This is a dedicated motorsport engine, and although in general form it is not built for a specific application, variations can be built to suit the regulations of several motorsport disciplines.

The cylinder head is fitted with Q450V profile camshafts with solid cam followers and uprated springs. The inlet and exhaust ports are also reworked and enlarged and our direct to head throttle bodies are fitted to improve gas flow.

To accomodate the higher lift cams, forged pistons are fitted with deeper valve pockets but these also give a higher compression ratio, usually 12:1. Heavy duty con rod bolts are fitted to allow the safe use of higher rpm with rev limits typically set at 8000 rpm. As an additional option, for race applications, a lightweight steel flywheel can also be fitted to make the engine more free revving.

Typically these engines use a baffled wet sump but dry sump systems are also available.

Ignition and fuelling is controlled by a DTAfast ECU which is supplied with a dedicated engine bay wiring loom and all of the relevant sensors.

The complete engine is then run in, mapped and power tested on our dyno. Typically these engines give 175 ftlb of torque at about 5500 rpm with peak power of 240+bhp at 7750 rpm.
