you would definately win mainly due to the fact the the twin turbos in our cars produce ridiculous amounts of torque at low rpms, allowing for breakneck accelations. I just test drove a brand new 2007 3.2 and it cant even get close to competing with my car. Stock it does 0-60 in like 6.7 whereas the b5 s4 does it in 5.9. The turbos also allow for much more modding to be done, with only a giac chip and downpipes you can run 0-60 in about 5 seconds flat. Remember that without torque horsepower doesnt matter.

 

As said it's not the peak HP, it's the power curve, it's the TORQUE that will let you pull him.

Our cars stock make 80% of the peak torque @ 1800 RPM's, & pretty much hold that for most of the power band.
