No we are talking flywheel HP. (well the calculators are)
You are about right with the weight, except the series 5 TII weighed more than the FD; more around 3000. The S4 TII weighed around 2850 or so.
And anytime I talk about horsepower, I refer to wheel HP. Sorry, its a habit. If you look at my calculator, it uses wheel HP:

I've found it to be pretty accurate.
