spool up much more rapidly, reduces drag (and lag) and is of a much more durable design due to the use of ceramic ball bearings. The turbo also uses a lower quantity of oil due to this design, therefore not sapping away as much oil flow from the rest of the oil circuit, therefore increasing oil pressure to the rest of the engine in extreme scenarios.

FUEL PUMP - STAGE-3 Motorsport - Our motorsport fuel pump has been tested on cars providing up to 650 lbs of torque. Important in particular with highly modified cars as the standard fuel pumps (when new) only have a safety margin of some 10%. When modifying your 911 your standard fuel pump may run out of capacity causing a lean condition.

DYNO TUNING - Charged by the hour we are able to setup your car on a rolling road dyno tester. This is charged by the hour and logs not only BHP and Torque but also boost pressure, air fuel ratio and much more. For a perfectly tuned car this is the only real option to set it up.

WIDEBAND AFR DISPLAY- Air fuel ratio guage, with datalogging ability, pod mounted

Computerised 4 wheel laser alignment to standard or performance settings

FRONT WISHBONE REBUILD - 9XX Front wishbones remanufactured and improved to the special 9XX specifications racing version with new ball joint and composite bushes. (requires 4 wheel alignment to setup) priced per pair.

COMPOSITE SUSPENSION BUSHES - 9XX Bushes are available to replace almost any bush within the suspension previously made from rubber. These items will improve controll and driver feedback. Price for these are on application dependent on which bushes you desire to be uprated.

STRUT BRACES - 9XX strut braces improve the rigidity of the 911 frame allowing more precise handling characteristics with reduced flex and improved driver feedback through the steering and suspension

ANTI ROLL BARS - STAGE-2 - 30mm front and 19mm rear (adjustable) anti roll bars, with rubber bushes. Alignment recommended,

FRONT SUSPENSION - STAGE-2 - 9XX Koni custom built adjustable shock absorbers for cars without Koni MO30 height adjustable front suspension. Alignment required. Priced per pair.

FRONT SUSPENSION - STAGE-3 - 9XX Koni custom built adjustable shock absorbers. Both adjustable for shock absorbing and for front ride height. Includes fitting springs to suit customers requirements. Alignment required. Priced per pair.

REAR SUSPENSION - STAGE-2 - 9XX Koni adjustable shock absorbers. Alignment recommended. Priced per pair.
