An often misunderstood thing about turbo
and supercharged applications is that they
only work in the high RPM ranges, and rightly
so, as most of these applications are in high
performance high RPM sports cars.
The real truth about Forced Induction is that it
can be what you want it to be, you can make 5 PSI
boost in 15 feet from a stop sign, ask me how I
know

you can also set up the drive in a supercharger
to boost at lower RPM range, depending on the
unit, a positive displacement supercharger like a
Roots type will boost the same PSI from throttle
opening thru max engine RPM
A Paxton style, like the one mentioned boosts at
a variable rate, similar to a turbocharger, the boost
doubles with the square of the RPM that is is running
at, this is due to the non positive displacement nature
of this type of pump.
So this being said, a small well matched turbo will boost
at a low RPM, and yes even at low speeds in low range,
but it doesn't do a lot at 2000 RPM, which is just over
idle in a 1.6 engine, and a turbo is also not like a light
switch, there is a range of boost that can be controled with your right foot, more foot, more boost, up to the
preset waste gate max boost PSI
