S54 Dyno Database

[George Hill]

When you say stock you should be more specific.

...

I am afraid to mentioned that for a stock engine with the mods you
have you are actually down on power..

Hi Anri,
I think you misread my post.

The blue M3 is stock, it has 0 modifications, not even an air filter. We put it on the dyno to see what it makes in this configuration and now that we have a baseline number we will swap on the SS V1 headers/cats and down the road it will get a Dinan CAI and Muffler. So considering this car makes 294 avg and compared to your numbers of 275-285 that is why I think this dyno is optimistic.

My wagon, Eileen, has made previously 307whp when it had the 6MT and KK headers on a stock Euro M3 tune on a different dynojet. That facility no longer rents their dyno to the public which is why I have her on this one. I've had my hands on a few ZF 8HP45 swaps now and every one seems to be down on power with the auto compared to the manual transmission, we were curious if Eileen is as well and I think this confirms that she follows that same pattern as the other cars. Its not an apples to apples comparison but it certainly trends that way.

I don't think that a stock S54 makes 294whp on the average dynojet dyno.

We've also had a car on their dyno (at the old location, but same machine) that then went on a couple other dynojet's and made significantly less on those. Either way though, in this situation the number doesn't matter, it's the delta we are interested in.

Hi,

When you say stock you should be more specific.

The cars above you have dynoed are not stock. Even if you
change the intake/filter system is not considered stock any more.

In your case above you have full exhaust system and a tune,

If we bring a bone stock M3 from EU market and put it on the dyno
it will show more power than US M3 same engine.

If you take un-touched US M3 and put it on the Dyno-Jet assuming
cranking compression is min 185psi on all cyl and vanos timing is
perfect they make all day 275-285rwhp SAE Dyno-Jet. I have access to
around 20+ S54s with various stages and performance parts. You
should not example one s54 did not make power on the same dyno
if you tell me 20 cars sure, but 1..

Removing the exhaust restrictions and tweaking the ignition timing
map and Vanos map it will add power.

I am afraid to mentioned that for a stock engine with the mods you
have you are actually down on power..

George,

Could you explain yourself why do you think
the numbers are optimistic ?

Those are srsly healthy numbers for a 'stock' M3!

^^^Thanx for posting/contributing to the dyno base, and look forward to the results after the exhaust upgrades! Those are srsly healthy numbers for a 'stock' M3!

Baselined a stock 6MT car the other day and put my wagon on to see where she's at.

Eileen, average of 297hp and 245lb-ft of torque. Sporting a "stock" S54 long block, euro headers and singe exhaust out the side, along with a Dinan CAI and a Mark D'Sylva tune, drivetrain is 8HP45 transmission with 4.44 gears in a non-m rear diff.

Scott, average of 294hp and 243lb-ft of torque. Stock, getting SS V1 headers, cats and Dinan muffler next, this is our baseline pull to see the delta in change.

Just ordered cams, followers and maybe an airbox so all of that will be going on with the SS V1's and full SS 63.5mm dual exhaust in the next month or so hopefully. Will be retuning and dynoing at the same dyno. Stay tuned 😈

Thanx for posting up, and contributing to the dyno database! On a side note, graph looks great up to around 7K, then appears to flatten a bit? Have you checked your VANOS and/or cam timing lately?

Vanos rebuild along with rod bearings is planned for this winter.

did he try to fix the issues at 2000-3400? that's not right and torque dip reflects that

Car was running pretty lean. Hassan added a little fuel there to be safe. There’s about a millisecond of a hesitation if burying the throttle 2-3k, otherwise buttery smooth.
