Are VCM cams any good?

The VCM 714 camshaft is designed for street/strip use & makes the most our of your boosted LS engines high end capabilities. This is a tough camshaft that will work perfectly with CNC ported heads….VCM 5SC Cam Specs.

What is a good camshaft duration?

Measuring duration at 0.050-inch tappet lift has become standard with most high-performance cams. Most engine builders feel that 0.050 duration is closely related to the rpm range where the engine makes its best power.

How much horsepower does a Stage 2 cam add?

Stage 2: this is typically referred to an engine with a performance cam upgrade as well as the other components within a Stage 1 combination. A typical Stage 2 has generally +20-25% more HP than stock. Stage 4: this would be a moderate compression big bore combination.

What is considered a mild cam?

In general, a stock replacement camshaft with duration of less than 200 degrees will have a lobe separation angle of more than 114 degrees. An RV or towing camshaft, which is considered a mild performance or an economy cam, will often have a narrower LSA, between 112 and 114 degrees.

How much HP can a cam give you?

Does a camshaft increase horsepower? Yes, a camshaft adds 10 to 20 horsepower depending on the setup. To get the full potential of the high-performance camshaft, you’ll have to swap out additional components like the air intake, exhaust manifold, injectors, and valve heads.

How much HP does a Stage 2 cam add?

How much HP does a Stage 2 camshaft add? Stage 2 involves upgrading the camshaft, but it also requires you to upgrade the intake and exhaust system as well as remap the ECU to complete Stage 1. When both stages are completed, you can get 20-25% more power out of the engine.

What gives a cam a choppy idle?

Registered. LSA (lobe separation angle) determines the choppiness, it has to do with the overlap of when both valves are open, as in when the exhaust valve is closing and the intake valve is opening to pull fresh fuel in on the intake stroke after pushing out the burnt fuel.

How much horsepower will a Stage 3 cam add?

Stage 3 will have up to 40% more power compared to the stock setup, but to get there, you’ll have to complete the Stage 1 & 2 modifications, and mild big bore of the engine.

What makes a cam sound lumpy?

what makes the cam have that lumpy sound? The overlap of the exhaust valve closing and intake valve opening causes the engine to be inefficient at low speed which results in the lumpy idle. The closer the Lobe Seperation Angle the more the overlap, the more duration the more (typically) the overlap.
