LSA ZL1 Eaton 1.9 Super Charger Snout porting

weapon X motorsports


Snout porting refers to the process of modifying the intake of the super charger to improve the quality and quantity of the air flow. The stock snout as manufactured, is suboptimal due to design and manufacturing constraints. Porting provides the finely detailed attention required to bring the engine to the highest level of efficiency. More than any other single factor, the porting process is responsible for the high power output of modern engines.
This process is applied to optimize its power output, for daily use or to alter its power output characteristics to suit an aggressive pulley combo.  By spinning the super charger lobes faster, more air is pulled through the snout and the smoother and wider the intake area, the less restriction and less boost will be created allowing more horse power through the drive train.
Daily human experience with air gives the impression that air is light and nearly non-existent as we move slowly through it. However, an engine running at high speed experiences a totally different substance. In that context, air can be thought of as thick, sticky, elastic, gooey and heavy. Pumping it is a major problem for engines running at speed so head porting helps to alleviate this.
