What does a higher lift camshaft do?

Lift describes (usually in millimetres) how far the valves open – the higher the lift, the taller the camshaft lobes have to be to achieve this. More lift gives more flow, which, in turn, usually gives more power, and with only very minor ill-effects to performance elsewhere in the rev range.

Is a higher lift cam better?

Designing a cam profile with more lift results in increased duration in the high-lift regions where cylinder heads flow the most air. Short duration cams with relatively high valve lift can provide excellent responsiveness, great torque, and good power. But high lift cams are less dependable.

Can a bigger camshaft give you more power?

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.

Do camshafts increase rpm?

Fortunately, choosing the right aftermarket performance camshaft for your particular combination will deliver big rewards. Increased power, increased torque, increased rpm potential and a broader powerband are just a few of the benefits that could result from choosing the right cam.

What makes a camshaft choppy?

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. Most GM cams come on a 112, 114 or 116 LSA.

Does a fuel pump increase horsepower?

The technical answer is yes; fuel injectors can add 10 extra horsepower at peak. However, for some car owners, that minimal difference does not offset the increased cost and complexity of switching to fuel injectors or upgrading the existing stock fuel injectors.
