Dyno...SL55-Ypipe+Thermo_isoation with my set-up
Well, I am here again with another Dyno.
This just has the SL55-Ypipe and the Thermo_isoation.
Conditions, very bad, 97 degrees Dynorun.015 vs. baseline Dynorun.009 74 degrees.
http://groups.msn.com/Mercedes2003C3...oto&PhotoID=42
Outcome, same hp but again, big improvement in TQ (7.8 rwtq peak), specially low RPMs that makes my car have a better off the line, as well as I mentioned after the installation of the SL55 Y-pipe, based in my set-up, huge improvement in acceleration response.
Also, there is increase in the power band at low RPM’s as well.
Well now is my big dilemma,
Why….I can not improve more in peak HP…?
What do you think guys?
My AIR/flue ratio:
http://groups.msn.com/Mercedes2003C3...oto&PhotoID=43
At this point, I am really lost, I do not know weather or not is my ECU tinning or I have to up-grade the exhaust (headers, resonator, etc)???????
Originally, my next step was the EVOsport’s headers, but based to the fact the I am here at 5,450 fts using no correction values my rwhp is 264 and rwtq 274, thus I believe that the stock exhaust works just fine, doesn’t it????
Thanks!

Pierre: Couple of thoughts. My understanding of is that SAE correction factor works very well in correcting for temperature and humidity. However, once you exceed certain alttitude the correction factor is off.
Secondly, try running with stock air filters. I think you might be surprised.

Thanks Vadim!
Shine, I chaged for the RENNtech ones (ITG)..... and I am thinking seriously to retun with them...or follow Vadim suggestion to go with the OEM ones.
either way guys...
I believe that the best test is going to the track, probably next Wednesday. I have some times for Cory (CLK43K) and Bradom's car (E50K) as base line.
Thanks again!

What do you think a 192mm crank pulley for C32AMG ?
(ODPS is around 180mm)
One aggressive ODPS guy is doing this and smoked a 996 Turbo
that makes our C32AMG team very very proud of it.
W211/E55 team is now worry about this.....![tyson](https://mbworld.org/forums/images/smilies/boxing.gif)
![Big Grin](https://mbworld.org/forums/images/smilies/biggrin.gif)
Do you know the TQ limit of C32AMG ?
One Kleemann C32K here hitted, 520 NM, cut the power.
We're expecting Evosport headers & s/w as well.

Here are the latest times (Bandimere Raceway 5,280+ ft above sealevel):
E50K: 13.499 @ 105.7 with ESP and A/C ON
CLK43K: 14.220 @101.64 with ESP and A/C ON
We will be going to Bandimere on the 23rd as well (mile high nationals are there this week and the test and tune night is cancelled). Ive done some ECU tweaking as well as better tires so I hope to improve my times a few 10nths. Cory has done some work with the CLK as well, should be interesting.
See you there! Lets try and line up together eh?

Thanks Brandom (Kleemann USA)!
I will call you for arrange, I will do everything possible to be there, although it will be my fist time in my entire life at the track, I hope I can do decently
I will do my best![thumbs](https://mbworld.org/forums/images/smilies/thumbsup.gif)
Awesome Shine,
well my car is doing 550 Nm peak, and at really low rpm I am over 500, I would say 2,200 rpms until 5,500![thumbs](https://mbworld.org/forums/images/smilies/thumbsup.gif)
Vadim's car is doing much more like 580 Nm
and I believe is the highest reported
with no 3.8L
Finally, yesterday night I made another video from 0-120 test, video that I have done before SL55-Y and Thermo, and although the Dyno is not showing differences, my car is going a 1.5 second quicker 60-100, now in just 6.5 second here at 5,450 ft
Shine, I believe that I will clean the BMC and installed.

SteveL you are absolutely right, sorry guys!
May be other factors, and the track may answer it, if I can put the car of the line well.
Thus, I just rechecked the videos, a few times (6) more and I did not take the times accurately
, starting from 0, 60-100 I am doing 7 sg. definitely at 5,280+ ft above sealevel, which is ½ second quicker than not including the SL55-Y and Thermo with my mods.
Thanks!

Shine: 192 mm crank pulley will require very small water pump pulleys to clear. Reliability will become a concern.
Do you know how much boost he is making with this setup?

No boost gauge in his car, guess 1.4 bar by linear regression.

Finally got my C32 SL55 Y splitter hook up.
I notice the low rpm TQ improved, though it helps less on peak TQ
(HP ..... the same word)
The residue air increase by larger hoses, so is the TQ in lower
rpm.

Shine....
you need now ECU work (Kleemann, EVOsport, RennTech, H&S), becasue the stock program is not able to feed more gas to the system at high RPMs....remember that you have pulleys+Y-SL55+BMC is much more air.
I went to the track las 23th and I run 2 times, Brandom could not make it. I did not good, due to my really bad 60" 2.3 sg I did 14.2 sg, almost identical number than Cory's CLK43K. This time here at 5,250 ft is really good, coparing that a M3 SMG is doing 14.7, Viper 14, and EVO VIII with boost controler 14.5 s.
Now, today I am going again, but with more tips how to start the car properly, and I should be 13.7 sg.."my goal", although it is a really sunny hot day 85-90 degrees.
Finally, I had had a long conversation with people from H&S and .... I discover why my car is increasing at low hp & tq and not that much at high......my car has a MULTI-OCTANE program
.... my ECU has a program that has different rutines for different enviroment and gas conditions.....believe it or not I have a extremately similar program and standars that the 500 hp C32 twing turbo http://www.autospeed.com/A_1447/page1.html , where Mohammed Ben Sulayem has chipper almost all their cars with H&S......the reason is because at those countries there is a really high temperature of engine working and based in the octane that you use the ECU adapt....
so, :
- my car with 91 octane will never run more hp and tq at high rpms than a RennTech, Kleemann software.
- a stock C32 runs a max of 95 (US) octane with no ECU tunning, but although you may use 100 or 105, there is NO gains.
- when the wheater is over 75-76 F or 22-23 C degree the C32 stock or tunned ECU start pulling back slowly, slowly, and so on with high temperatures.....for that Shine you have to increse the Octane quality.
- My car based in Thomas statiment can run a max of 105 octane when is really warm day, where the ECU is simulating at 5,250 ft (less oxigen) and 85-90 degrees, the middle east wheather paramenters....... NOW when the temperature drops...NO gain with 100 or 105, just with 93-95 the car runs just awesome (I have not dyno) at 76-86 degrees...more degrees I need more octane......thus for that at the dyno with 91 octane and 86-95 F, I just got improvement in low and not high rpms.
Ciao

Thanks for your advice.
We(ODPS users here)are all running stage-2 10% richer feul mode.
The most aggressive guy put 192 mm crank pulley(ODPS 180mm)
can pull ~6 CL ahead of us,62 to 125 mph
a 996 Turboish C32
Looking for remote ecu tunning solution
we did that for Vmax delimit, 40 minutes.............UK/Superchips

What do you mean by remote ECU tuning? Local adjustments without pulling the chip? I'd love to delimt that way...

Shine,
How much richer? I mean which is the octane that you guys are mixing..... I have here at Denver, 93, 93.5, 100, 105....the cheapest one is 93.5 at Petro Stop $1.65 a galon. :p
I have not dynoed my car with more that 91 octanes, but I will.
192 mm crank pulley!!!...WOW
Thanks!

so who makes this 192mm crank pulley and what other pulleys need to be modded in order to fit? I thought the 180mm pulley already barely fit?

We've 98 octane here.but I rate it as 95+
Since no Powerchips...dealer here, it's hard to let them guess
what we are in octane precisely.
I don't trust UK/Superchips doing the MB s/w tunning here.
Blando
Find the coorelation of boost & crank pulley diameter.
Sorry, I mean the database link, the local dealer can do the
s/w rewrite & delimit on the ecu chip quickly.(~ 40 min)
Sure,same stock ecu chip but delimited.
Kenny
I don't remember the detail, a few more pulleys need to be shrink for clearance.
We're probating the 192mm & really appreciate that aggressive volunteer
