Introduction

Based around the 660kW Transient AC Dyno, Prodrive’s new powertrain facility at Banbury will help accelerate the development of a new generation of alternative-fuel and hybrid propulsion units.

SCP’s CAHU supplies the engine with temperature, humidity and transient pressure-controlled induction air as required – with low temperature mode, enabling the test cell to replicate a wide range of race track running conditions. The test cell equipment provides the ability to simulate near exact running conditions and replicate in vehicle transient operating cycles. Having a transient dyno is perfectly suited to powertrain calibration, durability testing and performance development.

The engine and powertrain elements are conditioned by the high performance ventilation system which is variable speed and temperature conditioned to allow consistent day to day temperature settings. Multiple function oil, coolant and fuel delivery and conditioning systems further enhance the precise nature of the testing that can be delivered from the test cell. Twin exhaust extract system with integrated silencing and back pressure control complete the system.
