Figured you might want to see these numbers in case you've been wondering.

Just wondering if the 4s HP would show higher at the 8200 Rpm marl?

It looks like they did take it to the limiter at 8200, but I could be mistaken. I read somewhere, I believe in this automobile mag. article,that there is another dyno that would probably post higher numbers. I guess the one they used here wasn't the "most" accurate. So far though, this is the highest I've seen from a reputable company for the RS4. Not bad.
