BMW M5 (V8 version)

PLEASE CALLOR EMAIL FOR MORE DETAILS OF THIS HEAD

The M5 is a fabulous car. That engine and brilliant chassis make it a superb choice for saloon car racing. Ric Wood (CNCHEADS owner) has an enviable reputation for building V8 race engines having built championship winning V8's for nearly 20 years. When he was commisioned to build an M5 race car (including chassis and engine) we gave the engine the full CNCHEADS treatment. This also means we were able to build and verify power outputs on our own Dyno and rolling road.

After extensive development we ended with a head capable of 662BHP at 8200rpm and 464 Ft Llbs of torque at 6400rpm. We then went on to build the full race engine with appropriate exhaust, fueling , ingnition changes and our own camshaft designs. Our engine was within 1% of the predicted power output. The engine is a monster. Massive torque and top end power. The car is a real race winner.

If you would like further details of this head or a full race engine build, please call us.

Cost for this head pair is £2000.00 + vat on. (No exchange). A 'taping' service is also available for this head at an additional cost of £100 which will give the final hand finish to the ports and provide a further 1% flow. This price includes valves.

Note : flow diagrams show flow against specific valve openings at 0.050 inch valve openings at 10" pressure. Therefore actual flow volume increase is measured as the area under the graph (indicated in yellow for inlet and blue for exhaust). Standard valve sizes are used on our heads unless specified as a big valve version. Tests shown here are carried out on a flow bench on a bare head without filters. Therefore the difference between a standard engine with standard inlet ducting and filters will be larger than shown here.
