To truly understand how carburetors work, you first have to know Daniel Bernoulli. Bernoulli was an 18th century scientist who discovered that pressure is inversely proportional to velocity. This principle, called Bernoulli’s Principle, was originally applied toward fluid dynamics (think fuel flow vs. fuel pressure), but it also pertains to airflow. Specifically, as air speed increases,
I’ve read something about camshafts that some cam companies grind advance into the camshaft. I thought that you could only advance the cam once it was installed in the engine? How does the cam company grind advance into the cam? L.T. Jeff Smith: This is a great question. Everyone tends to look at the intake
When you think of an automotive cooling system, the first thing that likely comes to mind is your radiator…or maybe your cooling fan. The oft-overlooked fan clutch doesn’t get a ton of credit or attention, but it’s an essential piece of the cooling equation in many vehicles. It helps your cooling system operate effectively and your engine operate efficiently. But
Just how important is engine mounting in a drag car? Very. Consider the case of a common rear-wheel drive production line car: Typically, mounts are laid out in a three-point arrangement — two mounts on the side of the cylinder block and one at the very end of the transmission (usually on the tail shaft).
We’ve discussed previously what a drag following rules can sometimes be. We don’t always like doing what we’re supposed to. But when it comes to torque sequences and recommended torque specifications, rebellion isn’t half as cool (or financially responsible) as following rules. Torque specifications vary by fastener brand, lubricants used, and other factors. But the
Go to a dragstrip and you’ll see cars with beadlocks, tire screws, and what appears to be nothing holding the tire bead to the wheel rim. Some cars will run tubeless. Others will have tubes. Ponder all of the combinations, and the big picture starts to get a wee bit confusing So what tire setup
(Image/blog.driversed.com) The guys at StopTech have the science of brake systems down. So much so that they released a series of white papers that include everything from a basic glossary of brake terms to an in-depth look at the physics of braking. The topic that intrigued us the most was on common brake system myths. The paper
Before electronic fuel injection’s microprocessors and sensors revolutionized fuel delivery, carburetors fueled high performance machines using mechanical components like metering systems and boosters. Over the years, carburetor manufacturers have developed different metering systems which affect performance differently. According the Quick Fuel Technology, choosing the right metering system setup and booster style is key to optimizing the output and performance

While you can’t do much for the birds and baseball, there’s no law that says you have to stop riding. It’s not as simple as throwing on a coat,
It’s a dirty, thankless job, but someone (or something) has to do it. Deep down in the abyss of your engine bay, engine mounts are tasked with the tough job of holding your engine in place. They typically attach your engine to three or four points on your vehicle’s frame or subframe. An engine mount’s job description also
