In the short term, all the turning work can be carried out. This is important when it comes to the adjustment of control times, compression and crushing edges, i. Cylinder heads and cylinders must be turned off. All milling operations can also be carried out.
In the machining of the cylinders, the better or more streamlined design of the transfer channels, the cross sections in general and the size of the channel cross sections at the cylinder foot outlet (cylinder base gasket). The outlet cross-section is also important.
Individually, the Boost Port channel is called a support channel. This is the so-called 3rd overcurrent channel opposite the outlet. Here, too, the better, more flow-favorable design of the channel, of the cross-section in general, and the size of the channel cross-section at the cylinder-foot outlet (cylinder base gasket) are obtained.
Moreover, the design of the outlet is of great importance. A broadening (measured in the gauge of the tendon) up to 70% of the bore is quite common in the racing sport, whereby one should not go over 65% bsi 68% with everyday engines. A widening can lead to an increase in performance over the entire speed range. If the outlet is extended to the top, the nominal speed and the power increase - the force also decreases at low speeds = torque.
