ECOBOOST DEVELOPMENTS
�ur��i�it�to������o��r���or�t���tra����rofi�����atur��in�t����ugu�t������t����r� issue, revealed that the Ferrari race engine specialist had also been doing some interesting development with the Ford 1.0-litre 3-cylinder Ecoboost engine, pushing the design of the award-winning power unit to another level.
David Wedge of DTM Power recalls ��ur first look at this engine, still mechanically standard, but with a user programmable ECU, enabled us to get the power up from the standard published 120 hp at 6500 rpm with 133 lb. ft. of torque at 2500 rpm, to a very satisfactory 150 hp at 6500 rpm with 157 lb. ft. of torque at 2500 rpm.
‘ Of course that was just the baseline run, but we can supply an ECU and wiring to enable those power and torque levels to be available from the standard engine, without any need to remove the engine from the car.
‘ We then moved on to the real development task, with an engine re-build and some new upgrade parts, comprising forged pistons, steel conrods, re�ised cam profile, and the key element, a significantly increased cylinder head air�ow capacity� �hat is the point where the standard fuel system runs out of capacity to deliver enough fuel, so we ran some ��I injectors with 30 per cent increased �ow� �esults were an impressi�e 200 hp at 6500 rpm and a peak torque of 195 lb. ft., still at 2500 rpm.
‘ Next stage was to remove the fuel �ow restriction and that requires running port in�ection phased with ��I� �he one problem with ��I is the tight limit to the time available to inject the fuel; only possible when both valves are shut. But with port injection, available at any time during the engine cycle, the problem was solved.
‘ A bigger turbo was now required to keep up with the cylinder head �ow rate, and with no fuelling limits the stunning result was 302 hp at 6500 rpm, still with a remarkably �at torque cur�e peaking at 2500 rpm. An all-new intake manifold plenum with port injector mounts and a bigger throttle body were the final upgrades to enable this performance level. At the bottom end the fuelling requirement is not much different to the standard engine, so that low-end low throttle driveability is maintained’.
Although DTM Power has now moved on from this project, the development engine is currently offered for sale. Contact DTM Power on 07768 717 702 www. dtmpower. com
