Air Intake And Exhaust System
Boost system
The petrol engines from the VEA family, depending on the engine variant, have a boost system that consists of only a turbo (B4204T9/T10/T11/T12/T15) or combined turbo and compressor (B4204T9, T10). Engine B4204T9 and T10 have a maximum output of 306 hp and 400 Nm of torque at 2100 r/min. In order to get the relatively small engine to deliver such a high level of torque from really low revs, a belt driven compressor driven by crankshaft is used. The compressor is used at low revs whilst the turbocharger is used at high revs. The system produces a high level of torque directly from low revs.
