Engle TCS20 Turbo Camshaft 397/392 Lift 294/284 Duration 112 Lobe Center

Description

The Engle TCS20 camshaft is a turbo-specific performance grind designed for stronger mid to upper RPM power while maintaining good boost response in air-cooled VW Type 1 engines typically in the 1776cc - 2276cc+ range. Reduced overlap improves boost efficiency and drivability, making it well suited for more aggressive street and street-strip turbocharged applications. The TCS20 delivers a slightly lopey idle compared to smaller turbo grinds while offering improved top-end power and strong performance under boost.
