You are right, I forgot that they used the old block, and are dry sumped?
Hmm, I have driven quite a few modded Evos and Scoobs (Did I say stock? No, so don't try and put words in my mouth, ta), on a wet bumpy road, as specified, a 996 turbo won't see what way one has gone.
The 996 is a great car, don't get you panties in a knot over it. You pointed out, it is superior in such conditions to an Ultima (and many other very fast cars too....), I simply added that the 996 turbo is not king of the hill in such conditions, and it is not.
Horses for courses. I would have the 996 turbo over the Evo, and an Ultima over both, but each has its best areas.
