Dang it, AJ, I was expecting an insult or wisecrack from you!   You disappointed me, man!   Not only have I learned a few things from your posts but I also laugh out loud at some of your comments.   :)

Sorry to disappoint....i find it hard to say rude things to people that say sensible things

This thread is killing me. It's not called "Brake boosting" it's called "Left foot Braking" there was a video about the Audi Quattro years ago about how it's done and how the Audi dominated because of it. I'll try and find and post a link . If anyone can find it, please post a link. It does work I have tried it. It also works on front wheel only cars. with or without a turbo. No so much for power but for handling.

So in short, if you come flying up to a turn and you hit the brakes. This transfers the weight to the front of the car/truck. Stay on the brakes and apply full throttle. You are going to use your brake as to accelerate by lifting. In a turbo car/truck your boost is already built up due to full throttle. When you straighten out and fully release the brake you will shoot forward due to full boost already being built up.

This thread is getting down right weird, now I'm agreeing with AJ? WFT!? Semantics, call it what you like its the same damn thing. I come from rice we call it brake boosting. And the point of the thread was for me "new to this platform" to find out of the car is actually building boost while at a standstill, holding the brake and revving the engine to 2-2.2k. Apparently little if any.

In the Mazda we could tune for flat foot shifting "maybe Audi has a name for that too" which would float "my word" the rpms so they would not drop below 5k when keeping the gas to the floor but at the same time not allow it to hit the rev limiter. This of course kept the boost up so once you were in the next gear and let the clutch out you were on your f'in way. Glad I don't have to worry about that anymore, I am far from a professional drive :)

You young little whipper snappers can call it what ever you want. But look at the date of the video and you will see it was probably made when you were still in diapers. Therefore the term left foot braking was used first. :-p...

Watch all of the videos. It's really interesting.

PS don't kill yourself trying this in the corners. It can be tricky at first.

When I was a youngster, we called it "power braking."   Later on, it seemed that the term became "brake torquing."   I think most car mags like C&D use that term.  With more and more turbo cars, apparently the term is now "brake boosting."   When I am at the track, I have heard people use all 3 of these terms, depending upon their age and what they are driving.

Old Fart ;) must be a Cali thing, they do everything backwards there haha. I can assure you I was born before 1990! Seems the term took hold as more turbo cars hit the road/track. Interesting video though, thanks.
