I think we are moving in the same direction Chris.
I can't believe a v12 is only slightly quicker than the 924S. It would be great fun to race them!

What are the acceleration figures for both cars, though?

That v-12 generates much more torque, and can get up to speed faster. Ferrari would probably kill that P-car in a standing 1/4, 1/2 or mile... they would be more fun to road race with an "at speed" start around a curvy track.

From what I know, when it comes to racing the most accurate reflection of performance is neither top speed or 0-60 times... it is 0-60 in "x" number of ft. or a speed at a designtated (say 60 ft.) trap.... acceleration over distance rather than time.

I couldn't find the data I was looking for online, but my money's on the Ferrari...

I have to agree that the Ferarri would be faster, especially from a standing start.
As mentioned, torque and BHP will play the most signifigant parts in determining which car will perform the best. My money is on the Ferarri. Other things that you have to consider are the power-to-weight ratio and gearing. Again, I lean toward the Ferarri, as they have always been ultra-high-performance pieces of machinery, and the 924S is an entry- to mid-level driving machine. Big parts of this are the engine components; the Ferarri will most likely have a lighter flywheel, aiding in quicker acceleration, and lighter engine components which will allow the engine to spin up faster than would the 924S's engine. Plus, depending on the model of Ferarri, if the engine is located behind the driver/passenger, you don't have the added load of a driveshaft or torque tube to consider, which also affects acceleration.
My 2 cents...

Top end speed is as much a function of gearing as horsepower. The 924S will take a long time to reach 227 kph. By the time the 924S reaches 210 kph the 1972 Ferrari 365 GT4 2+2 would be an expensive little red Itilian blip on the horizion. Although I would always choose a Porsche over a Ferrari. When it comes to food or art I will choose Itilian, but when it comes to enginering I would definatly chose the Germans.

Top speed occurs when the available horsepower equals drag assuming the vehicle is on a level road.
