Audi S3 8V - JB4

Audi S3 8V - JB4

This is the first MQB chassis car we've had on the dyno fitted with the newly released JB4. The Audi S3 comes standard with 300 bhp and with the JB1 we would see anywhere between 350-360 bhp so we were expecting somewhere around that region.

As you can see from the graph below, the JB4 combined with 99 ron fuel made much more than both the customer and we were expecting. After coming from an almost 400 bhp M135i, the power upgrade was certainly needed.

The graph shows the cars stock power, the power on map 1 and the power on map 2.

Power gained: 77 bhp

Torque gained: 50 ftlb
