3.4 to 3.9 Engine Conversion

The graphs below compares a std 3.4 engine with our 3.9 conversion and has been adjusted to compare with the owner’s manual results ;

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.
