In ideal circumstances. In less than ideal circumstances you go from roll oversteer to power on oversteer to a tree.
It's the same reason why me running a 911 3.3 Turbo from the mid to late 80s is a very bad idea indeed. If you brake in a corner, you get oversteer. Shoot if you lift off, you get oversteer. If you apply too much power, you get a delayed oversteery action. It's nice and stable as the turbochargers spool up of course. :)
All of the above assumes you were going in too hard or trying to come out too hard. And I don't see the point in buying a 911 if you're not going to try this some of the time.
Solution?
Boxster. Meh.
