Do roller rockers actually make a difference in engine performance?
A common misconception is that roller rockers are better than their stock counterparts because they use bearings instead of bushings. The resultant loss of friction supposedly makes power. That’s just not the case, as there’s a great deal more going on.
Do roller rockers make more power?
For engine applications that demand a step up, replacing the stock stamped or cast steel rockers with aluminum roller rockers will typically produce a gain of 10 to 15 hp with the same lift ratio, and even more of a power gain with a higher lift ratio.
Do roller rocker arms add horsepower?
Whether you’re dealing with a mostly stock junkyard small-block or a highly modified race engine, rocker arms play a big role in freeing up horsepower and helping reduce friction in the valvetrain.
Why are roller rockers better?
A roller rocker has a small roller that rolls over the end of the valve stem. This virtually eliminates side load on the stem and greatly reduces wear. Another area of high friction and wear is between the rocker arm and rocker shaft.
How much lift do 1.6 roller rockers add?
With a 1.6:1 rocker, this gives us 0.508-inch valve lift at max lift, an increase of 0.031 inch. It doesn’t sound like much, yet it was enough to show a sizeable gain, mainly because it increases the amount of time that the valves are open at higher lifts, allowing more air to flow through the heads.
Can you use roller rockers on a flat tappet cam?
The two don’t necessarily need to be used together. Roller camshafts and lifters can be used in an engine that features nonroller rockers; by the same token, roller rocker arms can be used in an engine that features a flat-tappet solid or hydraulic camshaft.
How much HP do roller lifters add?
The total difference in horsepower between the solid roller and hydraulic roller setup is just slightly over 8 horsepower.
