Make that a race through 20 miles of twisties to your favorite lunch spot, then tell the windsor guy what you want and he'll have the sandwich waiting when you get there.
That's how I assess getting from point A to point B faster

Respectfully, I have to disagree with these statements. For proof just look at CSX3170. He is running a high hp big block that's putting out well over 600 rwhp, pulls 1.45 G's in the corners, accelerates up to 1.2 G's. Pretty amazing stats and balanced performance in a chassis that's not as stiff as most of our Replica's (although his is extremely well sorted). It's all in the set-up.
I'm very fortunate because I can vary my hp setting over a 200 rwhp/tq range by simply turning a dial to control boost levels. This allows me to objectively see where traction thresholds are for any particular day (warm vs cold air temps, road surface quality, etc), and a G-tech RR meter to measure acceleration and handling parameters. Believe me when I say that greater than 450 rwhp/tq on the street is usable. If it wasn't, I would have gotten bored and sold my car years ago. A 40-100 mph roll at around 575 rwhp on an 80 degree day is Nirvana.
