Cool VT625 Dynapack Results, Over 650whp...

Special thank you to Robert (PG) for doing all of the documentation, logs, charts, vid, etc. and Shawn at Church Automotive, for use of his Dynapack, it is very much appreciated guys.

*****Here is the updated info now that we received the boost logs from Church. THANK YOU Robert for your hard extensive work here and posting all the Empirical Data for the rest of us to learn from.


Car and Modifications:
  • 2008 BMW M3
  • ESS VT2-625 Supercharger
  • +Water-Meth injection
  • DCT
  • Catless STOCK exhaust
  • 94 Octane
Conditions:
  • Temparature:: 77.22 degrees F
  • Atmospheric pressure: 29.95 inHg
  • Humidity: 57%
  • SAE Correction: 0.99
  • SAE-Adapated (Dynapack): 1.03
  • Uncorrected: 1.00
Results:
  • SAE Adapted: 657whp @ 8400 RPM, 425wtq @ 7700 RPM. 8.05 PSI
  • SAE-Corrected: 631whp, 408wtq
  • Uncorrected: 636whp, 411wtq
Dyno Database:Dyno Results -- SAE-Adapted:








All Dyno Runs -- SAE Adapted:




Air Fuel Ratio:







Comparing Dyno ECU AFR's to Dyno
AFR's:




This graph shows the difference between the AFR's read via OBD port, and
those seen by the AFR sniffer on the dyno. The AFR's on the OBD port
are exactly what the ECU sees, and the AFR's fromt he dyno come at the
tail end, after the mufflers, etc. Since the ECU reads Bank-1 and
Bank-2 AFR's, both are included in this comparison. It appears from
this graph, that the dyno sees the AFR's a little leaner than the ECU.

Boost Log Analysis: 8.05 PSI

Video:


Dyno Testing Procedures:
All of the dyno runs are filmed in HiDef video to document the
authenticity and independence of the tests. A Kestral 4500 portable
weather station is brought to take independent weather measurements.
This provides a cross-check for the dyno weather station to ensure that
the dyno weather station is reading accurately and has not been tampered
or altered in any way.

Dynapack settings:
  • Range: 2000-8600 RPMs
  • Gear: 4th Gear DCT
  • Dynapack gear ratio: 5.29 = 1.68 * 3.15
  • Ramp Rate: 1 Sec = 400 RPMs
  • Ramp Time: 16.5 seconds = ((8600-2000) / 400)
  • Settling time: 2-seconds
  • Lead-in: 20 RPMs
Additional Information:
  • There is no ice packed on the manifold.
  • No water sprayed on the intercooler.
  • No extended cool downs.
  • No 10-minute breaks between runs.
Just:
  • ESS VT2-625 running production software
  • 94 Octane +Water-Meth
  • And a catless STOCK exhaust

Individual Dyno Results:
Individual dyno results are shown below. SAE corrected results are shown
twice, using two different sources. The first source (dpc) are the SAE
corrected results straight from the Dynapack. The second source (sae) of
SAE corrected results are obtained by using the Kestral 4500 weather
station data for each individual dyno run and running it through an
independent SAE correction formula. This ensures that the dyno results
are accurate and can be independently audited and verified for
authenticity and accuracy.

The legend below has the following meaning:
  • Dyno Run: Dyno run file
  • Boost Avg: Boost calculated using trend line. This is the "official"
    boost for this dyno run.
  • Boost Peak: Peak boost observed on this dyno run.
  • Temp(F) = Temperature (Farenheit)
  • RelH = Relative Humidity
  • Pressure(Hg) = Barometric Pressure
  • DA(ft) = Density Altitude
  • WHP(unc) = Uncorrected wheel horsepower
  • WTQ(unc) = Uncorrected wheel torque
  • WHP(dpc) = Dynapack SAE corrected wheel horsepower (SAE-J1349)
  • WTQ(dpc) = Dynapack corrected wheel torque (SAE-J1349)
  • WHP(sae) = SAE-Adapted wheel horsepower (SAE-J1349)
  • WTQ(sae) = SAE-Adapted wheel torque (SAE-J1349)

* Entry used for the Dyno Database

Boost Log:
Dynapack changed their file format and we can no longer read the files.
We had to rely on the dyno operator to export the dyno data as Excel
spreadsheets. According to the dyno operator (Shawn Church) the boost
gauge had a static pressure of 0.13 PSI. Shawn explained via text
message that 0.13 PSI needs to be subtracted from all boost gauge results.

i have no doubt in my mind...... the ESS 625 system for the m3 platform is imo, simply the best option for the s65........ absolutly insane power and seemingly, reliable also!!
well done Ess...... wish my Vt2-500 z4 could get 500rwhp....

That is serious power Drew!!! Congrats brotha, as always your car never seems to disappoint. Dumb question though, what does SAE Adapted mean?

Well, better to be conservative with the ratings and overdeliver, than overrate and underdeliver, no? .

EDIT: (found it)
There are two SAE horsepower correction standards. Dynojet uses the earlier (pre-2004) standard. "SAE-Adapted" is the newer (updated) standard.

WHP(unc) = Uncorrected wheel horsepower
WTQ(unc) = Uncorrected wheel torque
WHP(djc) = Dynojet SAE corrected wheel horsepower (SAE-1340 PRE-2004)
WTQ(djc) = Dynojet corrected wheel torque (SAE-1349 PRE-2004)
WHP(sae) = SAE-Adapted wheel horsepower (SAE-1349 2004+)
WTQ(sae) = SAE-Adapted wheel torque (SAE-1349 2004+)

Got the info from PencilGeeks thread.

How do you explain the 90 rwhp and 50 lb rwtq gain over your recent dynojet at the same boost level other than "different dyno"?

It's actually a 45whp and 29wtq difference, when comparing both SAE CF #'s. IMHO, the different type of dyno is the main reason.

Excuse my ignorance, but what's the point?

I'm sure I can get a blower to put out 1000whp but the car will blow up in a few days. The more power the higher the chance the car will blow. You've already blown up one motor, why not just limit the power to a safe and reliable level? If whp is the goal, why even drive a M3 in the first place? Just get some Mustang or Corvette or whatever else puts out monster numbers. This whole whp race seems utterly retarded...

It's not your thing, nothing wrong with that and you are entitled to feel the way you do. However you are reading more into it, it's simply a thread reporting dyno #'s that were put down on a Dynapak at 7.2psi. It's far from 1000whp, and that is not my goal, but like MANY others on this board, I wanted more power and wanted to go faster, hardly an odd thing to report on a sports car forum.

I understand your points on the motor, true for the most part the more power you make the higher the chance you can break things, but other factors play a big role as well. My first motor blew probably because of a meth failure while running 9.3psi and 91 octane. I don't run that much boost anymore and I only run at minimum 93 octane, and have proper hardware installed this time around with the WM system, and it's not dependent on the Meth to keep the motor safe as it was before, but again I do understand your concerns. FWIW I have modded just about every car I've ever owned and never had an engine failure, it's not fun, but I would not have done this again if I did not feel confident with the kit and the people involved.

lol, because I didn't want a Mustang or a Corvette I wanted an M3 and wanted to go faster, it has nothing to do with a whp race, it has to do with enjoying my car the way I want too, just as the vast majority of the other forum members are doing on this forum who mod their cars. Certainly you can't argue with the amazing results, unless you're not into that sort of thing, cleary you're not.

the guy is reporting his dyno numbers to the forums... seriously dude what was the point of your post?? better yet whats up your ass??

great numbers DLS. ESS FTW, hands down. 657rwhp is more than 710 at the crank thats about 750-760 hp at the crank if you calc. a 15% loss roughly.
