Description

In order to achieve higher speeds, one should reach for the racing shaft. The extended intake timing results in a much freer engine revs. This measure is especially noticeable with high-revving cylinders.

The quality of the crankshafts is very good and so they resist even the highest revs. Especially for engines with a larger displacement, they are an optimal supplement to extend the usable speed range.

These engines turn out freely, which leads to a significant increase in top speed.

The extended stroke is also a very good instrument for changing the basic design of an engine. In doing so, the engine can be trimmed either in the direction of torque or speed via cylinder head and base gaskets of different thicknesses.
