Their are a few cases were power shifts are good to go -
1. Rental Cars
2. Looking cool during the violent one time test of your engine and
driveline.
From experience it might work on the drag strip with a car set up for
it doing it.
From my personal experience in NON RENTAL CARS
1. Broken spider gears D44
2. Twisted pinion off D44
3. Broken U-Joints
4. Sideways into a parked car
5. Broken off shifter handle
6. Broken engine mount
7. Destroyed engine thrust bearing
8. Cracked/removed friction material on clutch disk
And so on.
Never broke a gear box, but plenty of time for that. But now that I'm
older and somewhat wiser (only a little) I now reserve the speed
shifting for rental cars when manuals trans are available. If you want
to go fast for drag racing just get an automatic something ;)
IMO it's all around it bad for everything although wickedly fun when
done correctly.
