Fun fact, car was rated at 250/258 at the crank when it was new, and it dynoed at 280/316 with the mods I have, and I'm still seeing a higher percentage improvement over my civic which wasn't modified beyond the engine swap. I've yet to hypermile the car on the highway, though I am seeing about 20mpg in the city, which is a 33% improvement over the EPA rating of 15 for the 6-spd. I do all my calculations with a nifty little app on my droid, tracks mileage stats and cost per day cost per dollar figures. It costs me about $4.50 a day, or $0.166/mile to drive the S around town.

Not too shabby for a cement salesman's saloon.
