Back to Models

The 4.2 V8 TDi engine utilises a Garrett VNT turbo, intercooler and Common Rail injection system with Bosch EDC16 ECU controller. Running pressures up to 1600 bar standard the engine provides very solid linear performance and an exceptionally quiet combustion. Once remapped the power increase is all through the rev range with a huge boost to mid range torque and all round drivability. We regularly see good fuel economy gains on these engines and further noise reduction from the engine. We develop all of our software on the rolling road to ensure accuracy in terms of both power delivery and also to ensure fuelling, boost pressures and exhaust gas temperatures are all within tolerance. Our aim is for maximum power whilst maintaining optimum reliability.
