i think heng and tofu brought up an example of the lancia dat
has this set up.
but it is quite unlikely that u'll find a production or aftermarket
tuned car using a similar set up. reason being, driveablity.
sure, it'd be great to have the low end response of an SC and the
high end kick of a TC, but mating them both requires great
technical competency and a deep wallet. and at the end of it, u are
not gonna get more hps den simply going TC, or more torque 4 dat
matter from simply getting an SC. and it is likely dat when it all
adds up, u really have a car thats neither here nor there
thats
a) too complicated/equipment bogged to drive on the streets (an SC
would do nicely already),
b) too complicated to track (since u are using high rpms most of
the time, a TC will do nicely), and
c) too complicated to drag (coz u juz need 2 launch the car at
higher rpms for a bigger turbo 2 get around the problem of
lag).
