Hi

I have a 2013 S60 T5. I would have loved to have gotten the T6 but none were available in my area. Is there anything I can buy/do to increase the torque and HP without damaging the car? I don't know anything about mechanics or engineering so I am here asking you experts.

Looking forward to hearing from you guys.

Thanks for the help.

 

A T6 with the FOMOco/Volvo/landrover inline 6 can easily have 325 HP and 354 ft lbs of torque. You would have to spend a whole lot of money and make your current engine less reliable to get that out of a Volvo 5 cylinder.

 

Adding HP to a turbo engine is all about air flow. First is boost - turbo engines use a waste gate to limit the amount of boost pressure being sent to the intake. You can buy an "ECU tune" that changes the ECU computer's program to allow more boost. Second is exhaust. to help get more air into the engine, you want to help get the air out of the engine. This can be done via a larger down pipe (the first section of the exhaust between the turbo and the catalytic converter, or a free flow exhaust system (the part after the cat). Next is intake air temperature. As the turbo pressurizes the intake air, it heats it up. warm intake air can lead to pre-detonation and a lower density so a bigger intercooler helps manage this. With all this extra air, you need extra fuel, so increasing the size of the injector flow is needed. Finally, you need to get air in and past the air filter so a free flow intake will help. To optimize reliability all this has to be done in balance, which is why tuner shops recommend "stage" packaging. A simple ECU tune with a mild bump in boost providing 25-50 extra HP can be done stand alone with the only requirement being 93 octane gas. Anything beyond that and you'd want an engineered package. Also note as you start getting over 300 HP, you'd need to start thinking about the drivetrain. If your car's automatic was selected for a 200 HP engine, it may not be capable of handling 350 reliably (manual transmissions have a big advantage here as they are generally stouter).
