The unique shape of the combustion chambers, improving the resistance against detonation.
High cylinder head clamp load, enabled by a specially designed engine block. This has proven to give a zero failure rate to combustion overpressure, even considering the extreme cylinder pressures.
A unique engine block design, where the cylinder sleeves are used to further stiffen the aluminium block.
A connecting rod design that reduces TDC dwell time and thereby enables higher mean pressures without detonation.
Exhaust manifold and intake plenum trumpets designed to ensure the absence of peak RPM resonance and back pressure.
An efficient ejector pump system reducing the crankcase pressure and aerodynamic losses.
