TRACK ROCKET 140

As the name suggests this is a track engine specification. Ideally suited to the Club racer, sprinter, hill-climb, Track-day or even wild road car! It’s been developed to give the widest spread of power possible, in our dyno testing we take this down to as low as 3200 rpm at wide open throttle all the way up to 8000 rpm, just perfect for maximum acceleration from those super tight hairpins! A truly cost effective price for a powerful package. The ideal basis for the Mini7 club’s Libre class. BHP (depending on 1330 or 1380) ranges from 132-138 BHP @7500 RPM 110 ft/lbs @5000 RPM.
