S54 Dyno Database

8500 and still climbing is impressive for a stock long block S54, let alone AWD.

How did you do the oil pan? M54 pan with an S54 pump and custom pickup?

M54 pan yes. The internal workings I am not sure to be honest as I was not the one who did the swap. The swap was done in 2019 and the car exchanged a few owners since then. I've owned it since 2024 and been bringing it back to proper spec (there was a LOT wrong with this 230k chassis) since.

Posting it here as I was comparing my results today with other S54s

Dyno'd my E83 X3 with an S54: 343awhp & 250ft-lbs of torque (Dynojet)

- AWD S54 swap mated to the E83 6-spd transmission
- Turner Motorsport CF Intake
- Kassel Performance CSL MAP Conversion
- Megan Racing Headers
- Gutted cats
- Rogue Engineering "El Diablo" rear muffler
- Tune by Kassel Performance

[bigjae46]

Mods are:
- Epic Alpha N Tune
-Evolve Airbox
-Megan Headers
-Stock Section 1
- Bimmerworld Street Track 3.5"

Stock pulleys, tropical E36 M3 Clutch Fan

The car is wanting to pull timing after 7k rpm, Randy was saying the IATs were pretty high. I did see the logs, and they were about 105-110 degrees on a 85 day. We pulled the headlight out and put a blower pointed at the airbox and were able to get some better numbers. So my next project will be ducting to that airbox.

He also suspects my exhaust is another restriction right now specifically the headers, but it's making enough power for me as of now.

Its the stock section 1. I'm at 338whp with the full BW race, megan headers and OE intake mani. MSR Houston dyno on a cooler day. 70s?

Really strong number for OEM software. Reach out to HTE and probably EAS as they are LA based i think, or california. I think you might get close to 340-350whp. There's a lot left.

glad to hear it’s strong numbers I wasn’t sure with other dyno numbers with similar mods reaching 350+
The car dyno’d at EAS, I’ve heard good things from hte would like to get close to 340’s.

Dyno’d my E46 M3 car has sub 50k miles
mod list:
OEM CSL AIRBOX
OEM CSL CAMS
OEM CSL EXHUAST VALVES
OEM CSL HEADERS
SUNBEAM 100 CELL
OEM CSL SECTION 2
DIXIS BACKBOX
OEM CSL SOFTWARE

car made 326whp and 242 torque. Contemplating getting a tune done to sneak in some more power if anyone has any suggestions on who to go with would be appreciated. I thought the numbers were pretty close based off me going after the oem CSL ratings.

My Z4 M coupe has been running Epic software from day 1 but I only recently managed to find time for a custom tune. I never did a stock baseline but I know a healthy Z4 M generally dynos around ~275whp (SAE) on a Dynojet. But for purposes of this exercise, I’ll use my header tune as my baseline, which means total pickup of +40whp from airbox, x-pipe, pulleys, and flywheel. Note dyno runs were performed at same facility with ambient temps being quite similar (spring 2024 vs fall 2025).

Lastly, I recognize a more controlled framework would've entailed starting with a baseline header + custom tune but frankly, I wasn't going to pay up for an academic exercise. Ultimately, this answered the most burning questions for me while still having good relative comparison points.


Header Tune (OTS)

• Euro headers
• 100 cell hfc
• Peak 298whp / 237lb-ft

Alpha N (OTS)

Same as above plus following additions:

• TMS CSL v2
• TMS pulley
• Supersprint X-pipe
• TTV Racing flywheel
• Peak 318whp / 241lb-ft

Alpha N (Custom)

• No change to above other than tuning
• Note there were quite few runs and iterations of the tune but this was the "final" version
• Peak 337whp / 256lb-ft

Did you lift at 6500?

[x Spades x]

2006 M3 ZCP
Manual
95,800
Bone stock (for baseline pulls)
Dynapack (Hub dyno)
279HP
272TQ
(we took the 2nd highest as the highest looked wonky/glitchy)

[3staxontheradio]

EPIC Alpha N tune
SuperSprint Stepped headers
3.5" custom exhaust
4" custom intake with ITG filter
Tilton clutch/flywheel
Underdrive pullies


327WHP, 260WTRQ(#'s are SAE corrected), however this motor will end up detuned for classing purposes.

Whats the muffler setup and what diameter choke did you go with on the merge to 3.5"?

[GregS86]

NIce! Swaintech coated headers?

Yup.

[fourmula1]

Impressive power - are those stock camshafts?

Yes, stock, nearly 100k miles on engine and only been open for rod bearings, vanos, and valve adjustments.

[paulclaude]

I run detuned to 295HP for GTS3 but this is my max power tune.
2003, 97k miles, A LOT of track hours/miles.
Karbonius Race CSL Intake
Status gruppe headers cut band clamped to BW race section 1
BW race section 2 and 3
Tilton clutch
Underdrive pullies

Suggested he cant get enough fuel to it to push further....at this point it is lines or fuel pump I assume, everything else has been changed or cleaned. Not that I need more for my class.
