Hartech Oversized Engine Power Hartech Oversized Engine Torque Hartech Oversized Engine In-gear

A Hartech oversized engine will provide improvements in both mid-range and top end BHP and torque and therefore improves acceleration, driveability and all- round performance far more impressively than most conventional tuning can achieve – and as a bonus – without over straining the engine and at a very modest cost if you are considering or need an engine rebuild anyway.
