BIG LUV

Dynoed my 55 today and made 402 whp and 465 wtq on a notoriously conservative/low dyno. Did 2 runs completely stock, and 2 runs with the green filters in. Green filters only added 1whp. Relatively cheap hp/per dollar ratio.


Here is the link to my dyno sheet and video's on the dyno. I am not e-literate so my buddy Jared hosted them for me.

looks good.... thanks for posting the results....

Can't see the video and dyno sheet . It says that you must register first on that site in order to view?

Healthy Beast. What year is it? You are running a bit rich up top but to be expected. The car has great tork! MOD IT.

BIG LUV

The guy that runs the Dyno builds 6 sec. Mustangs and Chevy's, he was quite impressed and thinks it has at least 20 more whp if he could lean it out. I am still debating what tuning company to go with and to be honest Activie Autowerke's is starting to look good, but I will probably go Kleeman or Evosport. I can get a great deal on Renntech through a friend, but they seem too conservative. I have some time to figure it out. I don't want to mod it until I hit 4k on the odo. cause I want the piston rings to seat properly.

NICE........ i got a 04 E55 stage 3 kleemann i just dynoed it i got 470whp...... but i got the same problem like yours which is the mixture... i spoke to someone from kleemann they said they cant do anything for that, it goes rich cause of the heat, it protects the engine.... please tell me if there is a way to make it leaner..

enzom

Your A/F is off the chart. Literally.

BIG LUV

Can they lean the mixture using the MB Star diagnostic machine?

bsimonson

nice numbers.

E55 RUSS

What do those number adds up to at the CRANK ???

BIG LUV

Is it 25% or 15% drive train loss?

bsimonson

IIRC manual trans is about 15%; AT is more.

BIG LUV

45acp

I thought Active Autowerkes only dealt with BMW's. I guess they're dipping into MB's now?

E55 KEV

With that in mind - what are the estimated Flywheel HP for the sheets above?

Fikse

depends on the % used.... 16% would be 466/539...

catalystkid

Actually using a 16% drivetrain loss would put it at 479/553. Very impressive torque for a stock car.

korveine

just wondering, what if ones does the ECU reset trick and then run on the dyno again... would that increase the numbers any?

2MANYCARS

It might during the first run, but after the ECU completes the readiness checks, the car would produce similar numbers prior to the reset given the conditions of the dyno runs aren't different from each other.

E55 PWR

The absolute best automatics will not be better than 19-20% (typically autos are 20-21%. The best front engine rear drive manual transmission cars wont be better than 17%. And the best rear transaxle cars have 15% drivetrain loss. 19-20% are the numbers you should be using.

m52e55

any reason that RENNtech on website for dynosheets recommends 1.23 (assume 23% drive-train loss?) multipiler for rear wheel conversion to crank. can see if independent dealer selling the mods would maybe market this way to entice buyer , but for RENN to post on site seems interesting. any idea why that conversion factor? thanks.

ChicagoX

Actually, that works out to about 18.5%.

400 rwhp TIMES 1.23 equals 492 crank hp.

400 rwhp DIVIDED by .815 equals ~491 crank hp

I hope this helps.

E55 PWR

23% is too generous, tahts just boosting their numbers to make them look better. AMG autos are the best out there so they are probably right around 20%. sport autos are around 21%, the absolute worst autos are 23-25%. if you use 20% it will be closest estimate to your real cran k numbers. 1.23 is too high though thats for sure. Its DEFINITELY not the 15% that alot of these guys on the E55 forum have been claiming, those numbers are WAAAY off. hope that helps.

ChicagoX

1.23 is 18.5% loss.




1.23 is 18.5% loss.


I hope that helps. If not, get a calculator.
