Some of the bhp is lost as heat as the tires flex and slip.

That's exacly why you have to have vehicle specific baseline readings. There are too many variables to do an dead-on accurate gains between two cars. The equation I posted are just approximations based on available data. We don't know for sure, for example, if the 350bhp is an accurate baseline @ the crank. Basically, we need at least three known values specific to the vehicle in question. For arguement sake, those values give you a rough idea.
....my brain hurts know.
Also, I think I just added to the stereotype about Asians being good at math.
