Trent Goodwin recently reported on Comp Cams’ new Evolution Hydraulic Roller Lifters. He said, “These are the first lifters ever created using our patented Hydraulic Cartridge Technology.
“This is an all-new, clean-slate design by Comp Cams to meet the performance and durability demands of modern street and performance street engines. A combination of a self-contained hydraulic cartridge within a thick-wall lifter body and accompanying reduced oil volume that is less affected by oil aeration delivers the most consistent bleed rates between each lifter on the market.
“The smaller volume in the hydraulic cartridge greatly reduces start-up noise, and a precision-controlled bleed down rate ensures excellent performance at high rpm. The cartridge design also allows for an incredibly stiff lifter body, greatly reducing body distortion and further ensuring consistent hydraulic performance. Another industry first is the fact that the hydraulic element is serviceable, allowing anyone to rebuild lifters in their own garage.”
