Thanks for the clarification...why is it that everytime I see brake HP (usually euro magazines) it lists 343 hp. And most us magazines list 330. I'm guessing that the euro SAE HP calculation is what brake hp is based off of, and the US SAE HP calculation is what is used for us magazines.
I guess if I really wanted to know I could read all this
