I have a question... is it believed that building for high HP means having a narrow, peaky, torque curve? Because, that is simply not true. I can show you dyno sheets for 9000 rpm race engines that are flat over a 3000+ rpm spread. Every performance engine I've ever owned was developed to have the widest, flattest, torque curve possible.

The real question being discussed in this thread is, what is the best rpm range for this application? Once the rpm range has been determined, saying, "tune for a big flat torque curve" is stating the obvious.

Of the 4 engines I've had in my Cobras, I've always built them for max power in the 3-6000 rpm range... because I drove them on the street as well as the track. An frankly, the power we made in that rpm range was probably more than my average skills could use anyway.
