Is it true that the Saleen S7 creates enough downforce at high speeds to be driven upside-down?

perhaps someone could build a loop-de-loop

There is some type of modification that has to be done to make a plane be able to run upside down. I forget what exactly the modification involves.

Look up wet sump vs. dry sump oil systems.

Doesn't a dry sump still require the oil to flow to the bottom of the engine before being sucked out?

in a radial engine there is no up or down, no matter which way you point it theres an upside down cylinder. if it a 2 stroke it should run upside down out of the box without damage.

How would you test something like that in the real world? Do they have an upside-down track somewhere?

BTW, the new S7 Twin Turbo lists a 0-60MPH time of 2.8 secs. :shocked:

yes

F1 cars also do.

Its drag, but the normal force is so huge that it can corner in ways that look physically impossible. Truly an amazing car.

Right, but by the end of WWII the radial was seen only in the P-47, some of the earlier FW-190's, and the corsair among the top end performance fighters.

The mustang, the 190D's, the 109's, the spits, the tympests, the typhoons could all fly inverted. They used inlines.

Bingo, I've run my old standup jetski upside down and inside out, it does just fine but can only survive underwater for 4-5 seconds.

Glad someone caught it
