What size engine does a Top Fuel dragster have?
A Top Fuel Dragster—distinguished by a supercharged, custom-built, 500-cubic-inch engine—boasts 11,000 horsepower and burns nitromethane. By contrast, a Top Alcohol Dragster’s output is about approximately 4,000 hp. Most alcohol dragsters burn methanol, although a few burn ethanol.
What RPM does a Top Fuel dragster idle at?
T-minus 90 seconds – Burnout & Backup After 15 seconds idling at 2400-2500 rpm, the signal to roll though the water box is given. “The fuel lever goes back to full and after three tire rotations through the water, I release the clutch to do the burnout.
Why are Top Fuel dragsters so loud?
Top Fuel dragsters are the NHRA’s loudest cars, in part because of the way the engine is mounted. The NHRA once allowed a team of seismologists to stand at the starting line to measure the race the way they would measure an earthquake — the two cars rated a 2.3 on the Richter scale [source: McGee].
