All you wanted to know about top fuel dragsters

Pretty insane.

The speed specs are pretty nuts when compared to our daily drivers.

- 05 seconds 74 mph @ 21 ft
- 1.0 seconds 113 mph @ 75 ft
- 1.5 seconds 162 mph @ 125 ft
- 2.0 seconds 212 mph @ 231 ft Fuel consumption is at 95 GPM
- 2.5 seconds 248 mph @ 420 ft clutch plates are starting to weld together.
- 3.0 seconds 275 mph @ 650 ft 5,000 lbs of down force acceleration down to 5g's
- 3.5 seconds 293 mph @ 783 ft many of the spark plgs have burned away so the engine is dieseling.
- 3.85 seconds 315 mph @ 1000 ft

Apparently the engine has to be rebuilt after every run. New plugs, pistons,
conx rods, clutch plates ... etc They make 8 runs per race so they have 8 engines on the truck. The rear tires are good for about 2 miles (8 runs) and cost $700 a piece.

The speed is what gets me. In 1 second they have exceeded any US speed limit by a good clip, they have only traveled 75 feet and only 1 second has passed. That is just nuts to me. They are leaving the line at 5Gs. A carrier launch is 'only' 2.5 G's. How the heck do you stay conscious at 5G's?

This impresses the heck out of me.
