Getting Better Cylinder Head Airflow

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.

All About Those Valves

We recently sat down with Ryan Hamilton and Phil Data of SBI, as well as D&J Precision Machine owner Drew Pumphrey to talk about everything valves – problem areas, materials, sizes, angles, valve jobs, seats, and even springs. Check out this latest Intellectual Horsepower episode brought to you by SBI.

Valves and Seats

When it comes to engine components working together, there are few areas that share the same level of relationship as the valves and valve seats. The factors that affect this duo’s ability to reside in harmony inside an internal combustion engine encompass everything from material compatibility to thermal conductivity.

Valves and Seats

The valves and seats in an internal combustion engine play a central role in engine breathing, compression, performance and longevity. It doesn’t matter if an engine has two, three, four or even five valves per cylinder or if the engine is gas or diesel because the valves all do the same thing: they open and close to allow air into the cylinders and exhaust to exit the cylinders.
