Different way to increase downforce your opionons on my idea

So I'm sure you guys all heard of sucker cars. Using a fan to suck the air from under to car to cause the air to become more negative , which caused more down force. now here is where my ideas comes in at. What would happen if we would panel the bottom of the car I know nothing new there. Then install the air intake inlet under the car. The intake will suck in the air from under the car, causing more downforce and if the car has force induction it would then increase downforce. So more power more downforce.

I can see what you are thinking of. But yo want your air intake to be in a high pressure area as much as possible, hence the ram air set ups on F1 and indy cars. The minute amount of pressure that might pull from under the car wouldn't out weigh the loss of power from a cleaner air source I would think.

that is very true. That totally slipped my mind when I was thinking of the idea haha. Thank you for your help!!

There's also the upside of porting your motor from road debris..

The other disadvantage of sucking air from below the car is the air down there is HOT. On a hot day, the air temperature at the surface of the road is 10's of degrees hotter than just a foot above it.

Smokey Yunick would have said that hot air could be a good thing..

Came in here to talk about hot air and debris, was beaten. But there's also the fact that your intake suction is nothing compared to a sucker fan to consider. And then the safety issues inherent to sucker cars...

i also think the intake wouldnt create enough of a vacuum to make any noticeable downforce

The sucker Vette pulled about 10,000 CFMs, and only had 1 successful autocross run.

The Chapparal 2J was much more CFMs.

Your engine does not intake anywhere near that.

Debris is a big deal. I worked the track the day the sucker Vette ran. We were showered with bits of gravel and trash every time the car passed. I wouldn't want that crap in my engine.

Heat has already been mentioned.

But the biggest issue is the lack of consistency. You would gain the most downforce on hard acceleration- straightaways, right when you don't need downforce. You would loose downforce (and therefore traction) as you let off the gas and feathered the throttle through turns, right when you need the most downforce.

Not gonna work.

But score a few points for creative outside-the-box thinking.

Why would you want your engine intake in a low pressure area ?
