Hi all,

Out of curiosity, what is the highest whp you guys have seen on n54 for 93 oct only fueling (no meth, no e-mix) with upgraded twins and/or single turbo? Any dyno graphs anybody can share? I understand e-mixes make more power, this question is for knowledge gathering around 93 only builds.

Any thoughts?

Thanks!

I think given how variable dynos are, the best metric would be best 60-130 dragy times.
Thanks for chiming in, I agree with you on 60-130 being a more reliable metric.

Full disclosure, there is a discussion around this in an n55 M2 forum, but not a ton of data outside of some dynos off various pure turbo offerings. Since n54 is so similar, and has many upgraded twins and big single turbo builds, I'm hoping to collect some more data points from 93 on larger more capable turbo setups.

A mate with Pure Stage 2 Hi-Flows on his N54 with Tesco 99RON makes about 490whp (not on a DynoJet) at around 24psi to 25psi.

Based off a speedo video I have of my car vs another car that dyno’d at 570whp I would say around 600whp is the limit on 93 with no overdrive kit or meth.

I’ve only ever been street tuned
