W211 Upgrade Dyno Results
Guys
Just got the car back from a day with Powerchip. There are still some little bugs to work out in part throttle mapping, but the results have been spectacular to say the least.
I will avoid talking peak figures, only because of the differences in different dyno, operators etc. I have sufficient experience to convert the numbers for between the different dyno's but it is probably more complicated than in needs to be.
The results are a comparison on the same Dyno with th same operator. As a final note, the final results were made at an ambient temperature 10 degrees higher than the baseline. Those of you who understand superchargers will note that the relative correction applied by a dyno for temperature change does not sufficiently account for the difference in real power seen, so it is safe to say that the real power increase is infact larger than that shown.
The car has a 50kw (70hp) increase in peak power at the rear wheel starting with a 30kw increase from 2500rpm, moving to a 50kw improvement from 3000rpm which is basically held until the power peak.
Peak torque is made at 3100rpm resulting in a 30% increase over stock through the entire range.
These numbers have been done on a Dyno Dynamics, not a Dynojet. There are no real fans, either for effective cooling or to recreate a ram air effect. Additionally the designers of the Dyno Dynamics write their software to work on an estimated 30% drive train power loss. if you add around 10% to these figures you will get equivalent Dynojet numbers.
On my G-tech Comp I am seeing sub 13sec 0-200kmh (125mph) times and sub 12sec standing 1/4's. The car is faster than a CL65.........
What has been done to achieve these gains?
Heatshielding for intake system.
S500 airtube and modified inlet entries.
BMC filters.
ASP pulley kit (well actually we have remanufactered the pulley in Australia after using the ASP as a pattern)
Longer supercharger belt and smaller water pulley pump to suit.
Powerchip ECU upgrade. - as mentioned there is still some partial throttle mapping to be sorted, which will be done over the next couple of weeks.
Results: AWESOME!!!!
These results are 50% better at the rear wheel than the equivalent Renntech kits flywheel claim.
Bottom line a very economical proven 100hp power upgrade!

If I'm not too lazy i'll scan and post all these results tonight.

HOLY COW!!! Awesome results! What are you doing about traction?
BTW, I have the PowerChip ECU in my W210 E55 and love the jump in the low and midrange. They claim only 17-22HP peak but it feels bigger.

Do they have a website and a pricing sheet?
Thanks for the info.

Maybe I'm reading this wrong? The standard loss for a Dynojet is around 12-15% for a manual and 18-20% for an automatic. If the Dyno Dynamics figure 30% drive train power loss than are you saying the DynoJet is actually 40% drive train loss? Maybe you meant to subract 10% from your figures?

i think you are reading them wrong. The Dyno Dynamics reads lower power numbers than the Dynojet, similar infact to the Mustang dyno used in the US.
I thought Dynojet used 21% for modern autos and 18% for manual? Real losses are somehwere around 12-15%, but that is irrelevent, it is the no the software programmer used when he wrote the code for the dyno.

OK, I did a little research and I see what you were saying. A Dynojet usually will read the cars RWHP 10% higher than what a Dyno Dynamics dyno will give for RWHP on the same car and the same conditions. The general concensus seems to support this information.
"Additionally the designers of the Dyno Dynamics write their software to work on an estimated 30% drive train power loss. if you add around 10% to these figures you will get equivalent Dynojet numbers."
The designers of the dynos were not trying to predict drive train losses; rather, the programming for determining RWHP on the Dyno Dynamics will just report lower hp on the same car than a Dynojet. So, you will have to subtract 10% of the power from the DynoJet's RWHP to equal what it would read on a Dyno Dynamics. If the DynoJet reports 100 RWHP, your would take the 100 RWHP and subtract 10% or 10 RWHP to get what a Dyno Dynamics would report or 90 RWHP. That's a pretty huge gain in hp you are reporting on the 211 E55!
"The car has a 50kw (70hp)"
1 KW = 1.34 hp. A 50 KW increase is actually 67 hp but that is still a pretty large gain. I'm sure you were rounding for ease of comprehension though.

W210 E55 Dyno
This is what you can expect from a chip job on a NA car.
W211 E55 Base, Powerchip and inlet mods.
Last time I achieved a further 10kw gain with fine tuning over the original results from Powerchip playing with the factory fuel enrichement and timing settings.
Almost Finished.
I'll post the final results in a week or so after fine tuning is completed.
As you can see I saw a 30kw power gain at the rear wheels through inlet and chip tuning and 50kw so far, with the addition of the pulley, with an expectation of 60kw. This is a 20% increase in rear wheel power. Note the torque increase 30% across the range!
If you have a W211 this measured power increase is almost twice that provided by the Renntech kit at almost half the price.
You may notice that I use two dynos, the B&M one used by Powerchip to do the original tuning work and the second, JPC to check the integrity of the numbers and fine tune the car.

Very nice. I think what impresses me the most is the huge gain at low RPM. That torque curve is FAT at the bottom!
Tell me you've found a way to sqeeze some 305mm tires out back and I ready to buy!

Impressive results stephens!! Are you going to set up shop in Melbourne and become the premiere Aussie MB tuner? Might be lucrative?

I'm confused...this whole topic is about how much power increase from what...just the powerchip itself? What else was added if anything? Sorry jus a lil confused. If I'm correct the chip gives you that much hw increase? Is this the 91 octance program or the 93???? TIA

The first graph is of my old W210 E55, showing the improvement from chipping the car.
The second graph shows the improvement over stock with firstly Powerchip, BMC filters and inlet modifcations. The third graph is fine tuning of this setup and the final graph is the addition of a pulley kit and ECU retuned for the higher boost.

BenzoBoi,
Read stephens first post and look at the mods. It appears to me that he is developing a tuning package for W211 E55 that will produce superior HP gains for less money than other tuners are charging. Someone asked him about the ECU upgrade for W210 E55 from Powerchip, which is available but doesn't produce nearly the gains he achieved on the W211 E55 in conjunction with the supercharger pulley upgrade. Hope this helps!

AHHHH thank you good friends. Hmmmm sounds interesting...I will keep my eye out on this topic. Thank you...and of course if anyone hears anything further bout any performance products such as ecu's or pulley's for the W211 E55 please keep me updated also. I am really looking into upgrading the performance but don't want to give renntech or kleemann an arm and a leg...thanks again Stephens and James F. Cannon for the info...

Marcus Frost,
Sounds like what might not work in Australia may be right for the windy city! By the way, checked out your club website and saw some very nice rides. How does one qualify to join the club?

That is a good question.
I have known Wayne Besanko from Powerchip for close to 10 years now as a customer, nothing more.
My car has been used as the development "mule" for the supercharged AMG motors by Powerchip since they all use identical ECU code. In exchange for this I have received discounted pricing.
I don't have any info on the W210 chip, I only know about the W211. I suggest you speak to Powerchip or Evosport about this.
