Some folks are good with numbers. Some of us forget our own work phone extensions and occasionally blank on our PIN codes at the bank machine. For the latter group, OnAllCylinders contributor Lori Sams created this illustrated guide to engine firing orders. Firing order is important because it helps evenly distribute the power strokes along the
After another long winter, there’s no doubt you’re ready to get out and race. But what about your race vehicle and equipment? Has your chassis received its required certifications, if needed? Does it need to be re-certified? Does your bellhousing, transmission shields, and other safety equipment meet the proper SFI specifications. To help make
[portfolio_slideshow id=51924] Anyone who has ever drag raced knows that weather and track conditions can pretty much change by the minute. We also know that days at the track can be long, so the weather and the track you started out with in the morning can turn into a completely different beast by midday and evening. We’ve
Since the 1930s, hot rodders and performance car enthusiasts have relied primarily on engine coolants made from a mix of ethylene glycol, water, and corrosion inhibitors. While these water-based coolants have done an admirable job of cooling, history shows they can be prone to overheating, boil-over, and after-boil conditions at high operating temperatures. In other words, traditional water-based coolants are
Seasoned car guys can often identify cars at first sight. But how many of us can easily ID a vehicle’s rear axle? It’s a handy skill to have for sure — especially when you’re scouring a junkyard for a replacement axle or evaluating a potential project vehicle. We’ve put together this visual guide to help you hone
There are many factors to consider when purchasing an alternator. Things like amperage, voltage, pulley ratio, and wiring all come into play. We’ve covered some of these topics in this earlier post; however, we still receive many questions about alternators from readers. So we teamed up with the tech experts at Summit Racing to get answers for some of
Carb tuning has been a popular topic for us and our readers. Over the past few years, we’ve done several posts on the topic. The process itself can be a little tricky and very trying — especially for novice wrench-turners — so we thought we’d take the work out of finding good information. That’s why we’ve taken our
Everything I read says that the big rectangle ports for LS engines flow better than the cathedral ports. But then I know some pretty quick street cars running cathedral port heads. So for a 6.0L LS street engine, what would you recommend? My engine will be backed by a T-56 six-speed and 3.42:1 gears in
[portfolio_slideshow id=50283] Before the advent of the trans-brake, racers using automatic transmissions were at the mercy of the foot brakes installed in their respective cars. The stick shift guys had a big advantage, because they just had to engage the line lock (Roll Control) to leave consistently at an engine rpm where the car worked the best. Then
Most people know Jason Line for his on-track accomplishments. But Line and teammate Greg Anderson are hands-on gearheads. Both spend countless hours wrenching on their Pro Stock engines as well as their personal project vehicles. The guys are currently up to their ears with fuel-injection testing and tuning on their new Pro Stock powerplants, but Line recently worked
