Welcome to Superpower Unlimited

Based in Scotland we offer a wide variety of Performance American V8's and Jaguar V12 Engines and have built up a reputation for value and reliability within a diverse range of Motorsports ranging from Fast Road Cars to Nitro burning Dragsters!
 
Having worked as a Jaguar mechanic in the 70's & honed my skills in the States back in the early 80's I soon realised the saying 'There ain't no substitute for cubic inches' to be true! The Jaguar V12 can be supplied from 5.3 litres up to 8 plus litres. American Chevy's and Ford's, form 289cu.in. up to 760 cu.in.12.5 litres!
All primary parts USA manufactured with assembly & building carried out at our workshops to your specification. For customers who require Horsepower & Torque numbers we offer engine Dyno facilities up to 2000HP.
 
For road car and club racing enthusiasts we have created the New Boss 302cu.in engine with a displacement range up to 360 cu.in, 5.9ltr using the New Boss Motorsport 302 Block as the foundation. These engines are extremely adaptable and built in the true spirit of what Ford unleashed to the market in the early 70’s. All are custom built to suit many types of road or racing applications.
