Nobody here would have a good reason for selectively increasing drag.

Except in an emergency. I just remembered when the brakes were out on The Big Bus: "Raise Flags of all Nations!"

Are they still injecting fuel into the exhaust at the turbo to increase their boost and give it some exhaust thrust as well? I am guessing not considering the news of the hybrid design

Back when I was 18 I really loved car racing. Got over it. by the time I was 30 I was a motorcycle racer and thought car racing was for wussies. When I turned 50 I was enamored with bicycle racing by the time I was 55 I was loving speed bike racing, trouble was I was driving for 2 days to race for an hour. I have figured it out, racing is all kind of just a waste except for the mental exercise of the designers and riders.

The nice thing about the testing on this list is that we actually get use out of what we drive.

F1 hasn't used turbos since 1988. They are currently using 2.4L naturally aspirated V8s, 18K RPM rev limiters (~750 HP). 2014 will be 1.6L turbocharged V6 engines, 15K RPM limiters. 2014 will also double KERS (hybrid) output from 80HP to 160HP.

Now that they have monitoring, it just makes cheating just that much more expensive and tricky. Makes driver choice that much more expensive and silly.

Taking some are from the grill would not be a problem I guess, but hey I'm just thinking some things up. I'm not an aero geek. Of course the effects should be at around highway speeds.
I bet it would, I had the idea of piping air from the sides to the wake since typical car has total crap for plan taper at the rear. The only problem is where are you going to route these huge tubes? Gotta have a passageway for the air, and there just isn't a whole lot of empty space in a car.

Given the volumes of air required and the pressures available you either hollow the vehicle out or increase the frontal area.

Here is an example that moves a modest amount of air a short distance:

No need for extra injectors. Now they simply shut off the spark or retard the timing and fuel enriched air goes straight out the exhaust, igniting on the way out to energise the diffuser. They even had off-throttle maps that kept the throttle open without driver input so that they could send hot exhaust straight over the diffuser while the driver was on the brakes.

This would have worked great as an anti-lag system for the new 2014 spec 1.6 liter V6 turbos, but they banned the sneaky off-throttle maps last season.
