many thanks, local salesman didn't seem to be quite sure. VW/Audi
seem to be using the turbocharger and the 'lag' is annoying making me think
that the engine needs a tune up. I've never heard of a car using both, do
any come to mind?

Turbochargers have the capability to generate a lot more boost and
ultimately make more power than superchargers. It's also a lot easier
to fit an intercooler to a turbocharger or a centrifugal supercharger.
The drawback to turbos is that they take a moment to "spool up" when
you press the throttle, and if the engine doesn't have enough torque
on its own before the turbocharger spools up, you can get a pretty
If I were building a performance engine from the ground up, I'd make
it large enough that it had enough torque even without forced
induction, and then I'd also put a turbocharger on it for more power.
For smaller production engines, superchargers are nice because they
generate boost constantly, with no "lag" when you apply the throttle.

I can think of two straight off - one version of the Lancia Delta Integrale,
and a current production VW 1.4l, but I can't remember what they call it.
Makes something like 175 hp from 1.4l with quite good fuel mileage, but the
potential repair costs boggle the mind!
Kevin, you are absolutely correct ... was in germany over summer and
remember reading about the new Golf 'TSI' that uses a 1.4 l engine and has
twin chargers - turbo and super - along with 'direct injection (however that
is different from the fuel injection already in place) .... looks very
