I don't think the dyno numbers are accurate.
Tom c63 was able to keep up with a Stage 2 Rpi M5.

The dyno # only showed the peak power, you have to look at the "area under the curve". From Tom's dyno, the torque came earlier and stay at the top past 6+k rpm.
So, when they raced against the stage2, especially from dig or 1st/2nd gear, C63 will be close or even ahead up to 120 or so, then M5 will start to pull. Torque/weight ratio win from the dig, and hp win the top speed. THe speed past 120 or so, it all about hp, while torque and weight have less contribution.
When eddie raced against Drew's E92 M3, eddie didn't pull past him until 120+.
I raced Joe's E63 before, and barely pull on him up to 120, but after 120, it totally different story. Against his E63 is heavier than C63. I believed they dyno about the same.

Thank you Grasshopper! I also feel that the M5 will pull after 120.
Maybe when i add headers and other mods i can hang!

Stock M5 vs stock C63....C63 rule.
M5 RPI stage2 vs C63 RPI stage2...C63 RPI stage2 still rule.
Looking forward for goodies from RPI for C63, cant wait.
Trust me, Uncle. Drop your C63 with Eloy and let him do his magic and you will save a lot of money (by spending somewhere else, then eventually come back to RPI...that what i did
)
