How much horsepower does roller lifters add?
How much horsepower does roller lifters add?
It reduces friction if the flat tappets used 2 hp at 5,000 rpm and the roller tappets use 1 hp at 5,000 rpm you free up 1 hp call it added if you want. If the cam is a different profile that may give a different power figure depending on the existing cam it may even be a drop in power not an increase.

What is the advantage of a roller cam?
The big advantage roller cams have over their flat-tappet cousins isn’t the reduced friction most people immediately think of, it’s increased tappet velocity (i.e., faster ramp rates). This increased velocity, as much as 30 percent, equates to more power.
Can I put roller lifters on a flat tappet cam?
It is possible to run hydraulic flat-tappet lifters on a solid flat-tappet cam, and hydraulic roller lifters on a mechanical roller cam. Running hydraulic lifters on a solid grind raises the rpm points at which peak power and torque occur compared to using solid lifters on the same solid cam.
Can I use solid roller lifters on a hydraulic roller cam?
It is possible to run solid flat tappets on a hydraulic flat-tappet cam and even mechanical roller lifters on a hydraulic-roller cam. Using solid lifters, even with the existing hydraulic springs, enhances top-end stability and fights the onset of valve float.
Are Crower roller lifters rebuildable?
Crower roller lifters are rebuildable. EDM Technology allows Crower engineers to place a precision hole directly from the oil band to the needle bearings. Delivers more oil to critical, high load areas for greatly improved cycle life. Specify “H” after lifter part number to order (ex. 66200H-16).
What are the features of endenduramax solid roller?
EnduraMax features Needleless Bearing Option and High Pressure Pin Oiling. Say hello to the latest addition to our line of highly durable solid rollers! This premium roller series includes NBO (Needleless Bearing Option) and HIPPO (High Pressure Pin Oiling).
What is the best blade height for a Crower lifter?
Seat Height Blade Height Crower cutaway body lifters fit all raised lifter bores where .300” taller blades are required Crower rollers are available in all popular designs (full body and cutaway) as well offsets, body diameters.
What are the features of a crowing roller?
Crower rollers are available in all popular designs (full body and cutaway) as well offsets, body diameters. Utilizes longer, “control contoured” tapered needle bearings that deliver unsurpassed load capacity and correct for irregular tappet alignment.
