Ducati V8 Project

By

Do you remember Dieter Hartmann-Wirthwein? He built that amazing little 125cc inline 4 Monkey bike. I guess Dieter isn't the kind of guy who sits around all satisfied with himself, he figured he could do something even better so he's busy working on another project, an 868cc Ducati V8, he calls it Ducati-Elenore. This is still very much a work in progress, you can see from … [Read more...]

Supercharged Honda 50 Racing

By

Anders Elsberg of Denmark has a long history of tuning and racing small displacement engines and the Honda 50 is one of his favorites. Though many tuners and racers of the little Honda will simply increase displacement and compression and add performance cams, Anders didn't want the tradeoffs required, a higher and narrower useful RPM range being the primary problem.

Paul Carberry, down in … [Read more...]

Hartley Enterprises H2 Busa engine

By

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. … [Read more...]
