You don't even need to respond to that, it's like self-ownage. BTW three Engine Tech mods agree: you're a dumbass!

 

diffusers have nothing to do with downforce idiot

 

You're right. They have everything to do with reducing lift.

 

no they have everything to do with smooth airflow underneath the car. kind of like those drag racing rear bumpers with holes in them that let the air escape. on a stock bumper it kind of scoops air inderneath creating some drag.

 

wow, its amazing how much incorrect information comes out when everyone thinks they understand thermal dynamics.

 

Yes, it promotes smooth airflow under the car. Now think about this for a second... if the air isn't going in a straight line, where is it going?

 

True. A "splitter" is something which catches the air and creates downforce like a wing does. Note the air foil which is designed to create downforce.



Downforce pushes down on the car. Does it reduce lift? No. Does it counterract the effect of lift somewhat? Yes. Does it suck you to the ground? No, it pushes you to the ground.

Again, downforce pushes down on the top of the car, lift pushes up on the bottom of the car. They are opposite forces. Adding downforce does not reduce lift, it works against lift.

A diffuser does in fact reduce lift. If there is laminar flow of air under the car as opposed to turbulent flow plus less total air being directed under the car, you will have less lift. "More aerodynamic" means you have a less turbulent flow of fluid (in this case air) around the object (a.k.a. the car).

True. Just remember that if you have an aerodynamic aid which is not intended to affect downforce, it is intended to affect lift.

A true diffuser such as at the rear of Ferraris and other cars which spend significant time in the wind tunnel, is designed to create an area of negative lift at the rear of the car. In this case, the car is actually "sucked" down to the pavement by the forces underneath it, rather than pushed down by a wing creating downforce.

Have we had enough fun nitpicking yet?

 

whats your degree in madtown?
