What does a Thumpr Cam do?

The basic science behind the Thumpr Cams is not a new one. The Thumpr line delivers true high performance engine sound by “tightening” the lobe separation angle of the camshaft. This creates more overlap between exhaust and intake events and more “cool” performance sound.

What makes a camshaft lopey?

You can make a stock cam lope if you get the overlap big enough by tightening the LSA but you can have a cam lope with stock LSA if the duration of the lobes are large enough.

What is a good cam 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.

What is the best cam for a 350 SBC?

For decades, COMP Cams CL12-600-4 or Thumper cam 350 has been the best performance cam for stock 350 chevy. Specifically, it helps to open and close the valve smoothly and generate strong force by improving the torque. Therefore, the CL 12 600-4 cam is an excellent choice for heavy-duty vehicles.

Are comp Thumpr cams any good?

As tested, this cam beat all the other test cams with both heads in every category but the absolute power peak. The Thumpr made the highest peak torque, the highest average torque, the highest overall average power, the best average numbers between 2,500 and 4,500 rpm, and the best numbers from 4,500 to 6,500 rpm.

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.

What does an oversized cam do?

A bigger cam will open the intake valve wider, allowing more fuel and air into the cylinder. The larger the cam, the more fuel that is let in.

What makes a cam 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.

What size cam Can I put in a stock 350?

However, only the COMP Cam CL 12-212-2 Magnum is designed for stock 350 trucks and is the best boosting horsepower. The special feature of this cam is the improved RPM and torque suitable for transporting large volumes.

Which is better TBI or carb?

So most TBI systems can tolerate radical cams with durations up to about 250° with much more finesse than a carburetor. The engine will run smoother, idle better, start easier and provide better throttle response and cold driveability with TBI than a carburetor.

How much HP can a TBI make?

around 275 hp
Stock small-block throttle bodies only flow around 500 cfm (compared with a stock Q-jet that flows 750 cfm). It’s possible to make around 275 hp with a stock TBI unit, so rather than go nuts on a heavily modified TBI, I’d suggest you start by making sure the existing TBI unit and injectors are in good shape.

How much HP does a high-performance cam add?

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 1 cam add?

How Much HP Does A Stage Cam 1 Add? A stage cam 1 can boost your vehicle by 50 to 100 horsepower. At the same time, it will also produce an increase in the torque output. Add a stage 1 engine to your car, and you’ll experience an improved RPM throttle response.

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.

What makes a cam sound choppy?

Is it necessary to degree a cam?

Pit Stop with Marlan Davis: Degreeing a custom cam ensures its maximum performance, helps prevent piston-to-valve contact, and protects against assembly error. The bigger the cam, the more important this is.

What does retarding a cam do?

Advancing or retarding the cam pushes the centerline of the camshaft to one side or the other of the crankshaft centerline. This changes the Timing of the valve opening and closing events, in relation to the position of the piston in the cylinder.

How much HP does a cam give you?

A quality camshaft can increase your car’s horsepower by 10 to 20 times, depending on the camshaft you opt for.
