When it comes to improving horsepower and rpm, airflow has a lot to do with it, and it seems the job is one that’s never finished.
Right away, engine builders knew it was special.
The complexity of cylinder head set up and flow bench testing comes in the form of math, aerodynamics, thermodynamics, and the physics it takes to design the correct port and manifold design for a particular engine combination. These processes take years to master.
Cylinder heads, as manufactured, are usually suboptimal due to design and manufacturing constraints. Porting the heads provides the finely detailed attention required to bring the engine to the highest level of efficiency.
In general, the most critical areas when porting a cylinder head are those which pass the most air at the highest speed and for the longest duration.
Katech Inc. has developed new proprietary CNC porting technology to increase horsepower on Gen 5 LT1 and LT4 engines found in C7 Corvettes and Gen 6 Camaros. Katech’s CNC porting technology increases the heads’ airflow velocity and capacity.
