New VAG models

Golf IV and Audi A3 Turbos

GTi Engineering Phase One: "Re-boost" conversion giving an extra 30bhp
This comprises modest changes to the engine management system with adjustment of the boost control and represents the greatest power increase for the least financial outlay.

GTi Engineering Phase Two: "Re-boost" conversion giving an extra 70 bhp
This conversion is a little more tricky requiring radical changes to the electronic control software. The turbo boost is adjusted by means of mechanical changes to the wastegate and control pipework. With this conversion, the output of your turbo is taken to the limit of efficient maximum airflow possible without fitting a larger turbocharger.

GTi Engineering Phase Three: Much more than a "Re-Boost" for proper power.
Cylinder head modifications, larger turbo, electronic changes and an extra 110 bhp!
This conversion is not for the faint of heart. The cylinder head and manifolds are gas-flowed and the combustion chambers are carefully shaped to prevent any likelihood of detonation. The head is lightly skimmed and the gasket seal strengthened. A larger turbo with a higher air-mass flow is fitted and the engine management system is totally re-mapped to accommodate the changes.

Audi A4, A5, A6 and A8

BBR Interceptor 2000 is used as a basis for tuning these vehicles. Whether the engine has 1, 4 or 12 cylinders, this device can be fitted and the makers software enhanced to improve performance.

The first car in this range to have the Inteceptor fitted was the A8.  A new vehicle arrived, in its wax, bound for the Middle East, with the order to somehow improve the power output.  The standard engine management system on these vehicles is very complex and at first the task looked quite daunting.  However, after a long cool look, it was decided to attempt to fit our Interceptor 2000.  The initial analysis of the electronics on the new vehicle took about 50 hours and the software in the Interceptor 2000 another 50 hours!  Our electronics division, launched into the ECU's printed circuit board to perform the requisite delicate surgery, fitting the inerceptor and HEY PRESTO - the job was done! The vehicle was then tested on the rolling road to perfect the fuel and ignition maps, a very useful extra 25 horsepower being found.

From there, applying the technology to the lesser models, proved to be a relative picnic! We are now able to fit the Interceptor 2000 to the other Audi models - and they all receive power increases by the same proportion.


Other conversion work available follows along more conventional lines.  We have a range of camshafts available, cylinder head modifications, exhaust systems etc, and for the serious power freaks, we are able to carry out major power conversions right up to racing specifications.
