Underbody evacuation downforce

One thing is that people here really like to have civilized conversations, you get much more help if you're respectful and talk civily.

I know what you're talking about, i have thought about it alot, in fact there's a thread that i started about them a while back, search for "fans for downforce". I see them as ideal for racing but not so for a street car, imagine the fuel economy, if you have electrical fans you need to use a beafier electrical system and the engine looses efficiency to them, also it happens at all speeds. If it's driven by a gasoline or otherwise motor, it will require gas and people will be filling up too often. especially now when gas prices are going up, the last thing people want is a car that takes more fuel to run.

One more problem is snow, if you want more traction in snow and you add fans for it, what does it suck up? Air, snow, sand, salt, all stuff that can clog airways and rust out tubes. if it's summer, what does it pick up? sand, rocks, dirt, and where does that go? directly in the car behind yous windshield. people are going to complain and the fans are going to be illegal on the streets. that's the reason the brabham sucker was banned from formula 1, it pelted other drivers with rocks, they complained, fans were banned.

I know of only one road car that had fans, the ferrari f50, it had fans going through the front hood. the problem with this car is that it sucked. well it didn't suck it was just so restricted with smog equipment and regulations that it couldn't perform to its potential. in fact the f40 was better than the f50.

In short, fans are great for racing but are far from ideal for road use. and for future reference, you'll get more help if you are civil, don't attack people, and know when to quite pushing the point.

actually, I can see one practical application for this, if you had it so it only ran in emergency situations, so if the abs turned on so would the fans and you could stop alot quicker without having the incresed tire wear and fuel consumption. But that's only if you could find a way to do the air ducting without sacrificing a whole bunch of space, as curtis mentioned.

in the fenders?

[beef_bourito]

what about getting it to the back? how would you carry it throughthe body, it would take up a bunch of room wherever it goes and you couldn't carry it through the fenders because then it would have to pass through the doors and i'm sure it would pose some safety problems and reduce the rigidity and make it easier for you to die in a t-bone crash.
