Curval, yep, 1/4 mile straight line acceleration. Just like the land drags. That engine in the pic above is a nitro engine. They don't work on a circle course.
Five thousand horsepower
The engine has to be completely taken apart and rebuilt after EVERY pass. Hugely expensive to operate. Until you've seen/felt a nitro engine run whether on land or water you just haven't lived. Standing 30 ft. away as they fire it up then switch over to nitro, the sound, your chest and clothes vibrating, the tickling in your ears. Then they goose it, instant throttle response. The newbies crowd around trying to prove their manhood. Then they get an eyeful of nitro fumes and cry like babies.
Drag racing is a true spectator sport. Walking around the pits is the best part of it. Drivers and crew are always friendly. Several offered for my kids to sit in their boats with the lid down. Try that at a winston cup or CART meet. Can you tell i'm an enthusiast?
