It’s no secret that the engineers at BMW strive to make each level of their M lineup the top tier in each segment. When it comes to the F80 and F82, the twin-turbocharged and liquid-intercooled grunt of the S55 coupled with the agility of the 3-series chassis is a killer combination that rockets these Bimmers to the top of the class. While the duo works on paper, in everyday use there is one aspect that does, quite literally, crack under the pressure—the charge pipes.
One of the main reasons the M3 is on another level is the S55’s ability to keep its cool, especially when it comes to the intercooling system. BMW equipped the F8X generation of the M3 and M4 with a state-of-the-art air-to-water intercooling system for a more efficient means of keeping the charged air cool, but before we dive into our plans for besting the F80’s heat exchanger, let’s take a look at what an air-to-water system even is.
Oil is the lifeblood of any vehicle. Its lubrication properties keep all the metal bits inside of the engine from shredding each other to dust. While the M3 and M4 rise above just about every other run-of-the-mill commuter car, nothing knocks them down a few pegs quite like overheated oil or oil that finds its way out of the system.
Any outdoor sculpture facing the elements is going to eventually tarnish. Sure, there have been advancements in materials and coatings, but grime and dirt building up on that piece of art is an inevitable consequence of being outside. Eventually someone is going to have to come by with a power washer to clean things up.
The situation is relatable under the hood of the F80 M3. The S55 is a work of art, but the unavoidable by-product of blow-by is constantly peppering the intake … Continue Reading ››
When it comes to sports sedans, enthusiasts and automotive muggles alike can easily recognize the pinnacle of the segment—the BMW M3. It’s not much of a surprise since the Bavarians have been pouring just about every ounce of their engineering prowess into the M3 since 1988 to become the benchmark. The F80 is the latest iteration of BMW maintaining the bar.
