Ok, let's get the record straight on this one. Acceleration numbers are a result of torque, not horsepower. Horsepower is a figure of sustained power, or what it takes for your car to maintain the speed that the torque got it to. That being said, let's reenter the numbers:

WRX- 217lb/ft @4000rpm

SpecV- 180lb/

3085 lbs divided by 217lb/ft = 14.2 lbs per lb/ft of torque

2548 lbs divided by 180lb/ft = 14.1 lbs per lb/ft of torque

The specV actually weighs 2548 lbs, not 2708.

In the end, this means that in power numbers, the SpecV has the advantage by about 90 lbs overall. The actual final numbers on the torque to weight breakdown leave about .05 lbs per foot (14.21 versus 14.16). Again, that leaves them pretty evenly matched, with the specV taking the slight advantage.

Finally, we must consider torque curve. We must assume that at interstate speeds like the ones described here, both vehicles were roughly between 3000 and 4000 rpm. If you have ever seen dynoed torque curves for the two cars in question, you know that the specV has a marvellously flat one, meaning that it makes rather consistent power in this range and below it. The WRX, on the other hand, is a peaky motor, and so in this range, is still climbing dramatically as it comes on boost. As an experiment, run your SpecV against the Sooby up a hill at lower speeds and see what happens. The V has it every time.

The trap speeds, by the way, are rather misleading. Understand first that the WRX reaches 60 mph much faster, leaving it only looking for 34 or 35 mph for the last 8 or 9 seconds of the run. That, my friends, has everything to do with grip. The X launches a whole lot harder, so it has less work to do rowing the gears. It's a good thing, too, because it lacks the potential to do the work in second and third that the Nissan has.

Sorry for ranting. I just had to say it.
