We've been enamored with the idea of stuffing a Suzuki Hayabusa-derived V8 engine into an appropriately light and sporty four-wheeled conveyance since we first learned of such a powerplant's existence last Spring. The task of creating a 'Zuki-powered sled is set to become significantly easier now that Hartley Engineering has managed to rework the 'Busa block a bit. An entirely new crankcase has been designed and hewn from a huge chunk of 6061 T6 aluminum. It may not be a V8, but this new inline-four engine, known as the H2, is a diminutive powerhouse that can bolt right up to a standard automotive transmission. Why is this a big deal? Motorcycle gearboxes generally don't have a dedicated reverse gear and usually output their high-revving power via a chain. Now, the prospect of a 140-pound engine with over 200 horses powering something along the lines of a Super 7 has us salivating once again. Those with equally imaginative minds can now begin plotting their next projects, as the H2 is expected to be ready for purchase in early '09.

If four's good, then eight must be better - that's the idea behind this jewel-like V8 engine built by Hartley Enterprises from two Suzuki Hayabusa four-cylinder powerplants.

The 75-degree V8 displaces 2.8 liters, weighs only 200 lb and puts out 400 hp at a window-rattling 10,000 rpm. Torque peaks at respectable 245 ft-lbs (at 7500 rpm!), although dyno runs for a 2.6 liter version show a fairly flat curve. Aside from boring out the 'busa block from 81mm to 83mm, none of the wide variety of performance enhancements available for the bike version have been applied to the HE V8, so it's safe to say we're nowhere near the performance limits of the design.

Hartley's diminutive V8 is produced to order, with the 2.8 liter version priced under $30,000, depending on options. Check out the Hartley Enterprises website for more details, including video of a dyno run with the engine installed in a Caterham 7.

Thanks for the tip, Matt!
