Would F1 blown diffuser work on road cars?

As some here might know Renault (other teams as well, but Renault seems to have mastered it)  introduced a diffuser where the engine keeps blowing hot air into the diffuer by keeping the throttle  open (up to 90%) even if the driver goes off the pedal, thereby increasing the downforce at low speeds. The timing gets retarded completely so while the engine produces plenty of hot air there is no torque. Would that also work on street cars, or are even cars like a 911 GT3 RS to much of a compromise for this to work?

Well, sure it would 'work', in the sense that it would function. It's possible.

Is it feasible? Probably not. F1 engines are built for all-out power; they don't last long. They're certainly nowhere near as durable as a typical car engine. Keeping the engine at 90% throttle all the time would destroy an engine in no time.

Besides, why would you bother on a typical road car? Normal road-going cars don't have to accelerate around a corner at >1 g. If you did so with any regularity you would probably lose your licence.

It would improve the N?rburgring lap time.  :lol:

Hmmm, a road car with an (soon to be banned) F1-style blown diffuser?

Sounds like the Top Gear guys should build one to see if it would work.  After all, how hard can it be?  :lol:

Probably wouldn't be that effective as a diffusers effectiveness is severly limited by street car ride heights and speeds
