Recent Developments Oct 2007

We have acheived 304bhp/195lbft torque at the flywheel with our 2.0L Duratec engine. It was run on Track'n'Road Rolling Road on 26.10.07, you can view the full kit details, including the graph on our Duratec Taper Throttle 304bhp Kit page.

Engine

The Engine is 2.0L Ford Duratec. Through extensive work with the cylinder head we have found it possible to produce sufficient flow to produce over 270bhp from standard valve sizes, these are already quite large at 35mm (inlet) & 30mm (exhaust). We also found it necessary to develop a new larger intake system to cope with the demands of the head.

The standard crank has been modified with an added keyway groove for strength. We have designed a piston which is lighter than standard. In addition the conrod has redesigned and also made lighter (455g).

To enable us to improve the horsepower of the Duratec above 250bhp, a new design of bigger throttle bodies was produced.

MBE Management & Control
The MBE 970 ECU has been used to control the fuel & ignition. The engine uses 8 injectors to deliver the fuel. 4 in the inlet manifold below the butterflies and 4 in the air horns inside the air filter. The lower injectors are used supply fuel at low RPM and low throttle openings, as the engine speed throttle opening increases the lower injectors are fade out as the upper injectors increase there fuel delivery.

The lower injectors needed for rapped throttle response and slow gas speeds. Where as the upper injectors being further away give the fuel more time to mix with the incoming air help the engine to produce more power.

The ECU controls the wasted spark. The MBE970 not only controls the engine but may other functions as well. It is able to turn the alternator off an on to reduce BHP losses. Launch control which in its latest form has 8 different maps that can been set-up to control the Revs for up to 8 seconds from the start line, the driver can select 1 of 8 launch sequence even on the start line with an adjustable knob before beginning His or her start. The MBE970 system has many other functions available included Radfan control, Electric water pump control, Power shift (or Full throttle shift), Wheels speed less traction control (only suitable for sequential gearboxes), as well as output you configure to suit your own needs.

High specification stainless steel exhaust manifold especially designed for the 2.0L Ford Duratec engine has been used. The low exit exhaust manifold utilises the 4-2-1 system with a 2 3/4" outlet which improves the mid range and top end power.

The Westie was taken to Track'n'Road Rolling Road in December 2006, which showed that with the right combination of intake system, CNC worked cylinder head & our exhaust manifold that this performance level was achievable at a reasonable cost.

The Rolling Road, in Rainham, Essex where the power run and remap was done is a collaboration between Steve Pitcher (Track n Road) and Steve Greenald (Race Engine Calibration). Between them they have over 60 years experience with performance engines. When Steve.P. decided to upgrade his Rolling Road facility 4 years ago he invited Steve.G. to move his 400 BHP Schenck engine Dyno from Ilford where he'd operated since 1984, to share the premises at Rainham. They in fact built 2 Engine Dyno Cells and hope to have Steve P's freshly reconditioned 800 BHP Froude machine running mid 2006.

The Rolling Road is a superbly accurate and repeatable German manufactured TaT CH2 machine, 1 of only 4 made to date. It's 1200 BHP single roller technology combines with a 4000 Nm retarder which caters for serious mapping work as well as inertia only power runs.
