PHR PRODUCT TEST: COMP CAMS SHORT-TRAVEL LIFTERS

摘要

In the mid '80s, when hydraulic roller lifters came into widespread use, they offered many advantages over flat-tappet hydraulic and flat-tappet solid lifters. From a wear standpoint, they pretty much lasted forever, and for performance they offered a lot more area under the curve than flat tappets. But even then, the solid roller lifters used in race engines trumped the hydraulic roller in most areas, especially for rpm range, and flat-out power.
