Do you know a cold blown from a hot blown diffuser?

Still in the dark? Read this easy to digest explantion of blown diffusers on Eurosport.
I certainly found it helpful in filling in my knowledge gaps, which was pretty much all of it.

Thanks for posting that John, a very informative article. 

Reading that makes you appreciate how innovative F1 engineers and designers really are, and the lengths they go to to make that cars quicker. One word, Awesome!

In saying that, if Ferrari can't sort it out I hope they ban it.

I can't remember what car they were testing on Top Gear, but that article reminded me of it - it had a trick that when you changed gears it shot fuel into the exhaust to soften the change and give it a funny noise.  Very cool. 

Interesting stuff John.  I had no idea they were doing that.

I think the car you are thinking of was the Prodrive P2 concept car. It had an anti-lag system to keep the turbo on song, like a WRC car.

Unreal! I love the idea of a hot diffuser, I never realized that they weren't burning the gasses as they went through the engine

Great Find

The FIA is just reaching here, stretching their interpretation of the aero rule to eliminate something they feel wastes fuel and will cost the small teams too much money to develop. Allowing a ground effects type of design would reduce the effectiveness of blown diffusers, but now apparently they are not going to allow that either. F1 has way too much down force and the current rules concentrate it at the ends of the car. When they get right behind another car the front wing loses air due to turbulence from the leading car, while the back keeps right on working. Result, understeer.
