Somehow I doubt that using stock horsepower in the formula, even if it's not a significant factor, would fly in ST.

I agree with Josh,
It's going to be hard to just have a formula based on either stock hp, or displacement and cam limits, because the intake manifold has to be oe along with the throttle body. The best option would be to take a page from GT, and spec a motor from each manufacturer, and allow it to be installed in any chassis from that manufacturer. Where ST differs from GT is running factory tubs and DOT radial tires.

Not stock HP - the ratio of stock displacement-specific HP of the model in question to the displacement-specific HP of the best car in the class. It would be a reference for volumetric efficiency which is the real determining factor if displacement is the first factor considered to establish weight. It's not my gig though so I've got no inherent interest in pushing an agenda beyond thinking that STL presents an opportunity to do things differently than GT, Prod, Touring, etc. in a substantial way.

Sorry, I guess I misunderstood ... what is "stock displacement-specific horsepower?"

He's talking about the ratio of stock hp to displacement, I initially misunderstood too. I still think it won't be a good predictor of potential. If you've got a 1.8liter four making 136 hp and a 1.9liter making 138. They're pretty close with specific hp, but one has a long convoluted intake manifold and the other doesn't so which is going to perform better to compression and cam bumps. Then if one has a fagile cast crank you can forget about any radial increase in rpm. So the real question should be where's the choke? Is it in the head, cams, exhaust,(which can be opend up in ST) or the intake manifold or throttle body (which can't).

But the ratio of stock hp to displacement would therefore use stock hp in the formula. That's what I assumed it was.
