The graph below shows the power output from a car with the modifications listed above
The graph shows power at the wheels (blue), power lost through the transmission and tyres (green) and calculated power at the flywheel. This car made 264bhp @ only 14psi of boost, the increase in performance comes from the modifications to the engine. More power could be liberated with a higher flow intercooler and more boost pressure. The Stage 2 chip optimises fuelling and ignition timing to take best advantage of the modifications.
