Needed just a little color break-up from the oceans of white and black....







....I'm going to hit the calipers this weekend and call it done.

solekeeper

that is interesting. neat job.

C63-AMG

looks good.. Is it high temp paint?

jptaylor

Dupli-color Engine Enamel....no clear coat, it tends to yellow with the heat

AMG893

Yeah, dont put a clear. It does yellow a bit with the heat.

I did my calipers same blue. have done on most my cars. did one with clear coat, and looked bad after a while.

Nice job!

abcut973

That is one of the kind.
Looks like a pro. Great job

jptaylor

Thanks, and I'm partial to the blue....my silver srt grand cherokee I used the same color blue and loved it....its just different.....I think that too much color is a BAD thing, but a tasteful amount can be just right.....BTW, I think that a red C63 with matching intake and black AMG lettering would be FI-YAH!!!

jptaylor

Also, if it looks a little less cluttered than others you're right....I HATED that muffler/bellows/resonance chamber between the intake tracts that sat on top of the manifold-so I got rid of it....15min with a Dremel and some gloss black paint and much more sanitary look.....I just plugged the vacuum line and secured it behind the intake inlet and have noticed ZERO effect on anything whatsoever

Just an FYI - I looked through WIS/EPC to try and figure this out myself, since I wanted to make a new bigger Y-pipe (still might). That "box" you removed is a pressure reservoir, and may be for the brakes as far as I can tell. The brake pressure reservoir is an accumulator that provides spare hydraulic power to the brakes, and removing this may stress your braking components unnecessarily. This is clearly just air... but I can't figure it out. I don't know if it's worth removing, because I like my brakes working just like they are now. Just beware.

That's interesting if it's for the brakes...I asked 3 separate shops what it's actual purpose was and all 3 said it was a silencer so the intake would meet M-B noise level requirements.... If you follow the line back it just Ts into another manifold vacuum line. Also, when I got the box off I checked to see if the inlet was a check valve or just a nipple, and its just a nipple....I have not tried any emergency type stops but I will....haven't noticed any difference in regular braking but I WILL do some more digging and I DO appreciate the heads up Brother!!!

If I do find that it's related I will add a remote reservoir box somewhere less intrusive.

How does pressure in the intake help the brakes? Brake booster works on vacuum from the engine and intake. I don't have that on my car and neither does any blower car and the brakes are functioning perfectly fine. Don't think Weistec would remove anything that helps the braking system.

BLKROKT

I couldn't make a determination for sure, so I just left it alone. WIS/EPC says "pressure reservoir". and the only parts on recent MBs that fit that description, are related to the brakes. I followed that hose too (which by the way says "to vacuum reservoir" - the box), and yes it "Ts" off into the intake manifold, but then comes out underneath and goes who knows where. I didn't know enough to mess with it to take it off, otherwise it would be gone.

It's not a silencer, I can tell you that much. Doesn't make sense for that part to lower noise, as it's not connected to any part of the intake, and doesn't have any muffling attributes. I'm pretty 100% sure it's not that, but whether it's important or not is a whole other question. It is a pressure/vacuum reservoir, but for what...

BLKROKT

I haven't seen "pressure reservoir" used anywhere but in conjunction with brakes, and that was good enough for me not to mess with it until I had time to figure it out. Whether that is hydraulic or otherwise (this is clearly just air), I'm still looking at. This could just be a brake assist, or could be nothing. But it makes no sense for it to be an intake muffler.

But if I don't know what it does, I've learned by now not to take it off until I do.

BLKROKT

And I know Weistec knows what they're doing.

Do you think Renntech does? (see the box)

AMG6.3

Looks really nice man! Good job.

Old thread but since I'm here I figured I'd share for prosperity...

The vacuum reservoir (Black box on 1560900329 intake tube, separate part bolted on crankcase for 2007ish engines) is simply a sealed volume to store vacuum created by the intake. It's purpose is to provide vacuum to vacuum actuators (eg. Intake length switch over valve) when there is no intake vacuum (WOT or engine off). There is a check valve on the hose going to the intake which prevents vacuum from being lost under these condition.
It has no effect on intake sound or brakes, removal is not catastrophic but will impact behavior of actuators which will lead to inconsistent performance.

BLKROKT

Interesting, thanks for clearing that up. Do you know how the removal of that will impact performance? I assume blower cars can get away with removing as they replace the intake manifold altogether. I wonder how taking that off would impact the performance of the runner actuators? Anyway, doesn't sound like a good idea so glad I didn't chop it up.

jptaylor

I have had mine off for about a year and a half and have noticed NO difference whatsoever...

VII

The first thing that comes to mind is you are stopped at idle and quickly go WOT with the aim of getting a ticket. The intake should switch to short once you are at around 4k rpm to maximize top end power but since you are at WOT there would be no vacuum and the intake will not change until you reduce some throttle.
Not to worry though you'll still get that ticket.

VII

It is even possible that there is enough vacuum on the lines to provide actuation under some conditions, you know how somethings are overly engineered when it comes to MB and others under....

jptaylor

I don't doubt that scenario on paper but I honestly can't tell, hell I can't get any traction from a dig anyway without feathering it and I was running 285 M/T Street Comps

BLKROKT

That would be particularly no bueno at the dragstrip where you're idling waiting for the lights.

Would you throw a code if the actuators stopped... actuating due to this?

jptaylor

Question? Do you launch at idle or do you brake torque it to aroind 1500-1800?

I am going to throw a spare vacuum canister I have back in line and see if I can tell a difference going the OTHER way

BLKROKT

I'm at idle until the first light comes on. Then I floor it while on the brake for about a second, then I go.

Will be interesting to hear your results.
