The future is all about downsizing technology. We’ve all heard the familiar anecdote that our smartphones have more processing power than the computers that aided the Apollo missions. From computers and cameras all the way to something like cars, smaller has been the way. Why not downsize the intercoolers too, right? That was BMW’s plan by incorporating an air-to-water intercooler on the S55-powered M3 and M4. In a world of monstrous fin surface areas, BMW is focused on condensing. Let’s see just how they were able to pack all that cooling power into such a small core. … Continue Reading ››
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.
When it comes to the advancement of intercooling technologies, not … Continue Reading ››
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.
The Cool Factor
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 ››
