It's common in almost all motorsports.

A good example of something somewhat similar is on drag racers. They expand as they get faster but they still hold the bead, but in F1 they're mostly moving side to side instead of up and down.

Top fuel dragsters are some of the most insane cars

Absolutely! If you ever get the chance, definitely go watch. The punch you get in the chest when they launch is crazy.

Plus the pits are open so you can watch them rebuild engines between runs. Super cool.

Top fuel makes more downforce on the rear wing than multiple F1 cars. The roar is something else though, I explain it as a huge bomb that keeps exploding cause thats how it feels in your chest and it literally shakes your eyes when they pass you. The pits are the best for newbies cause you make them stand there while you get tear gassed when they fire the motors up and its awesome to see the whole crowd jump back when they whack the engine https://youtu.be/NaEvWfonLiY

cause they go faster - they basically have no diffuser, just huge wing

True, but that wing is not much larger than an F1 wing but it makes close to 6.5 tons of downforce doing it. Hell they make a half ton of down force purely from the exhaust. Everything on a Top Fuel rail is just mind blowing from fuel flow to air flow to horsepower and g force, everything is kicked up a few notches. I dont know how efficient the motors are, but ~13000 hp from 8,2 liters is pretty damn impressive.

sure impressive, but for me it's lacking that "poetry" (fine engineering), efficiency and it just runs ~4-5 sec in straight line and that's that.

Idk man, I think engineering a car and engine that can handle burning 60liters of fuel in 3 seconds is pretty damm fine engineering. Even a chassis that long that can handle 6.5 tons of down force and tires that allow accelerations of 8 G which is twice the maximum acceleration of the space shuttle is pretty fine engineering to me.

Watch the video I linked above about it. It might change your mind.

I am not a huge fan of drag racing either but top fuel is something else and I have a ton of respect for them.

I saw a document about it, but I mean they only focus about one (or rather 2) things - go fast in straight line on perfectly flat road and then brake.
