True Power Figures

ChrisSTR · 09-14-2019, 04:13 PM

From what I came to understand, mother BMW gave M4 more power that it says. From a research that I've done (mainly for...academic purposes), we're talking about 20hp or more but the information is kinda confusing. So, now that the production cycle is coming to an end and the knowledge as a community is richer, in a nutshell, what dyno runs say? And last, do we have a dyno with 100oct fuel?

Don't think 100 octane fuel will give you any gains without a tune for it.

The M4 does not "make more power than it says".

You need to get familiar with power rating standards to understand why the M4 makes more power on chassis dyno than expected.
