The PowerHaus Bolt-On 968 Power Package is a comprehensive package for all 1992 and later 968s. While not including all possible improvements, it is composed of those items which we feel deliver the best bang-for-your-buck.
1. PowerHaus Engine Management Chip. Our chips are custom programmed by AutoThority, the best programmers in the business. The EPROM chip is designed to work specifically with our exhaust package, and can be custom-tailored for your specific vehicle.
2. PowerHaus Stainless Steel Exhaust System: Our lightweight "cat back" system is a bolt-in replacement for the heavy factory muffler. It is hand made from 321 alloy stainless steel, fully polished, and gives the car a deep, sporty sound. It is a direct bolt-in replacements for the OEM muffler, and use all OEM mounting hardware. A stainless catalytic test pipe is available for racing vehicles only -- inquire for details.
3. PowerHaus Air Intake System: A lightweight and very free-flowing replacement for the factory air box. Works well alone, or with our EPROM and free-flowing muffler. Includes air intake pipe, K&N filter, and all hardware.
| Observed horsepower gains over Stock, tested on DynoJet 248E chassis dynamometer: | |
| EPROM Computer Chip | 16 |
| Stainless or Carbon Fiber Muffler | 15 |
| Air Intake System | 5 |
| TOTAL PACKAGE: | 36 hp |
Tested on a 1992 968 Tiptronic Cabriolet |

This is approximately a 45 hp gain if measured at the flywheel on an engine dyno. There are further gains to be had in aggressive cylinder head preparation, but the returns would be slight when weighed against the costs.
If you have any other questions regarding these, or other upgrades, for your Porsche, please feel free to call us. We have a great deal of experience with the 944-968 series, and are happy to share this with you.

Porsche produced a very small number of 968 Turbos for the non-US market: the limited edition 968 Turbo S. This vehicle sold for approximately 175,000 DM, and only had a standard eight valve cylinder head. Power was rated at 305 hp and 369 lb-ft of torque at 1.0 bar tested on an engine dyno.
PowerHaus consistently builds 944 Turbos that produce 320+ hp at the rear wheels from the 2.5L 8V engine. The output of the 3.0L 16V Turbo engine is guaranteed to be in excess of 400 hp, with equivalent torque. These are the same results Porsche achieves with the 1996 Twin Turbo.
This combination of horsepower and torque, coupled with the factory 6 speed gearbox, will produce a car with extraordinary ability. At the same time, there will be no loss of driveability or reliability from the turbocharger. The vehicle's near-perfect weight distribution will not be disturbed, so the car will continue to handle like the supercar it was intended to be.
