The engine below is a supercharged Ford Duratec built by JEMS. It’s the first time JEMS have put their extensive engine building knowledge to extracting this type of power from the Duratec.
The engine sits in a Mk2 Escort circuit racing car which runs with one-off Subaru running gear. JEMS have helped to develop for the last four years. When it was decided to take another step up in the cars performance many engine options were considered. The final decision was to develop the cars existing Duratec engine.
JEMS stripped and performed an analysis to see how they could improve power. To have generated such a large amount of power at the first attempt is a great achievement.
The car drives like a very big naturally aspirated engine. It is very drivable and responsive with no power surge like you get with a turbo engine. It applies power with a very linear delivery and you can hold rpm in a corner to settle the car.
