What is the Stoichiometric Point? And Why Is it Significant?

1 week ago | enginelabs.com | Scott Parker

Experienced tuners know that the stoichiometric point (or stoichiometric air-fuel ratio) of a fuel is the exact proportion of air and fuel at which a complete, balanced chemical reaction occurs, meaning all the fuel is burned using all the available oxygen in the air— no excess fuel or oxygen remains. It’s a theoretical value, but if you actually tuned to the stoichiometric air-fuel ratio under load, you would most likely create some ventilated blocks and pistons.

Smokey Yunick, a legendary figure in motorsports, was renowned for his innovative and often unconventional approaches to engine design and performance enhancement. His techniques, while groundbreaking, frequently sparked debate regarding their practicality and adherence to regulations.Hill Country Performance & Machine in Spring Branch, Texas, got ahold of a Smokey Yunick Hot Vapor engine and a boatload of other parts, and are releasing content on all of it.
Tech Tip: Pressure Testing Your AN Lines At Home For Under $10

2 weeks ago | enginelabs.com | Greg Acosta

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.

Billet Vs. Forged Pistons - Manufacturing Processes Explained

3 weeks ago | enginelabs.com | Greg Acosta

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.

When you plan on pushing an engine hard, the components you select become very important. High-horsepower engines need high-quality connecting rods so they can perform as designed and be reliable. Callies created its Ultra series of connecting rods with all the required features to be a top-tier high-performance connecting rod. If you’re running a supercharged or turbocharged engine, the Ultra Enforcer I-beam connecting rod is a great fit.
Feed The Beast: Drag-And-Drive Dual Fuel Systems

3 weeks ago | enginelabs.com | Brian Wagner

The line between street car and race car has been continuously blurred thanks to drag-and-drive competitors. Dual fuel systems have become popular in the drag-and-drive world because it gives racers the ability to run different fuel on the street and in race mode. In this article, we’re going to take a look at what goes into building dual fuel systems for a high horsepower drag-and-drive application.
Past Vs. Present — Comparing Piston And Piston Ring Designs

1 month ago | enginelabs.com | Greg Acosta

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.
Tech Thurssday: Explaining The Role Of An Oxygen Sensor

1 month ago | enginelabs.com | Greg Acosta

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.
