For me this mod wouldn’t be about more peak power. It’s about more time at peak. If I can make near peak power for 1000 rpms instead of like 300 rpms that will be a huge win.

Look at the dyno paying attention to the shape of the curve and look at the area under the dynos from 5000-7500. One has a big sharp peak with slopes, the other is like a table top. Even with the same peak power the table top would be better.

I firmly believe total area under the dyno matters more than a single high peak output, when both have the same peak number.

And where the rubber meats the road, when I’m running the car hard I’m only passing from 5500 rpms to 7500 rpms through each gear. That n54 dyno is especially sweet in that range.
