Building a 1000hp sleeper BMW.from @bixmation

If money wasn't a problem, this might be the most ridiculous luxury daily driver you could build. First, start with a BMW seven fifty I. To everyone else, it's just a massive executive sedan with massage seats, ambient lighting, and a back best you could practically live in. But underneath the hood sits BMW's 4.4 liter twin turbo n 63 v eight, already making 523 horsepower from the factory. And we're about to make that number look embarrassing. First, pull the engine and build the bottom end with forged pistons, stronger connecting rods, upgraded bearings, and head studs because the goal isn't just making a big no number, it's keeping the engine together when you actually use it. Next, ditch the factory turbos for a serious pair of upgraded hybrids capable of supporting a four digit horsepower build with the right supporting modifications. Add upgraded high pressure fuel pumps, supplemental fueling, ethanol compatible fuel lines, and a custom ECU calibration. Now you're aiming for roughly 1,000 horsepower at the crank, but making power is the easy part. Keeping a two ton luxury sedan alive at that power level is where things get expensive. The factory ZF eight speed gets built clutches and upgraded internals, while the x drive system gets whatever reinforcement your transmission builder says it needs. Then come larger heat exchangers, upgraded charge cooling, a better radiator, and improved oil cooling, because nothing kills a big power BMW faster than heat. Keep the exhaust quiet, the factory wheels, and every piece of that ridiculously comfortable leather interior. Maybe add some sticky tires, but absolutely no giant wing or obnoxious body kit. The whole point is that nobody suspects anything. On a conservative tune, you're cruising to dinner with the heated steering wheel on, listening to music, and barely hearing the engine. Then, you switch to the aggressive map, and this thing goes from chauffeur car to absolute missile. Imagine pulling up next to a supercar in what looks like your grandfather's 750 I. They hear a little turbo whistle, the light turns green, and suddenly, that quiet executive sedan is gone. So tell me, would you build this?
