When it comes to building stainless steel braided lines with aluminum hose ends, it’s a polarizing task. Some love doing it, and some hate doing it. While we fall into the former camp, we recently ran into some real-world struggles while helping out with a project for one of our sister magazines. We were building some PTFE AN lines for the fuel system of a Chevelle on the car when our typical “engine dyno privilege” popped up.

When it comes to pistons, one of the most common discussions regarding piston material is cast versus forged. Or, debate between the two primary alloys used in forged pistons, 4032 and 2618. However, there is another material debate on the rise lately, and that is billet vs. forged pistons. Over the past half-decade, the popularity of billet pistons has been on the rise, so we reached out to MAHLE Motorsport to find out why that is. Forging AheadFirst, let’s look at the process of forging a piston.

We’ve spoken about it in the past — the modern evolution of piston and piston ring designs has absolutely made making bigger horsepower numbers easier than ever. Where the common thought process decades ago was that thin rings were too weak to last — let alone handle forced induction — we are now seeing thin rings in production-line engines that would have made race engines blush in decades past.

Likely, you are familiar with at least the basic concept of an oxygen sensor. An oxygen sensor — or O2 sensor as it’s sometimes called — detects the amount of oxygen in your exhaust, post-combustion, in order to determine your air-fuel ratio. Oxygen sensors come in two variations: narrowband, which are on many OEM EFI systems, and utilize a 0- to 1-volt signal, and wideband, which utilizes a 0- to 5-volt signal, making them a far more precise option.
