S54 Dyno Database

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!

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.

Anri

Hey Anri, very nice results for a budget build! Is this on a DJ? Sooo, no cams? Which airbox is that?

Stash,

I know its not an E46M3 but please allow me to share what I achieved
with the S54 Love.

- Intake and Exhaust camshafts.
- CSL Box
- "Budget" headers they are not really equal length....(measured them)
- Crappy California 91 Octane gas.

My concentration on the power was to dial the Mid-Range torque were we
need the "kick"

The camshaft timing brought the pick hp around 7650-ish so that it comes
little earlier and keeps it flat to about 8150rpm and rev limiter is 8200+/- rpm.

There is another 5rwhp with little tweak but no need to push the ticket on
91 Cali gas..

Chilled passes like 3-4mins between runs
353.8 rwhp
265.1 rwtq

Hot passes one after each other.
348.5 rwhp.
259.1 rwtq

Regards,
Anri

Evolve has been responsive but the tune is a PIA. Always new versions of the tuner software and the biggest is I can’t hook up to ISTA because the tune is locked or something.

Yeah, planning on going with Paul.

Ya, sometimes it's worth taking the loss and moving on. Similar situation to those that had TTFS.

[bigjae46]

Jae, lose the current Evolve tune, get an airbox and contact Paul

Figured as much because of the headers.

In my experience, catless headers shouldn't lean it out as much as that - either way, correct tuning should lift that whole curve nicely

[paulclaude]

IMO it looks partly real it is present in the baseline albeit worse and there are some small dips associated. It'd need to be a pretty amateur tailpipe setup to be contaminating the reading

I would agree it is real - you can see similar in graphs above. A lot of the problem when trying to dial out AFR swings at lower RPMs is the tailpipe wideband feedback tends to have some delay due to the slower exhaust gas speeds, so indicated RPM on the graph tends to be a little out of whack. That brings in a little trial and error as to what map RPM axis value to target, so along with dyno time constraints, it's often hard to clean everything up as you would want it, especially when primary focus is normally on that top figure

[bigjae46]

That engine is running far too lean overall, and the power loss at 5-5.5k looks to be due to the even leaner spot, which will most likely be triggering knock and resulting ignition reduction. Needs more fuel everywhere, for starters
