Got seven minutes spare? Good. Because thanks to the power of timelapse, that"s all you need to see a Top Fuel dragster"s 11,000bhp engine completely stripped down and rebuilt. It"s also remarkably satisfying. And quite mesmerising. Like some sort of mechanical ASMR for your eyes. But even without the fast-forward capabilities of timelapse, these guys work fast. At a race weekend, they have to strip down and rebuild an engine after every single run. Every. Single. Run. Given the crazy power and forces involved, engines start tearing themselves apart as soon as the driver hits the go pedal. Once you have deployed the bomb you"re strapped to, the pistons, rods, bearings, crank, and every other greasy bit has lost a chunk of its life. Many parts are capable of surviving more than a single run, but no team is willing to press its luck by making even a second run without checking everything first. That"s why a Top Fuel engine is completely torn down in 75 minutes by a crew consisting of seven to nine members.
