Porsche 911 carburettor repair and rolling road tune

Another lovely example sent our way by Paragon Porsche. This 2.4 litre 911 had a crack in on of the carburettor bodies around a mixture screw. We machined a sleeve to fit around it and pressed it over ensure the crack does not getting any worse. The carburettors were then balanced and setup on the rolling road.

Rover P6 2000 on the rollers

Martin Blum brought his beautifully presented P6 in for a tune today. The 2000cc engine has been fitted with the larger 2″ SU carburettors from the 2.2 and needed setting up. Re-profiling of the needles found an additional 15bhp at the wheels.
