How to Tune a Volvo S80

Add a dash of performance to your Volvo sedan with a few bolt-on modifications.

Successor to the popular 960 series, the S80 was an all new model for Volvo, first arriving at dealerships in 1998. Available exclusively in sedan form, the S80 includes a high level of standard equipment, and luxurious interior designed to compete with upscale sedans, such as those offered by front runners BMW and Mercedes-Benz. Volvo offered the S80 with a myriad of engine options, including a 2.4-liter straight-five producing 168 horsepower, a force fed twin-turbo 6-cylinder model that developed a peak of 268 horsepower and even a V-8 on newer editions. Tuners quickly learned these engines could be modified for greater performance with a series of basic upgrades.

Things You'll Need

• High-flow intake
• Big brake upgrade kit
• Sports exhaust system
• Strut bars
• ECU tuning

Instructions

1. Install a drop-in replacement filter into the factory air filter to increase flow to the engine, while maintaining a completely stock appearance. This upgrade will yield even larger gains on S80 models equipped with a turbocharger, as it allows for quicker spool-up times.

2. Replace the restrictive factory exhaust with an aftermarket unit designed to relieve back-pressure, and allow spent gases to escape faster. On turbo models it is recommended to replace the entire exhaust system, from the turbine housing to the muffler, to maximize gains

3. Reprogram the engine control unit, not only to enhance the effectiveness of all modifications, but also to update the conservative timing and fuel maps set at the factory.

4. Add a big brake kit, consisting of larger diameter rotors and high-performance pads, to minimize the instances of brake fade, and significantly enhance stopping power.

5. Install a set of strut tower brace bars to improve the vehicle's handling and allow for more direct steering inputs.

Tips & Warnings

• Use a vehicle dynamometer to gain a detailed analysis of engine output.

• Modifying your S80 can void your warranty and cause damage to critical components. If in doubt, consult your Volvo dealer or the manufacturer directly.
