When your hunt for automotive performance gains turns to upgrading your transmission and shifting performance, it’s important not to overlook the “brains of the transmission” — the valve body. In this edition of Carl’s Tech Talk video series from Summit Racing, tech expert Carl Pritts will walk you through the process of modifying your transmission’s valve body. Transmission
Q: I built a 350 engine using parts from Summit Racing. At about 3,000 miles the engine would make a clacking noise at startup, but only when the engine hadn’t been run in a while. When the oil pressure came up (60-70 pounds), the noise stopped in a second or two. At about 3,500-3,800 miles, I
(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,
Q: I have a street/strip 1969 Camaro with a 427 big block that puts out about 475 horsepower at 6,000 rpm. The engine has an 800 cfm Holley fed by a factory mechanical fuel pump running fuel through a 3/8-inch fuel line. I have seen quite a few mechanical and electric fuel pumps that are rated
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
Racing season is winding down in many parts of the country, but that doesn’t mean your remaining race fuel has to go to waste. Although race fuel is often stored for several months between racing seasons, there are steps you can take to keep it as fresh as possible for next season. According to the folks at Sunoco
Because we must understand how certain parts work to make the best choices for our specific application, this edition of Carl’s Tech Talk video series from Summit Racing begins with tech expert Carl Pritts explaining the finer points of torque converter operation. The rpm at which vehicles begin to move can be changed by modifying
Q: I have a couple of problems I hope you can help me solve. I have a 1969 383 Mopar that shakes right after the first cold startup, but only if it’s been longer than 24 hours since the engine was last running. I was told this might be because the electric choke on my Edelbrock
