Like Cliff, I am really not a fan of the XE’s cams either, but sometimes (like right now) that may the best of what’s available.

These threads often end up focusing on peak HP and/or peak torque, which makes sense to me for a race car.

But as these two comments suggest, not everyone wants to drive a race car.

What chart and/or metric is the best predictor of "street manners"?

Would the answer be a comparison of the torque curves or is it more about "area under a curve"? I'm pretty sure it isn't peak HP nor peak torque... but more about what happens at low rpm up to peak and where the peaks happen.

A long long long time ago, I had a 2-stroke 100cc Hodaka Super Rat. My room-mate had a 4-stroke Kawasaki 175. The Hodaka was useless at low rpm and was basically either "on or off". The Kawasaki had low end grunt and what I would call better "street manners".

I also owned a couple VW Jettas that were fun to drive. Granted there was no power, but the torque curves were so flat you often couldn't tell what gear you were in. To me, this is "street manners".

Maybe my definition is wrong... but I'm curious what others think "street manners" means and whether a simulation like Stan's can predict it?
