S54 Dyno Database

[2004LSB]

^^^ Thanx for posting! Would you mind providing some details of the build in the dyno thread please—thanx!

More details can be found here:

https://nam3forum.com/forums/forum/m...r-yuge-numbers

Basically I went from the following:

1. Stock baseline run
2. Karbonius CSL carbon fiber intake, snorkel, Euro headers & cats, PCS Tuning (canned tune)
3. Karbonius CSL carbon fiber intake, snorkel, full Supersprint oversized system (stepped headers, HJS race cats, resonated twin pipe, street muffler), Mishimoto electric fan conversion, Paul Claude Smith's custom dyno tune & 91 octane pump gas on stock cams 👍

Thank you PCS Tuning! Will start a dedicated thread for more details!

Appreciate the commentary. It would have been reassuring to see Kassel raise a hand and say something looks off; he's more qualified than many others. In the video I linked, it was actually the guy filming who did this but nothing more was said on the matter, and we can see how that video was titled for upload to YT. At the end of the day, the allure of big results and YT clicks will win and this a good example of such.

Ya, I'm not sure how Kassel left it w/the customer, and we don't know what may or may not have been edited out of the conversation in the vid? Jim and Matt are both solid ppl, and I would choose not to believe that they would intentionally mislead the customer. I think we can let this rest here (at this point) knowing that his car isn't the "fastest stock S54"-lol.

Hmmm, I've never really seen any overly optimistic figures from Kassel...usually their numbers tend to be a bit lower than most Dynojets. Anyway, sooo...apparently Kassel's dyno developed an issue (computer had a board go up), and so they had to get new software. They are still dialing it in, and they estimated that it was somewhere around 20% high for that particular dyno session...which would bring the number down to a more realistic figure somewhere in the low 290's. Not sure if they informed the owner or not of the possible discrepancy, or if the guy just wanted to make a sensational YouTube vid-lol.

Its not the first time recently that I've seen some strong numbers from Kassel. Here is a clip where some figures are reported and being discussed on an S54 with stock cams (I set the clip to start around 6:25). I'd be interested in some analysis from those that are well versed in reporting numbers. At first pass, you think "really, 275 - 280 ft lbs?"

yeah they have themselves a good ole random number generator.

Dyno's are a tuning tool blah blah blah but i would advise anyone interested in seeing what their car makes to find a dynojet, as that seems to be the only consistent way remaining short of the black strip. Every tuner says their dyno is a heartbreaker and reads low they must goto the same school....lol

These other brand are dynos are good for tuning but operators can mess with a bunch of corrections to make them self look like gods when they are all just keyboard jockeys and there just isn't much to mess with to change the WOT output. There is no magic tuning where they magically unlock some previously undiscovered parameter. i mean a number of tuners or their customers have said they have calibrated their dynos to read same as a dynojet lol so they are just messing with corrections which makes numbers look better. I'm sure some aren't doing it to be deceitful.

Torque numbers are easily frigged if the rpm axis is wrong which it seems to be all too often on most brand dynos.

everyone knows a stock S54 with tune is not making anywhere near 350rwhp legit

Yep, we know...just had to confirm through someone first though

The owner is posting it on Instagram as WHP gains. That’s what made me wonder.

Yep, that's why I had to check it out. Not to be a dik, but guy is obviously clueless if he thinks his "stock" M3 is making that much to the tire-lol. (Hopefully he's not on here.) See comment below for an explanation.

EDIT: Just to add, the first run on the dyno measured 291 (you can briefly see it/hear it out of the owner's mouth)...then something changed and it bumped up to 351. This just confirms the low 290's I mentioned above. Something either glitched out in the dyno software or they were still trying to recalibrate.

Kassel has a Mustang dyno that normally reads about 3-5% lower than most Dynojets...assuming that nothing was changed for that particular run.

I’m waiting to hear from someone, but I’m calling BS on this until I can confirm-lol

I saw a preview for this video on instagram. Im no dyno expert by any means so please forgive me in advance. Does Kassels dyno measure in wheel horsepower or crank?

My E46 M3 Finally Hits The Dyno!! (Fastest Stock S54?) - YouTube

[RedM3/4]

Thanks! I've been trying to decide between the Eventuri and CSL. I know there are other factors, but this analysis and ease of install, pretty sure I'm going Eventuri.

ADS
------------------------------------------

- Euro 2004 E46 M3
- Milltek Center Section
- RM Motors Decat
- Stock Rear Box
- Eventuri with air temp bung
- AEM ECU


Then with more tweaking:



So, not quite the result I was expecting with the airbox, however I did pick up more midrange, and chunk up top along with more torque from 3.5K onwards.

Overall, it seems that the stock plenum is VERY well designed and adding CSL style air boxes don't always mean more power!

[stash1]

Stan,

- Karbonius box
- Intake and exhaust performance camshafts
- DynaMite is the Dyno I used which shows exact as the Dyno-Jet I use all of the time.
I have done/tuned at least 15+ set ups at this specific DynaMite and next day at Jery's Dyno-Jet
to check and the difference is 2-3hp which is subject to weather temps, air density from the night before
and next day morning etc.I have over $2k in renting dyno time, tuning and comparing Dynos
with same car, my preferred dyno is Dyno-Jet and why I tune on the DynaMite and next
day I am Dyno-Jet.
- Headers are modified
- I forgot to mention I have 52m ITB's which ehhh...

HP ECU converted to 1 Bar MAP/TPS which is what is used on CSL-S54 and very common on
other engines.

Stan brother, I worked hard to get this number....

I have another S54 engine on the Stand and I told my other customer I just need little money
and I am confident a hair under 360rwhp on 91 Cali gas Dyno-Jet number.

See, not everything is HP, my target is to push the TQ hi as well...the ingredients must be proper
otherwise the results are not there.

Anri

Hey Anri, yeah, I was wondering what happened to you there for a couple of wks, and now I know...you’ve been chained to that dyno all this time-lol. Curves look great brother, and again, very nice results on piss water! Which cams did you go with, and what’s the entire exhaust look like?

[Anri]

Who did your tune?

Hi,

I work with a local tuner and we did the tune together.

Regards,
Anri
