New! Datalogger See also: Venom Racing Chaos Welcome to Superpower Unlimited. We are based in Scotland but offer a truly American flavour for 'Big Inch Engines' Scotland maybe short of drag strips but there is miles of coastal water to have some fun on! I hope you enjoy the the pics as much as I did. 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 a mere 320 cu.in or 5.25 litres. Try 502 cu.in. 8.2 litre as stock up to 706 cu.in. 11.5 litre!! All primary parts USA manufactured. Assembly & building carried out at our workshops to your specification. We specilise in Big Block Chevy 454 to 706 cu.in & Ford 460 to 690cu.in for street / strip / marine applications. Nitrous Oxide Injection, Super/Turbocharging. Complete engines from 450hp to 1000hp plus!! If what you see grabs your attention, couple all those 'cubic inches' with a proffesionally prepared 6 to14-71 Blower, Dual turbocharger system, Nitrous Oxide system or a combination and you will soon realise 0-60 times you could only dream about!! Like 2 seconds in a correctly set up street vehicle??
