Sorry i had to use this post for my question (couldn't be bothered to make a new post)
I also makes sketches during my spare time, this is one of them.
My proportions of size of the diffuser should be correct,anyways is it legal/illegal to have a "scoop" originating from the of the floor and extending above the central part of the diffuser?. Is this effective in terms of downforce and is the drag >.
blue= air releasing over the central part of diffuser this air might be coming from the upper floor,exhaust, over/around sides of engine cover.
red is the air originate from the "scoop"
green is the from the underfloor.
In the central part of diffuser the majority of air is from the scoop releasing on the 2ns deck above the central section, and remaining air escapes around the scoop releasing at the central part of diffuser.
I don't have engineering/aero background so don't be to harsh, i just like creating conceptual ideas. btw used goggle sketchup.
