That's more logical and thank you for the thoughtful reply. It all comes down to how you drive which has to do with the driver not the engine under the hood. The initial implication that a v8 swap required such and such mods over the hot rod 4cyl is what we've just debunked. The weight similarities could nearly be eliminated with a battery relocation or smaller unit. The difference is so small that between drivers you might see more of a difference (driver Bob weighing in at 240lbs after a healthy breakfast, driver Tim weighing in at 160lbs after visiting the port-o-let).

I had a 1.8L 4cyl GTI in high school that I cut my teeth on that is similar mass to a 944 (~2600lbs). I could get those brakes glowing and smoking on the back roads hauling ass. I didn't need an increase in HP to require bigger brakes I only needed to drive like a maniac on public roads. It took work and recklessness to get those brakes hot.

"I have a faster car so I'm going to automatically drive faster." We're not in highschool anymore (well, maybe a few of us literally are) so hopefully we know better than to run a Porsche to the mechanical limits of the brakes on public roads. The brakes these cars come with are not 9.1" solid rotors with miniature drum brakes in the back like my similar weight GTi example above. These Porsche cars come with decent brakes relative to other makes. With these better, OEM Porsche brakes, it will take far more aggressive and prolonged driving than the canyon/gulf runs and it won't matter which engine you have if the power output and weight is similar.
