C63 Edition 507 Build
 

I thought I'd share my build on the C63 Coupe Edition 507 of mine. My goal is to squeeze as much power and tq, while retaining the normal street look. Nothing too too crazy.

Soo far, performance/engine wise, these are the modifications complete:

-Eurocharged ECU Tune
-Eurocharged Ported and Polished Heads
-Weistec Oil Separator
-Weistec Air Filter
-ROW Airbox
-JL Motoring Carbon Intake
-Modern horsepower (ARH) Longtube Headers

Next, as we speak, my car is getting done the Weistec Transmission Build at Eurocharged Canada.

Hoping to do race cams next, but we'll see as the $$$$$$ rolls in.

P.S. The dyno run was on the EC dyno dynamics version. I have yet to test her on their new dynojet.

Sounds like a beast... good #'s. Did you dyno before/after with the p&p heads?

Yes, I believe my dyno run with ecu tune, and longtube headers showed around 430-440 whp (can't remember now).

I think he was asking what the P&P heads dynoed gains were. I'm guessing 10whp? Odd choice to do those at your stage versus some other easier and better bang-for-the-buck mods. Any reason for that - did the heads have to come off anyway for something?

nice port job :)

Nice build! Have you hit the drag strip at all?

The gains were roughly 40 whp. But then agin..it was done on a dyno dynamics dyno.

Yes at the track I've done 12.1 at 198 kph. I have yet to test the car out with P&P. I ran normal summer tires and being a newbie, had a bad reaction time when I ha headers and ecu tune only.

You should come to st thomas this friday. It's a private rental. Hopefully the weather holds up.

oh I'd love to. I just moved to sioux lookout for work (middle of no where)..it'll be a while till i can do car things....bleh.

Sigh

Ok. Maybe English isn't your language, or I'm not explaining well enough? The questions meant to ask: WHAT WERE THE HP GAIN FROM THE P&P ALONE, BY ITSELF, ONLY THE P&P, NOT ANYTHING ELSE, NOT EVERYTHING COMBINED, DID YOU DYNO BEFORE AND AFTER THE P&P TO DETERMINE WHAT THE GAINS WERE FROM THE P&P ALONE ALL BY ITSELF.

:smash:

You know what forget it I don't care nevermind

I mean he did say 40wheel

PP won't make much of a difference unless less heads don't flow well but will move the power band to the left.

There is zero way that P&P makes 40whp. That's why I clarified because clearly he was talking about overall gains from everything, and not answering the two people who asked if he had dynoed the gains from the P&P alone. Whatever I stopped caring about an hour ago forget it.

In a previous post he stated that he made 443 whp with the arh longtubes and eurocharged tune. After the p and p heads he made 487 whp. Wether or not the heads are worth 44 whp as a stand alone mod, doubtful, but maybe conditions were different and some fine tuning took place at eurocharged to gain the net result over his first pulls....

Did the ported heads make a difference in power?

:confused::confused:.....the same question I asked up top....

They made 40hp difference LOL

His already explained it above Weistec quote the same figures and 70hp with blower

He made 40+WHP with the Port and Polish alone. This is on Eurocharged Canada's Dyno. Same dyno I ran all my base lines and subsequent dyno's. Its legit.

I'm not sure how someone can say 40WHP is impossible to make when they have not had any experience with it on the M156. The numbers are legit.

Right. Okay. Find me another instance on another NA engine - any engine - where a light port and polish (because that's what it looks like, a minor polish and port matching) like that makes even half what this guy claims to have made. Just one instance. I mean, comeon, please, just read up on this stuff. With an otherwise stock internaled engine (cams, valves, etc), ported and polished heads are just not going to make a lot of power. We already know the heads flow enough for well over 900hp, what benefit is this going to give on someone not even pushing 550?

AMG heads are known to already flow pretty damn well. If the dyno wasn't done on the same day, same conditions, same mods as before, then I call rubbish. Maybe I'm a little wrong, but I'm not completely. 10whp even 15whp I'd believe. Not 40. Not ever.

I swear, between this and the magic spacers...

IIRC Dads made about 20 whp with the MHP heads and cams.

Found it: https://mbworld.org/forums/c63-amg-w...ml#post3771052

That looks like about 7whp if he was at 455 before.

According to their posts they are SAE corrected numbers (although there was some additional variance of +/-5% from run to run possibly due to operator error).

Even the very best case scenario with the MHP "race" ported heads, they "think" they might have been good for about 20whp (impossible to tell exactly as there were other changes made as well). And that's on the most heavily modified (i.e. the highest flowing, which means it would see the most benefit from this) NA C63 there has ever been.

Blkrokt, you're beating a dead horse man. The OP is simply sharing his build no need to try to discredit him.

I don't mean to discredit anyone here - it's not personal. It's just that dyno numbers are thrown around here so flippantly lately, with everyone chasing numbers, and when one of them doesn't make sense I question why. I'm a customer of EC also, so I have no interest in making them look bad either. I think I'm an equal-opportunity questioner.

My point is that if ported and polished heads actually produced 40whp, I (among others)would be sending my heads out for it this afternoon. And as far as I can tell, very few have. Including the high hp guys.

Even Kriston who is chasing the 500whp mark in his NA car hasn't done it. And he's demonstrated that he's pretty determined to hit that mark by whatever means necessary.

No offense meant at all to the OP, I'm just curious why these results are so abnormally high.

.

this is my stock head

looks like they have done a pretty big port job when looking at them

That's what I'm talking about. From the factory, the heads are already pretty well optimized. There's not a lot of room for improvement with just a port and polish job.

I went and seen higgings heads when i had my heads off as i was looking at porting them

When the guy looked at my heads he nearly had a hard attack

He compared my heads to LS heads and he said these are the biggest ports his ever seen on a stock car he said he could port them but i had to wait 3 3months i grabbed my heads and went on my merry way back to the shop to give them a clean and put them back on

i will eventually do my heads and i will report back on gains and dyno charts but not anytime in the next 3 months

i would like to see the dyno sheets to confirm 40hp

its not that i dont believe it but confirmation would be great

I sourced some heads from Dime racing for a customer i will post up some pics soon

I'd be curious as to what the actual dyno gains were with the LT headers and tune.

My gains at EC in Houston on my 507 from just the V5 tune were 17 whp (427.6 to 444.85) with a 13 gain in torque.

Added ROW boxes after but haven't found the time to see the additional gain, I'm guessing maybe 10 whp, so think I'm around 455 whp now.

My C63 sedan is decade 1 - October build. I was thinking end of Nov delivery. Reading this thread gives me hope of a early to mid Nov pick up.

What are you talking about? Sounds like you should be in the W205 forum...in a conpletely unrelated thread. :nix:

My english was the issue apparently? That's funny. Should have read more carefully.

Yes, it showed about a 40whp jump after the p&p. Even I had my head scratching to see if it made sense. But it is what it is.

I'll find out better what the actual number is hopefully in few weeks on their new dyno.

I actually did feel a little more pull at higher speeds, and pulls hard, after the ecu recalibration.

No, it was my reading comprehension problem. My bad, I shouldn't have said that. I was a bit on tilt that day.

The number still doesn't jive IMO, but whatever. As long as you're happy with it that's all that matters.
