How to Increase HP on a 996

The 996 is the model number for all Porsches built between 1998 and 2005. Increasing the horse power (HP) on this German sports car can be accomplished in a number of ways. The Porsche 996 came with two engine options the 3.4 litre H6 and the 3.6 litre H6. It is a rear engine car with rear or all wheel drive. The fastest model 996 (the GT2) came with 489 horse power.

  1. 1

    Replace the intake, headers and exhaust. The three aforementioned components constitute the air flow system in the vehicle. Air flow (both in and out,) more specifically unrestricted air flow, are at the heart of engine performance. There are many aftermarket company's that specialise in Porsche performance parts and the first thing a driver should do to increase power is replace the intake, headers and exhaust with performance ones. This will help the engine receive more air in and help it expel the air more efficiently. The result is increased horsepower.

  2. 2

    Adjust the computer or ECM (Engine Control Unit/Module, sometimes called ECU) on the 996. The on board computer controls a number of different functions for the car. The default settings are set-up for the daily drive and not tuned for maximum performance (which will decrease fuel efficiency.) Purchase a 996 ECM control unit. This will plug into the 996's ECM and the driver can tune the car to the optimal settings for maximum horse power.

  3. 3

    Add a turbo. The base model 996s do not come with a turbocharger. Obviously the 911 Turbo does. Still the base 996s can easily accommodate a turbo. A turbocharger is a form of a supercharger. It increases the amount of air pressure entering the engine; which results in more power. Turbos can be expensive but they can dramatically increase the amount of horse power the car generates.
