Rebuilding a drag racing engine is no small feat. These engines are complex, hugely powerful, and need to be rebuilt often. But what does it take to rebuild one, you ask? Well, here's a seven-minute time lapse of a complete teardown and rebuild of an 11,000-HP supercharged top-fuel dragster engine.
Typical street-car engines can run for hundreds of thousands of miles, but top-fuel dragster motors need rebuilds after every quarter-mile run. That might seem ridiculous, but the seals only last one full-throttle pull, and the spark plugs disintegrate during the run. According to , most teams can completely disassemble then reassemble an engine within an hour, usually several times throughout a race weekend.
The engine featured here is from Tony Schumacher's US Army-sponsored car, being rebuilt by the Don Schumacher Racing team in Brownsburg, Indiana. It's cool to see just how many similarities a top-fuel dragster's engine shares with a normal street car, and what's different. Check out the full clip below.
