Stroker build

[SYDAUSM3E92ZCP]

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.

with 292 duration cams what would you expect the 4.0L to rev to? Any significant impact on driveability with cams (in general)?

I'd still rev it to 8600. The 292 is not that big in the grand scheme of things.

I haven't uses the 292 on a 4.0 but with the stroker there are zero issues. On the stroker i wish i could get bigger cams

Interesting! My goal is 500hp (NA) to the crank—starting to research cams.

Whenever the tuning thing is worked out I bet we'll see good amounts of power with bimmerworld headers + karbonius intake +292 cams

That's what I'm hoping. Seems like a winning combination, and relatively inexpensive when compared to the cars you'll be competitive with on track...not to mention the driving experience.

The real challenge is the tuning. Tuners are too busy printing money selling the same cookie cutter tune they bought in a package and don't want to actually develop anything

I'm working on it

Keep me in the loop! Have you reached out to Alex @ Alpine at all? Off the top of my head he's the only reputable tuner that would seem willing enough to develop a more niche tune.

I haven't. I'm not sure Alex has a lot of time on his hands to be screwing around with this stuff.

RK did a good job with the stroker tune and the 292s, even with a CEL for trashed primary O2 sensors I got 465whp std on plain old 93 on a dynojet.
If I had a 4.0 with 292 cams I'd take it to RK to help develop a file but I have enough entertainment in my life between the stroker track car and the F80 CS track car.

I also tried a remote tune with Epic which was an incredibly frustrating waste of time. ESS was willing to try as well but I'm so far from either of them. They're both capable but are they willing to put in the work? Because the work isn't one morning of dyno runs.

I suspect the tuners in general will just sit around for another 5 years until one person puts in the work, then all of a sudden they will all be 'inspired' by that software and come out with 'versions' of the same file.

Today 292 cams/headers/Karbonius seems very niche, but give it time and it won't be. There is plenty of money running around the world and plenty of people who have money but still choose to run a S65 because of how wonderful it is, the last NA engine BMW will ever build. In the E46 cams 'were for idiots' until they weren't, and now people with CSL/Karbonius airboxes, cams and headers have a ton of power

It is really frustrating that a smart group of random people built the MSSFlasher for the S65 and fully decrypted the ECU yet no tuner is taking advantage of this.

Totally agree. I was one that was lucky enough to benefit from the renaissance in the S54 world. That car with even just an air box and super sprint stepped headers was pretty eye opening. Stock they put down 285-290ish. The cam’d car I rode in was putting 360whp to the ground with only some minor low RPM stumbles. That car/tune was not complete when I rode in it, however. Cams, exhaust and an air box was all it was. Plus, of course, the mod linking it all and making it work - the tune.

Can’t wait for the S65 revolution to begin :-)

Yeah..when I got into the E9x scene from E46 M3s I was surprised to see that more people aren't running intake, cams & headers. Can't wait for a tuner to come along and make an out of the box option. I remember reading old posts on M3forum (RIP) about putting hotter cams in an S54, and people said it was a waste of time. Now pretty much everyone going for power in an S54 throws cams in. Guess it's just a waiting game

Exactly

One guy has been talking about something that is truly a step change in the S65 but it's still early for results. The day I get them I'll make sure to spread the word. No reason why we can't have 420-430whp S65s just with bolt ons

[wyatth]

I eagerly await these developments!
And you and I have different definitions of “just bolt ons” haha!

Wow, sounds very exciting! Please keep the fam up to date with developments!

Same temp as before the stroker. Reaching 3/4 of the temp gauge is pretty normal when running slicks

Might explain why some run race spec 40 grade. This demo car sees around 117C (Racelogic CAN data) doing hot laps although on A052.
