QED COMPETITION SPECIAL

This is our general purpose club motorsport engine. Variations can be built by request to conform to particular racing regulations.A base unit is stripped, inspected and rebuilt. Engine internals are refreshed or replaced as necessary with modifications made to strengthen the bottom end, most notably including fitting forged pistons and strengthened con rod bolts.
A DTA engine management system is fitted to control a twin coil for wasted spark, distributorless ignition as well as fuel injection through a set of our 45mm bore, direct to head throttle bodies. The DTA system uses a 3D mapping strategy, making it sensitive to engine load as well as speed. The ECU also makes adjustments for transient fuelling (under acceleration) and compensates for changes in air and water temperature. As an option the system can also compensate for changes in altitude by measuring barometric pressure.
The cylinder head is ported and fitted with our Q420 mechanical profile camshafts. These require uprated valve springs and are run against solid steel cam followers. To further assist gas flow QED Hi-Flow wasted stem valves are also fitted.
The completed engine is run in on our dynamometer and checked over. It is then fully mapped and power tested (a graph showing power figures is supplied with the engine - see below for a typical example).
