I find both equally impressive.

Top fuel is crazy horsepower like nothing else, and F1 engines are crazy engineering like nothing else.

Porsche's TAG twin-turbo F1 engine from 1988 was 1.5 liters and put out 1050 bhp in qualifying trim. They would run them for multiple 2-hour races plus qualifying. When I went to the Belgian GP in 2004, they were running 3 liter V-10's turning at about 19000 rpm with 900hp, and I seriously thought my ears were going to bleed from the shriek of the cars going by.

The most impressive thing in top fuel is the clutches. Making 8000 hp is one thing, getting it on the road is another. The decreased times in top fuel recently have come because of clutch development more than anything else . 8000 horse is still a punch in your face when they launch off the line, though.



How did the math pencil out, slabby?
