Thrusters better than fans?

Thrusters better than fans?

For drag racing if the thrusters blast behind you. But for racetracks, fans is what you want. You want road grip to make fast turns and fans suck the car onto the road. In real world conditions (not racetrack) though, you'd be sucking road kill, litter and everything else into your thruster fans, so that's probably why we'll never see it on a street legal car.

Elon's Roadster SpaceX package has side thrusters. So it'd help you go around corners. Again, not sure how this would work in real life because the limit is always tire grip, not engine power. So side thrusters would allow you to go faster around corners than tire grip would allow? So, you'd break traction, and now you're essentially drifting, and the side thrusters would compensate and push you around corners with little traction at some ridiculous side acceleration level. Meanwhile, cars in the opposite lane get blasted with high pressure air, and you hope you have enough thruster power to make that turn, else you'll be crashing into the tree on the other side of the road.

Um, yeah. Good luck with that concept. I suspect the SpaceX package, if it ever gets built (I suspect it won't) will be more of a marketing thing like the silly Model X rear spoiler "wing".

This car just destroyed the Goodwood Hillclimb record! It is legit!

Oh? Could you explain the T.50 or is that not road legal?

The issue isn't road legality, but whether it could function on a road. The T.50 also doesn't suck itself to the road, directly, the fan is not pumping a huge amount of air, it is just enough to allow a steeper diffuser angle under the car, to indirectly get a little bit more downforce. It isn't a situation where you would suck a bolt up into the fans or anything.

The McMurtry is directly sucking itself down with a ton of force, and they do suck up bolts, and have a filter in place to catch them so the fan isn't destroyed. Regardless, the intent of a road legal McMurtry is you drive it to the track, road legal, with the fan off. Turn the fan on at the race track.

That is an incredible feat of engineering. Impressive. Do wonder what would happen if it was raining while it drove? Might be a jet ski at that point. Still impressive tech though.
