How long do dragster engines last?
How long do dragster engines last? 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.
How much does a Top Fuel dragster engine cost?
The cost of a complete top fuel dragster engine is in the $58,000 range depending on options. The engine will be stripped down to the bare block after every run and be rebuilt in a span of 40 minutes. The engine will be torn down and rebuilt 184 times in a year if the car makes it to the finals at every race.
