For Aston Martin Racing GT4 chassis the services we offer include:

4.3L engine rebuild

Our understanding of wear rates and deterioration factors are insights that simply aren’t available to teams who haven’t been through the same experience curve. To maintain optimum power output and durability a service interval of 10,000 race kilometres is recommended. During the service we pay particular attention to the parts most vulnerable to wear. In addition, should you encounter a problem or simply want a refresh after an accident, we can offer:

  • Rapid turn-around of your original engine
  • An exchange unit while your engine is undergoing repairs

4.3L conversion to 4.7L GT4 specification @ 500BHP

A 4.3 litre to 4.7 litre engine conversion for the V8 Vantage which results in a true racing engine. Suitable for Aston Martin Owners Club (AMOC), GT4 class racing, Britcar and VLN.

We re-manufacture the original 4.3 litre engine, using original equipment parts and built to standards which are proven to win race championships – yet this is a cost effective alternative to other Aston Martin racing support providers. The result is a hand crafted, high performance racing engine.

Instead of simply selling a stock production part, Bamford Rose converts a production 4.3 litre engine into VLN series race engines ranging from 450 to 475 BHP. All rotating and reciprocal parts are balanced to Formula 1 standards, offering increased durability and throttle response. The culmination is a fully blue printed and optimised racing engine.

Exhaust Manifold and catalyst performance upgrade

Bamford Rose was the first to the market for exhaust Manifold and Catalyst upgrade. The exhaust system can be fitted to both 4.3L and 4.7L GT4 cars and together with an ECU reflash provides an instant 45BHP peak power increase, and 50Nm Torque increase across the rev range. Significantly lesser outfits in the ‘MotorSport Valley’ have tried their best to imitate this product but fail in terms of component quality and intellect required to properly re-map the ECU to achieve the ultimate power output. Meaning it has become repeatedly evident that whilst Bamford Rose has competitors, in reality Bamford Rose has no competition in this segment of the marketplace.
