'Everybody wants to talk about bottom-of-the-page camshafts with calendar-length duration figures and valve lifts approaching 31/44 inch. With all this thinly veiled aggression going on in the ...

This file type includes high resolution graphics and schematics when applicable. Proper size and installation extend the life of gas springs and dampers. Gas springs help lift loads or open doors or ...

A novel approach using computational fluid dynamics techniques provides a way for determining the characteristics of gas passing through a gas-lift valve. In the method, CFD calculations numerically ...

For mild street engines, stock valve springs are more than adequate. But if you've screwed in a big bumpstick for strip-banging or banzai runnin', then pay attention. Our plan was simple: Install a ...

Obviously, these valve-control-related issues, associated with insufficient valvespring pressure, are the reason why camshaft manufacturers offer valvespring upgrades. The obvious answer might seem to ...
