Danny what dyno was this tested on? Did you have it done independently or was it done by RK tunes?

The dyno was at RK tunes.

Halfway through the track season I got it dyno'd at an independent dynojet, 465whp STD with a 10:1 AFR and a O2 sensor check engine light.
I bring the E92 and/or CS with me to these events to get a good baseline and the E92 read the typical 12/13 AFR. The CS read 14.7AFR.

In the original dyno the E90 read 12/13 AFR as you would expect, I assume the whp delta is due to o2 sensor

Anyway, sometime this season I'll dynojet it again.

...or it could be that Jordan's dyno is a little happy? I've seen/heard of a few guys that dyno'd elsewhere on DJ's and recorded lower numbers. I've seen some pretty wonky torque figures for S54's come off of his dyno too. SAE is typically about 2.6% lower (77* correction factor vs. 60*), so that would make it around 453 HP...still crazy power! Get that O2 changed and see if it picks up any power!

Perfectly possible, but I still expect to be higher than 465whp on a dynojet later this year
I should have dyno'd on a dynojet soon after getting it tuned, but the build was late for the track season and it was pure mayhem.

Even 465whp STD is a good chunk more than the Alekshop car so even if that were it I'd still be pretty happy.

Yessir, killer build/numbers for sure! I need to get my S54 to your engine builder-lol.

Now I'm dying to try 292 cams on the E92 (4.0L) with Bimmerworld headers and the Karbonius intake. I bet there's around 420whp in that combination which would feel pretty wild

As tuning continues to get refined for the S65 I expect builds will gain power. RK has done a great job for sure.
