Kawasaki ZX11 engine in sports racer similar to a Radical, lost 2 engines in one weekend both times touching 2 G's in a fast cambered corner that goes through a dip, fitted an Accusump and the engine wasn't touched for the next 2 years other than basics including running 4 meetings at the same track/same corner - that corner is famous in Oz for producing high G's, well was, sadly the track Oran park one of Oz's best, closed last year.
Same old story, housing devlopment - see old track at top of picture ..
Too many people over rev the crap out of the engine through mismanagement of downshifts and they go bang - don't use gears for brakes it's that simple.
I can't see how a dry sump can't be up to the job other than a limited flow system in the first place which sounds borderline bizzare - a dry sumped engine can run upside down if you want with the appropriate scavenging.
I wonder how many people who mention short 'Busa life started with a used engine in the first instance? I also wonder how many of them have shock absorption in their drivelines?
