Back in the day, low-pressure fuel delivery systems were the norm. As carburetors evolved and fuel injection came into play, fuel pressures increased and low-pressure systems became common. However, low-pressure fuel systems remain relevant because many vintage cars use Weber or Stromberg carb setups. Aftermarket low-pressure pumps and regulators are also used to replace OE parts for
[portfolio_slideshow id=59301] Few of us give consideration to how and why battery mounting can be used as an advantage. We know that the majority of drag cars and many street/strip machines have batteries mounted out back, but there are some specific factors to think about. Directional Battery Mounting The direction a battery is mounted can
What is cavitation? You’ve probably seen the term thrown around in reference to fuel system components, but do you really understand what it is and why it’s bad? According to FUELAB, it’s the single most common failure in high-flow fuel systems and warrants a closer look. What does cavitation mean? What causes cavitation? What are symptoms of cavitation? FUELAB’s
It can be incredibly frustrating when your vehicle won’t start. It can be even more frustrating trying to figure out why. Morris Rosenthal created a diagnostic flow chart to help people troubleshoot the possibilities. We found it, liked it, tweaked it, and are now sharing this infographic with you. Your very own swear-word-reducing, stress-relieving roadmap to
OPTIMA Batteries are among the most-trusted and popular automotive batteries on the market. One of the great things about OPTIMA’s AGM-style batteries is their extremely low internal resistance. This allows very high amperage output enabling the battery to power your accessories longer and deeper than a traditional battery while discharging it at the same time. But
Forget gasoline or ethanol. Your car doesn’t run on petrochemicals; it runs on electricity. And for the most part, the power source in that car is a battery (or two). Over the years, battery technology has advanced rapidly. Because of this, we figured the time was ripe to take a closer look at the world
Maybe we should’ve called it “stroker science.” There is, after all, a formula involved in creating a stroker engine. Things like bore size, overbore, crankshaft stroke, and connecting rod length must all work together to produce the coveted added displacement without nightmarish clearance problems. Some stroker combinations can be done with factory parts; others may require custom
If you’re driving an older vehicle with sealed-beam headlamps you’ve probably noticed how much brighter modern headlights have become. Don’t despair; there is a simple headlight mod that can make your headlights work better. Here’s the issue: the traditional way manufacturers run power to the headlights is from the battery, up to the dashboard, through
Congratulations, you’ve settled on a nitrous system. There are any number of great systems on the market, and choosing a nitrous kit that’s right for your vehicle can be an accomplishment. If you watched our earlier video post, Your Top Nitrous Questions Answered, you know there are specific horsepower guidelines for picking the right system,
Following the rules is sometimes not as fun as not following them. But when discussing torque sequences and recommended torque specifications, vehicle owners will have a happier life by following the rules. Torque specifications vary by fastener brand, lubricants used, and other factors, but the correct head bolt torque sequence usually remains constant for each
