If you're serious about performance, let me tell you about the ACL Race Series Engine Bearings. These aren’t just your run-of-the-mill bearings; they’re crafted with a unique blend of design, metallurgy, and engineering that really stands up to the demands of high RPM driving. I've had my hands on these bearings, and trust me, they deliver exactly what you’d expect from top-tier performance parts.
First off, the high-strength overlay plate is thinner than what you might find elsewhere, which actually helps with fatigue resistance. It’s a small detail, but it makes a real difference when you’re pushing your engine to its limits. Plus, the hardened steel backs on the rod bearings provide solid support for the lining, ensuring that everything stays in place even when the going gets tough.
One of the standout features is the increased crush, which boosts bearing retention. This means they fit snugly in their housing, reducing the chances of any unwanted movement. And speaking of fit, the elimination of flash plating on the backs of the bearings really enhances heat transfer, which is crucial when you’re running at higher temperatures. It maximizes the grip between the bearings and their housing, allowing for better performance overall.
Now, if you’re revving high, you’ll appreciate the increased eccentricity that compensates for bore distortion. This helps in forming those vital hydrodynamic oil films that keep everything lubricated and running smoothly. The 3/4 grooved main bearings are another thoughtful touch—they optimize the load-carrying surface area and improve oil flow to the conrod bearings, which is key for keeping your engine happy.
And let’s not forget about the tight, consistent wall tolerances that help maintain clearances. It’s all about precision, and these bearings deliver. Plus, they come with enlarged ID chamfers where needed, accommodating those larger fillet radii on performance crankshafts. It’s all about making sure everything fits just right.
To sum it up, ACL Race Series engine bearings are built for dependability under high RPM conditions. They’re designed for a range of popular applications, including the Volkswagen Golf R from 2010 to 2018 and the Audi TFSI 1984cc 4-cylinder (CDL). If you’re looking for a reliable upgrade that can handle the heat and keep your engine performing at its best, these bearings are definitely worth considering.
