Maybe I better elaborate on why dissed the PG for performance driving. PG
cars are fine for everyday driving, with no special requirements. That is
the reason Automatics are so commonplace in every car line these days. If
there are NO special requirements, the low-tech automatic is fine. And for
some very special requirements, the Automatic can be fine as well. In Drag
racing, the only thing that matters is launch off the line and pulling power.
Throttle response, strangely, doesn't matter much, you are almost always at
full throttle. In some autocross classes, where the car has an abundance
of power and great brakes, a driver can learn left-foot braking and overcome
the inherent drawbacks of an automatic, poor throttle response from off
throttle and limited - or no - engine braking. But in true performance
driving, where the throttle is used to position the car and load or unload the
suspension, the low-tech automatic fails. Only the stick/clutch systems
provide the driver with the instant feedback and response needed to perform,
consistently, right at the limit. If you try to use the throttle on a PG
equipped car to help position the car in the middle of a corner, you will be
sorely disappointed. Even the most learned automatics, ones that hold off
upshifts if in a corner, match RPMs on downshifts, cannot match the lap times
of the properly driven stick - over the long haul. Now, I must admit, there
is a new breed of automatic, these twin disc clutch systems which can shift
as fast and as sure as a clutch (I am still excluding F1 technology and
other upper echelon racing here -that is a whole other world). But those
systems are not available to us low-tech Corvair folks. We can barely get the
PG to shift smoothly and not shed E-clips behind our backs. Some of the
drag-racing tricks, such as high stall converters and extra clutch packs for
high load, have been adapted to the Corvair PG, but those put the trans in
an even more specialized, highly strung position. That same equivalent is
there for the sticks, close- ratio transmissions and lightened clutches and
flywheels will make that car a pain to drive - except in a very specialized
activity. I actually agree with Mark, that the best use for the automatic
will be to assure that he will still be able to drive his Corvair, even when
his clutch actuation days are over. And if you want to drag-race
consistently, check with Ken Arnold and Billy Bruce, their PG equipped Vairs can run
fast all day.
Enjoy!
