Well this is a technique that many many rally drivers use as well as Hurley
Haywood and Hans Stuck (both of whom I have met on numerous occasions, Hans
is a family friend) used in the Audi's from the Trans Am and IMSA series, so
it's not just me you are laughing at.
The boost is kept up because at WOT my car develops over 1bar of boost
anywhere over about 2500rpm. If I'm entering a corner where I can stay in
the same gear and keep the rev's over about 4,000rpm then I like to left
foot brake and hold the boost. It's especially good in high speed chicanes
where I would just need to maintain speed for a short time rather then gain
velocity.
