Hartley Enterprises makes the excellent H1 Hayabusa V8 engine. That’s the one used by Dennis Palatov in his Ariel Atom. Drawing on their experience creating the crankcase for that engine, they’ve designed a 6061-T6 billet crankcase for the Hayabusa top end that turns the inline 4 into an engine that will bolt right up to an automotive transmission like the Ford Sierra Type 9.
A common engineering problem when trying to create a motorcycle engine powered car is what to do for a gearbox since motorcycle boxes, among other issues, tend not to have reverse gears, except for some trikes and big touring rigs and don’t hook up easily to automotive drivelines. The H2 Busa takes care of that issue quite nicely. Quaife makes various gearboxes and differentials for adapting motorcycle engines to automotive applications but the Hartley H2 makes the whole process easier and your choice of transmissions wider.
The whole engine will weigh about 140 pounds, put out 175 to 250 horsepower with the potential for a lot more when mounting a turbo. It will be offered as a kit or in completed form with availability in the first quarter of 2009. No prices are specified yet. Think of the possibilities! Nice.
