How much horsepower does a roller cam add?

How much horsepower does a roller cam add?

The total difference in horsepower between the solid roller and hydraulic roller setup is just slightly over 8 horsepower. In fact, both cams actually made about the same ft-lbs of torque at the same RPM.

Does a roller cam make more power?

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.

Is a roller cam worth it?

The one draw back is that roller cams cost quite a bit more than your typical flat tappet cam. So compared to a typical $65 – $75 set fo flat tappet lifters, a set of roller lifters is going to set you back a bit more $, but in the end, for what you gain in performance & reliability, it is well worth it.

How much HP gain with roller rockers?

With the baseline laid down, we moved on to a set of Comp Cams 1.5:1 roller rockers. At the same 6,000-rpm peak, we made 401.1 hp and 412.9 lb-ft of torque, a gain of 11.2 hp and 5.9 lb-ft of torque.

Can you run hydraulic roller lifters on a solid roller cam?

To successfully run hydraulic-roller lifters on a solid-roller profile generally requires that the solid cam profile be a tight-lash grind (under 0.020-inch hot) in the first place, with less than 30 degrees difference between the 0.020- and 0.050-inch duration specs.

Can I put a roller cam in a non roller block?

So, in order to install a roller cam into a non roller block you have two options: 1. Smaller base circle cam which gives you more distance to the center of the oil gallery for the added height of the roller lifter. You can use stock lifters and dog bone retainers.

Do you need roller rockers with a roller cam?

Roller Rockers. Roller rockers, while offering reduced friction operation compared to conventional rocker arms that pivot on a ball, with direct frictional rub at the valve tip, are not automatically required with the use of a roller camshaft setup.

Do roller rockers improve 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. The loss of friction may help things last longer, but it’s not going to measurably add power.
