Klauss Hoffmann - Stage-2 - Chipset. This chipset improves the performance of the 993 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 993 with the correct high performance rear silencers can produce the most amazing sound while also gaining small gains in performance. The 9XX silencers are the product of years of development while monitoring the other alternatives such as the RSR silencers. The 9XX items gain on knowledge gained from ongoing development to produce the best available items.

9XX can also produce cat-bypass sections for the 993 models, call for details.

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

INTERCOOLER STAGE 3- A much larger intercooler designed to improve on boost performance even without increasing the boost, but also allows the use of higher boost without issues.

WATER INJECTION - Still under development - our water injection system has been installed on several 911 turbo's and has allowed the use of much higher boost levels. This system in not for the feint hearted.

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 often refered to as the K27 or as a 964 hybrid. Our turbo goes much further than that 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

WIDEBAND AFR DISPLAY - Facia mounted near radio, shows air fuel ratio, boost and vacuum, datalogging of air fuel ratio.

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,
