Front End of Car

25KB JPEG

Front hub and brake assembly showing the large ventilated and drilled discs with Dynalite 4 pot calipers (it is hoped that the use of nearly bald Escort van tyres will not compromise this braking system...). Attached to the end of the track rod is a speed sensor that will be used for data logging and traction control.

Engine is currently an SD1 unit fitted with the pre-SD1 rocker covers. The Vitesse type fuel injection system is retained with modifications to improve performance and allow fitment under the Westfield's bonnet.

A Laminova oil/water cooler seen here centre left takes care of oil cooling. This has the advantage of warming the oil quickly too. The green wires on the right of the engine bay will allow the management computer to receive information on the before and after temperatures of water and air passing through the radiator.

In the centre of this picture, just below the home made idler pulley, can be seen the crank sensor. This will pickup from a bicycle chain wheel which has 1 tooth removed. The idler pulley is needed to stop the belt from fouling on an engine bay cross-brace.

TVR Power supplied remote oil-filter take-off, required on all SEiGHTs to clear the steering column, is fitted with a thermocouple to monitor oil temperature when the oil returns from the filter/cooler. There is another thermocouple in the sump plug to monitor temperature as the oil returns from the engine. This steering column is hollow to save weight.

Distributor is fitted with aluminium blanking plate over the internals. Ignition will be via separate coil packs for each cylinder under full electronic control. The distributor is used to provide a drive for the oil pump and to provide a single pulse every 2 engine revolutions to allow the management system to determine cylinder phasing. This pulse is provided by the standard Lucas 35DE8 internals with 7 of the 8 ferrite rods removed.

Attached to the rear of the nearside cylinder head is a coil pack. There will be another on the offside.
