S54 Dyno Database

[digger]

Tested today my streettune on a Maha dyno to check the work, sadly don‘t had the time to make a baseline run with stock software. Maha Dynos have here in Germany a very high reputation, even manufacturers (including BMW) use them. Only downside is, that they don‘t output „correctly“ WHP figures, only Crank Hp (corrected Crank HP with EWG like factory HP figures and not corrected Crank HP).
This was discussed previous with Martin on Page 2 or 3.

its says 244whp uncorrected which corrects to 252whp

^^^ Congrats, not super familiar w/the Maha dynos, but looks like a good running car regardless!

Dyno Operator showed me a couple of other E46 m3 runs from his database, they were around 310-342 Crank HP corrected. And one dyno plot with a airbox, tune and not known other mods at around 360 Crank Hp corrected.
I think operator made a small mistake while synch rpm, because I set limiter at 8200 and dyno result‘s go a bit further. But estimated HP should be same.

my setup:
- complete Euro car
-freshly done Vanos and valveclearance
-CSL Software with MAP
-Karbonius with CSL Flap
-Viscofan delete (Spal)
-Muffler mod
-modded midpipe
-8200 limiter
-street tuned

Temp: 22-23°C ambient temp in Dynoroom and ECU measured 50°C intake Temp due heatsoak. After 3500rpm IAT normalized itself due airflow to 30°C.

Fuel: premium pump gas (Aral Ultimate 102 octane)

in the logs I see definitely more ignition retards in high rpm‘s (cylinder individual) compared to my street pulls. And I have to rework the area around 2000-2500rpm where I didn‘t spend time while street tune.

Recently got my street build on the RK-Tunes dyno for a custom Alpha-N tune. Mods:
- Karbonious CSL airbox
- 280 272 Cat cams
- SuperSprint V1 Header, SS Catted section 1, SS oversized resonated section 2, SCZA muffler
- TMS pulleys

After Jordan doing his thing we ended up with 350 WHP & 261 Torque. Pretty happy with that.

Nice build and results Rob! Thanx for posting man!

plugs had maybe 10k to 15K miles. Is there a guide to perform a VANOS test? can it be performed with the schawben scan tool? Thanks!!

Plugs should be fine w/those low miles. I believe that a Schwaben will perform at least some of the tests, but not all? I've always used a GT1 type tool, but there are other means of running a VANOS test. Maybe search in the Coding/Tuning section for other recommendations.

How many miles on your plugs? Might want to perform a VANOS test as well.

Kassel thought it was plugs being a bit old. I replaced them but will not be able to get back to them for another run.

Why is it nosing over at 7,000rpms? Have you performed a VANOS test recently?

So what should I do next for more NA HP? Is the next step cams?

Yep. Though, I think that the current setup is solid as is. The funds might be better spent on a few DEs or track days.

Full Supersprint (Stepped headers, race cats, sport Muffler)
Kassel MAP conversion, CSL Conversion
Turner CSL air box
Kassel dyno tune (mustang dyno)

Nice numbers man!! What BW turbo are you running? Turbo manifold?

Thanks! It is a maxpsi e85 kit with Spa manifold and the BW 364.5 sx-e

[SliM3]

I’ll update mine, ~770 whp and 700 ft lbs. The BW maxed at 25psi, I’m planning on ordering a xona rotor hopefully. The afr was lower by .5 or so on the wideband in the car but still looking a little lean.
