I am looking on line at local ones for sale and the ads are saying anywhere from 318-330hp. I did some research on line and sites are saying 250hp. Is this correct? Or are people just making up hp numbers for there stock S4's?

The 2000-2002 Audi S4 has a 2.7L V6 Biturbo engine which is rated at 250 HP. All manufacturer ratings are flywheel horsepower, which is the power at the engine, not at the wheels. A very popular modification to the S4 is replacing the chip in the ECU with another chip that allows more boost. Since the boost is computer controlled, this is a cheap way to get another 70-80 HP from the car. However, in the wrong hands this will accelerate the destruction of turbos, particularly in 2000-2001 models. 2001.5 models have an updated turbo system that is more durable.
IN any event, I would look for an unmodified S4 and if you want more power, upgrade the chip yourself with the understanding that if you thrash the car it will self destruct to the tune of $6000, which is the replacement cost of both turbochargers. Having the extra power for occasional use is fine but if you're drag racing or doing track events, it can accelerate the wear on the turbos. Most performance chips allow you to disable the extra boost for when you want to save fuel or drive hard, and let you enable the extra power for normal driving and passing, where the occasional hard burst of acceleration probably won't hurt anything. Of course, maintenance is very important, so be sure to buy only from someone who knows their car well and can prove that they've done all the required maintenance.

That's about right, the Audi S4 claimed horse power should be around 330 hp at the crank. The 2001, if I remember right, is a V-6 with a turbo.
The site you researched is probably horsepower at the wheel. You normally lose about 20% of power from the crank to the wheel pending on which Dyno was used to measure the horsepower at the wheel.

The first S4 came with a V6 twin turbo, the same engine used in some models of A6, with 250 hp. They change the motor on more recent versions using a 4.2 litters V8.
What you found is correct.

It's about 225-240 at the wheels, and about 275 at the crank. Check out www.audiworld.com. It's a free public forum, and there is a ton of knowledge there.
