How do I know what camshaft to use?
The rpm range is the range where the engine performs best. When selecting a camshaft, choose one with an rpm range that matches the other components of your vehicle and its intended use. Follow this link for more about Basic Operating RPM Range.
What cam should I use?
Cams with durations in the 195 to 210 degree range (measured at . 050˝ cam lift) are usually considered best for stock unmodified engines and those with computerized engine controls. Once you go beyond 210 to 220 degrees of duration, intake vacuum starts to drop.
What is considered a stage 3 cam?
The LS1 Stage 3 camshaft was designed for enthusiast who want to increase power while maintaining excellent drivability and manners. This cams can be used with stock torque converters, stock rear gears, stock intake manifold, stock exhaust manifolds etc.
What gives a cam a rough idle?
The reason race cars have that rough idle is because the engines used are designed for high-rpm operation. The reason you want to stay away from an increase in lobe lift is because of the changes youll need to make to a stock engine if the cam has more than approximately . 460 inch lift.
What is a good camshaft duration?
Performance cams typically have durations ranging from 220 up to 280 degrees or more. The longer the duration, the rougher the idle and the higher the cam’s power range on the rpm scale. A cam with a duration of 240 degrees of higher will typically produce the most power from 3,500 to 7,000 rpm.
Does a cam reduce mpg?
A cam, or an good Heads and cam package really won’t affect your highway mileage much IF it is properly tuned after the install, and IF you don’t hammer it all the time! You will notice a significant drop in your stop and go traffic mileage.
How much power does a Stage 3 cam add?
Summit 8710 Stage Three Cam: 549 HP and 492 LB-FT.
What makes a cam more choppy?
Its is true that the LSA has something to do with cam sound but its more about overlap more than anything. Overlap is the sole reason why a cam will “chop” or not. Sure, LSA can control overlap but its the mixture of duration and LSA that fully controls the amount of chop a cam has.
What is cam lope at idle?
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.
What is a double overhead camshaft?
In a double or dual overhead cam, one camshaft operates the intake valves and a second, separate camshaft operates the exhaust valves. The V-shaped engine will, once again, need two cams for each side to make it work. While the engine contains four camshafts in total, it’s still considered a double overhead cam.
What does a cam position sensor do?
The CAM sensor or camshaft position sensor’s role is to signal the ECM the camshaft position. The crank and cam sensor operates in sync with eachother. The CAM sensor is frequently used in determining which injector to fire in a sequential system and for the COP or coil on-plug ignition systems coil firing event.
What is a camshaft intake?
In this regard, what is a intake camshaft? A camshaft on an internal combustion heat engine is a device that controls both the input of fuel and the expulsion of exhaust fumes . It consists of several radial cams, each displacing intake or exhaust valves. This camshaft is connected to the crankshaft via belt, chain or gears.
What is a camshaft valve?
In internal combustion engines with pistons , the camshaft is used to operate poppet valves. It consists of a cylindrical rod running the length of the cylinder bank with a number of oblong lobes protruding from it, one for each valve.
