Water-methanol injection (WMI) is a very capable form of fueling and cooling on turbo engines. Methanol is a high-octane fuel while water quickly cools temperatures due to its high specific heat capacity. Those are the two main benefits of N63 WMI, but it also comes with some risks. In this guide, I discuss BMW N63…
The BMW N63 isn’t an engine known for reliability. At least in the early years of its production. With the introduction of later N63TU, TU2, and TU3 variants, reliability got much better than the pre-technical updated variant. One of the most significant issues with the early N63 engine was fuel injector failure. The Piezoelectric injectors…
When the N63 4.4L twin-turbo V8 arrived on the scene in 2008, it was unquestionably one of the most advanced V8 engines ever produced. In fact, it still is to this day. BMW experimented with a new “hot vee” engine design which mounted the turbochargers and exhaust manifold between the cylinder banks, making it the…
The BMW N63 has been BMW’s premier non-M V8 engine for over 15 years now. The N63’s unique “hot-vee” design, with twin-turbochargers sitting between the cylinder banks of the engine, was innovative if not a bit problematic in the engine’s earlier years, with excessive heat – unsurprisingly – being one of the N63’s biggest problems….
It’s no secret BMW has made some excellent, fast high-performance cars. However, BMW has mostly kept away from horsepower wars, and has instead relied on building “The Ultimate Driving Machine”. Often, it’s about the handling and overall driving experience over pure power and straight-line speed. That doesn’t mean BMW hasn’t built some incredibly powerful engines,…
Previously, we wrote a post about modding BMW N63 engines to make 500+whp on stock turbos. These are already impressive results. However, that’s simply not enough power for some N63 owners. That’s where N63 and N63tu upgraded turbos come into play. Although, upgrading N63 twin turbos does come with additional risks. In this guide, we’ll…
What is the max boost the stock N63tu twin turbos can handle? How much PSI can the N63tu twin turbos handle without completely killing longevity? We see the questions asked often, and they’re valid questions. However, there is not always a perfect answer. Regardless, we will lay it out as clearly and straight-forward as possible….
A dual cone intake system for twin turbo BMW’s are one of our favorite bolt-on mods. However, the N63 is a bit different. The stock N63 intake system is efficient from the factory. That leads us to ask, “are dual cone intakes worth it?” Let’s dive in and examine the benefits to an upgraded intake…
The N63 is a force to be reckoned with in the turbo era. It’s a stout motor from the factory coming with 402-523hp, depending upon the specific N63 variant. Though, for some, this simply isn’t enough power. Simple bolt-on mods are a popular option for those looking to make extra power. In our opinion, downpipes…
BMW is showing their commitment to the N63. The N63 was released in 2008 and remains in production as of 2020. However, the N63 is almost a completely different engine compared to 12 years ago. Really, the only thing that hasn’t changed is the 4.4L twin turbo V8 design. Let’s dive in and examine the…
BMW has shown their commitment to the BMW N63 engine. It was first released in 2008 and remains in production as of 2020. The twin turbo 4.4L V8 N63 received a few updates along the way. 2012 saw a large improvement (N63TU) with the addition of valvetronic, revised turbos, lighter pistons, forged rods and crank,…
When the BMW N63 engine was first released in 2008, it was one of the most advanced V8 engines in the world. In addition to the N63’s entirely aluminum construction and implementation of a direct injection fuel system, it was the first engine in the world to use a “hot-vee” engine layout. This engine has…
