Hi ,
I can't give a number for a ground effect car , as each car is very
different. FYI , a wing can produce lots of downforce at 50mph.
Each wing has a different Lift/Drag Cofficient, but here are some
popular wing designs and the amount of lift [downforce] they produce.
formula here is lift, lb = .00256xClxSxV2 Cl is lift cf, S= airfoil area
in sq ft, V = speed in mph; for all you math heads.
A clark Y wing @ 32sq ft = 174 lb at -10 deg of attack and 256 lb at15 deg
THIS IS WITHOUT ANY FLAPS OR GURNEY LIPS.
a 23012 wing with a slotted flap run at 40 deg of attack has a Cl of 2.7
or 553 lb of force.
This is a lot of extra grip on a 1200lb modified car.
This is all at 50mph.
