I'm just getting back from a late dinner with Rich from Dyno-Comp. He tells me the C55 is running great. Power is low (but very respectable) only because the boost is low at this point. He explained it to me as a "one step at a time" job. with a major task of diagnosing and installing a new wiring harness. It seems a major hurdle has been cleared and they are on to the next step.

Mike, what was the hurdle? The MAF??

As far as I know, and its not much... The MAF issues were only the start of diagnosing the whole issue. It was more or less a symptom of the underlying problem.
One thing is for sure Dyno-Comp is going to give Robert back his car much better then when it was dropped off.

Looking back. Maybe I should have left the compression ratio at 11:1 stock instead of lowering it to 9:1. I lost some power at low boost compared to stock but am unsure DynoComp can get it back and more once the boost is raised. If they cannot tune it at high boost then the Mahle pistons and rods were just a big waste of money as was the $5K+ transmission.
It's been incredibly difficult to modify a C55 for max power compared to a CTS-V with some simple mods that will get me past 600rwhp and run reliably like a daily driver. Lesson learned over and over again.

Better as what..............???? For $12K already spent on.......in my eyes and his, it a total failure if he does not get at least 500 rwhp. He were already making 440 rwhp when he drop the car. I'm really worry about the MAF limitation just because you guys were not able to tuned around it on your old C55 kompressor.

Dyno-Comp is working with what they are given. They did not build this engine, they did not port the heads nor do the trans. Dyno-Comp is doing what it takes to repair damage caused by other places. Along with things that where not working properly. DC basically has to go over everything others did. Then to basically use some of the things others did, like the pistons and what not. That can be a bit of an unknown.

+1, I guess with you I am preaching to the choir. The C55 is eminently difficult to mod compared to the C32. Ask anyone who owns BOTH and they will agree with me. Barring an SC and some internal engine rebuild like you've done(pistons/rods etc) there's not a whole lot, other than exhaust and tune (and the tune is dubious) that brings more powaa to the C55. Its just the way it is. AMG/MB did a lot of factory tuning to bring the C55 to where it is. For some reason tunes seem to work better on the C63 than the 55??
This is why so many in the past skipped over the 32/55 and went to the E55 (04-06) to get max mods out of the platform. Just ask Jake at EC, he'll confirm exactly what I am saying. He's worked on all my cars...........I wish you the best and hope to see a very strong running 55 soon!!

Mike, Actually the re-built engine and new tranny produced 440+rwhp on Evosport's Dyno before I brought it in. Richard even dyno'd it and I have the dyno sheet with a reading of 415rwhp on his Dyno-Dynamics during last summer. The AFR was perfect and the car was running smooth. The car was running beautifully when I brought it in to Richard on Feb 11th...My friend drove my car numerous times and can attest to this. I'm still optimistic Richard can get it to 500rwhp this Friday.
Ahmad's Car (BlkBnzz) is very strong and he's got similar mods to you..............

Your were right Brad. I have to admit. I should have done it sooner and saved alot of diagnostic time and headaches for everyone.

Almost done. Car runs "Perfect" according the Ricard@DynoComp but the power is still low at 445rwhp/480rwtq on the Dyno Dynamics in triple digit weather conditions. Car is running on 7psi but on Monday they will raise the boost to 10psi and apply the 100 octane map to finish up the car.
He told me that we could see 500rwhp on a DynoJet but probably a little less on his DD Dyno in that AZ heat and no engine adaptation time.
Car is ready for pick-up by Friday. I'm just glad this saga is over. I may or may not have the world's fastest C55 but who cares anymore. I just want to enjoy it and get ready for my next super-sedan project (800rwhp CTS-V) early next year (post bonus and tax refund).

Can't wait to hear your hi octane numbers! Sounds like a beast.
I too would have gone the domestic route if I did this again... but my build ended up with something not seen on every street corner..... so I'm happy.
Do you plan to get some 1/4 miles or just enjoy it on the streets?

Right now, I guess I could go with even a little more boost by going to a 175mm lower and 60mm upper pulley combo given that I lowered the CR ratio and raise the boost to 1bar/14.7psi but I'm just going to see how much 10psi on a 100oct map can get me first. I have to say that I'm still a little dissapointed right now that I could not even hit 500rwhp yet but at least DynoComp overcame the MAF restriction through larger injectors, custom TB inlet and custom tuning.

I believe you are referring to money-one, he swapped a 55k motor into his C43 but as far as I could tell it was a real headache.

Well, in the C63, it's a vastly superior motor that's intentionally factory detuned. There wasn't any need to detune the N/A M113 in the C55, as its inherent output matched the design objective for that vehicle/chassis. That's why tune-only yields such strong gains for C63s. There're logical reasons why tunes work better for the C63 vs. the C55... it's not crazy.

Latest Update
They got the torque number up to 520rwtq on the 91 Octane tune. They are still cleaning up the 91 map before moving to the 100 map.
If all goes well...I will raise the boost from 10psi to 14psi.

What are you hoping the WHP to be. I'm guessing with 520 rwtq, you should be at around 450+ whp?
I've been following your threads for a while now. At first I was skeptical about what you were doing because of the lack of progress or proof, but come to realize that you were really vested in it and screwed over so many times. I have to commend you for never giving up and I really hope that your car comes out exactly like you want it to. I'm sure it will be a beast when it's all said and done.

Thanks for your support. I really want C55 owners like myself know that this model has great perf modding potential at a reasonable cost after not repeating my trials and errors. If this project ultimately yields over 500rwhp then a used SC kit and high boost pullies that yields great power while maintaining daily drivability can be affordable also.
If I had left the compression ratio at 11:1 stock, I truly believe I would already be at 500rwhp already but it would not be safe in the long run at all once I dial up the boost past 10psi.

You are close. 465rwhp. It is very strange that torque is so high relative to rwhp. Usually on C32s and E55s the rwhp and torque numbers are always close to 1 to 1. Don't know why all that torque cannot be converted into rwhp. Hooley's C55 with the E55 blower had 479rwhp and 580rwtq. Neither Hooley's nor my torque numbers were a spike since the torque curve is gradual throughout the RPM/speed range.

Congrats on the progress you have made. I know it has been a long fought battle. Hopefully there are still some more HP on the table for you to squeeze out of her...

I've heard from Kleemann and also spoken to BlkBnzz and others who have the 113 SC'd and they all seem to advise that 10 psi is ok for a "stock" engine. Like AMG SC says, its above that where the issues are. The stock Kleemann SC installed in the C55 pumps out about 5-7 psi and can go to about 10-11 with a smaller pulley. Mine ranges , depending on the fuel and the dyno between 5-7 psi. The biggest issue is the MAF seems to not like high boost on our cars and also fuel delivery. If anyone knows of a smaller pulley available for my Kleemann and has one to sell, let me know in a PM please. I'd like to go to 10 where Alumar's was before he sold his car.
