What does an upgraded cam shaft do?
Upgrading the factory camshaft is a great way to gain more power and torque. It’s usually the next step after improving exhaust and the cold air intake. The numbers below are above what a tuned car with the stock cam and full exhaust upgrade would typically get.
How do you know when you need a new camshaft?
If your vehicle idles roughly, stalls frequently, has a drop in engine power, stumbles frequently, has reduced gas mileage, or accelerates slowly, these are all signs your camshaft position sensor could be failing.
How do I know if my flat tappet cam is bad?
Cylinder Miss A flattened cam lobe will often manifest first at low rpm, especially for engines with hydraulic lifters. At idle and low rpm, the valve is barely open even when the cam is brand new; when the lobe flattens out, the valve may not open at all until the lifter pumps up at higher rpm.
What causes a cam lobe to go flat?
Flat tappet cams are susceptible to damage due to a lack of zinc in modern engine oil, causing drivability problems as the lobe wears down. Flat tappet cams can be damaged by using modern engine oils that lack zinc and associated anti-scuff additives.
Does adding a cam increase horsepower?
Performance cams increase the duration and timing of the valve openings during the engine stroke, increasing horsepower and making your car accelerate more quickly. To install a new camshaft, you must expose the valve train by removing the valve cover and possibility the distributor.
How much HP does a cam add to LS3?
This camshaft is designed for all-out power and shows gains over the stock camshaft beginning at 3,100 RPM. The cam will pull really hard from 4,500 RPM up to the 6,600 RPM HP peak. This camshaft makes 93 flywheel HP more than the factory LS3 camshaft!
What’s the best way to install a camshaft?
Using your ratchet and socket, remove the center bolt on the camshaft gear and remove the gear from the camshaft. Step 16: Install the camshaft gear onto the new camshaft.
Can a camshaft be removed from a cylinder head?
Warning: When removing the camshaft, you want to make sure that it does not fall, as it can damage the bearings in the cylinder head. Step 15: Remove the camshaft gear. Using your ratchet and socket, remove the center bolt on the camshaft gear and remove the gear from the camshaft.
When do you change the timing of the camshaft?
The camshaft and crankshaft must be in perfect timing for the engine to run properly. Modern vehicles also utilize variable camshaft timing which can change when the valves open and close based on engine RPM, which can maximize horsepower and fuel mileage.
What is the purpose of degreeing a camshaft?
The purpose of degreeing a camshaft is to correct the errors and tolerances in the machining processes of the engine that can affect camshaft timing. COMP Cams suggests the intake centerline method as the most simple, quick, and efficient way to degree a new camshaft. Instructions for degreeing can be found later in this booklet. 3
