The second part of that assumption is doing all the work. There are plenty of modifications to the A engine that substantially increase efficiency and do not substantially increase heat output. The original question was, why does a heavy-duty radiator "make all the difference," and I don't agree that you can address that by saying "more HP = more heat."

If the argument had been something like "well, when you modify the engine you tend to drive it more aggressively, which increases the load on the cooling system, and the original radiators often aren't in top condition, so installing a beefier radiator is a good safety precaution," I don't have a problem with that argument. But it doesn't, like, proceed irrevocably from the laws of thermodynamics.
