What Does It Mean For A Car To Be Cammed??

“Cammed” means that they put in a different camshaft.

The sound changes because the cam is the heart of the engine.

It dictates how much air is taken in and put out and for how long, to put it bluntly.

There are a couple people in the process of swapping now, and several that have already swapped.

What does a cam do for performance?

Whether the camshaft is in a pushrod engine or an overhead cam engine, it controls the opening and closing of the valves. This, in turn, controls the flow of air and fuel into and out of the engine which determines engine performance, fuel economy and emissions.

What does putting a cam in a car do?

The camshafts have the job of opening the valves that let air into and exhaust out of the engine. The camshaft uses rotating lobes, called cams, that push against the valves to open them. Springs on the valves return them to their closed position.

Does camming a car make it faster?

Performance cams increase the duration and timing of the valve openings during the engine stroke, increasing horsepower and making your car accelerate more quickly. You’ll idle slightly rougher with a performance cam, but get a throaty rumble that’s desirable for some gearheads, depending on your vehicle.

Why do camshafts make car louder?

The impacts of the valves on the seats make noise. Steeper angles and stiffer springs, louder impacts, louder valve train. I as always amazed at how much the valve train contributed to the over all engine noise. A cam can make an engine louder.

What makes a car lope?

Lope is a result of the intake and exhaust valves both being open at the same time. This is called overlap. Mild cams have little or no overlap at any valve opening that makes a difference.

Does a bigger cam give more power?

generally the bigger the cam, the more power it makes it top. you can somewhat change that by retarding the cam to make more power down low. Actually, retarding a cam should move the power farther up in the powerband, usually a few extra HP up top (or few more RPM’s) in exchange for a few lb-ft down low.

Why would a camshaft break?

A broken camshaft is usually caused by a connecting rod or other rotating part coming loose and striking it. Sometimes the cam will break after a short time of use because of a crack or fracture in the cam due to rough handling during shipping or improper handling prior to installation.

Is it safe to drive with a bad camshaft sensor?

If the engine appears to function normally, as before, it is likely OK to drive it. However, if the engine starts to misfire (you would see a flashing check engine light) then it is NOT OK to drive it all without risk of damage. Diagnostic Trouble Codes can never be used to “directly” condemn parts.
