You didn't by any chance do a before and after dyno of pre and post high flow secondaires did you?

betrezra

No sorry no dyno data pre-post exhaust N/A.
Seat-o-pants seemed better, but you know how that goes.

Nachtsturm

Just wondering if it is worth the hassle, if it is worth a good 10-15whp I would do it. Just haven't found much info on it.

I say a thread that AMS said replacing the secondaire with hi-flows is worth that, can't seem to find it again.

betrezra

Yeah that is the thread where 1st mods began.... AMG shorty headers, hi flo 2ndary cats, and tune.

If I were to stick 100% N/A and try to dip deep into the 12's..... I'd have test pipes made for the 2ndary cats, you can bolt-in, take out. heck I'd have a custom off-road x-pipe from the headers to the catback with no cats for that matter... Bolt-on, then get a tune for the offroad, exhaust. Sticky tires and get after it.

Nachtsturm

Found it!

https://mbworld.org/forums/w210-amg/...lete-give.html

10whp for high flow secondaires on a M113 in a W210 E55, and looks like hooleyboy picked up 13whp/19wtq from deleting the secondaries.

Seems the X-pipe helped abit as well. I will have to talk to a shop to see what can be fabbed. An extra 15whp would be superb. Really don't want the car any louder than it is so it will most likely have HFCs.

In my experience on other cars going completely catless is only worth 1-2whp.

Deep 12's sure would be nice though, but I'll be content with 12.999@110.00

Laptop arrived today. Multiplex/cd next week, then time to diagnose with STAR.

12.18.11 Update:

* I tried adjusting the FMU to elim the LTFT's going up after cruising. I got LTFT's down to 15/16. Still too lean for me.

* Starting inspecting things and found header nuts loose, and one missing on the bank 1 side. Aha! That will make the bank 1 o2 sensor uphappy.

* As long as I was down there, I pulled the plugs and they are fouled, I suspect unhappy with the bad O2 affects on the tuning. So new plugs on order.

The plugs in it are Bosch Super R6 988 gapped at .032".

Is this the correct cold plug for my klee application?

Someone please LMK what plugs you're running in your klee clk55's.

Thanks BBenz!

Gap for a 03 W-209 5.5 AMG is .031 . I used Champion # 9001 . Gapped a little tighter .028. So it doesn't jump down the side of the insulator do to the much higher combustion chamber pressure , VIA the blower . 9001 is a 1/2 heat range colder .

Thanks PTE.
Plugs, ex nuts on order.


Do Klee headers just use stock MB ex gaskets?

blackbenzz

Too bad you're not local, you could have just swung by my house and picked everything up lol. And yes stock exhaust gaskets

betrezra

If the header has been leaking..... do I need to change the exh gaskets or Just install new nuts and snug-up?

Kevwood

I believe the MB exhaust gaskets are metallic, if you don't have a urn through you shouf just be able to snug up. Not like the old days with the SBC and fiber gaskets! What a PITA those were eh?

betrezra

It kills me the dumb things that have gone wrong on this build...... there is no substitute to doing things yourself.

Kevwood

Totally agree with you there bet. So, just got word from my tuner that Kleemann has told him that my AFR curve is a-okay. It holds a nice steady 11.9 - 12.3 across the board with exception of a 4500rpm spike in which it reaches 12.9/13.0... Conventional wisdom in tuning a boosted car tells me that's too lean (thats what i used to tune my NA engines to) but apparently it's okay.

Okay or not, I'm still curious as to why it spikes and will be contacting Kleemann directly to ask the question.

Give me your thoughts.

PTE

Have your DC to DC inverter come in at a 1/2 lb boost sooner via resetting the pressure switch.
Cheers _PTEngineering

betrezra

Where is the dc inverter?

=====
*4500rpm spike 12.9-13. I would not run it that way.
I would get it sorted.

I'm getting my own STAR system and will report how that works for me.... you may want to invest in your own setup for diagnosing issues, and CHECKING your tune in the realworld.

A sloppy tuner will just tune @ WOT on the dyno in perfect conditions to give you the max hp/tq on a sheet of paper.

A good tuner will do this AND drive/monitor the car for a few days to check the state of things in the real world under all driving conditions. There is a big diff between one cooled down WOT run on a dyno..... and a heatsoaked run in 100deg F.... or part throttle runs.......... I'm convinced the part throttle/low rpm high boost instances are the risky areas for our cars.... NOT WOT. When I finally did some logging with fuelpress/boost on the street I was amazed at how this blower puts out 7-8psi at any rpm with the romp of the foot...... if your tune is not up to snuff.. you can have lean issues in areas you would not expect.

betrezra

New Header bolts installed, all other header bolts snugged up. Several were loose.
Also tightened up header collector bolts, all were loose.
Also managed to recover the tools I've lost over the last 2 days onto the bottom engine pan Glad to have those back.

Just waiting on my new plugs, then road test.

Kevwood

Hey betrezra (or anyone else reading this thread) - do you know of any monitor/logging units like your DashDaq (that have optional wideband O2 input) that has video out capability to be streamed to an in-car video system?

I'm swapping out COMAND for an aftermarket unit and I'd sure like to be able to have everything on one screen.

Cheers

betrezra

I'm running a dashdaq / Zeitronics combo.

Dashdaq data-logs from the OBDII Port giving base-line rpm.....
Zeitronics offers all the adders: wideband AFR, boost, fp, etc.....
You can link all the zeitronics data into the Dashdaq and have real-time vid display on the suction cup mount and/or record (data-log) and playback after a run.

yeah that's it.
I did not buy the bundle, I bought everything seperate.
The bundle is the way to go.
......
I used my spark plug sand-blaster cleaner tool, regapped, tighten the tips down (they were loose).
Went out for a run with all ex leaks and plugs cleaned..... and same deal LTFT's ramp up to 15/16 after about 30 mins of driving. NO CEL, but the LTFT's are too high.
So back to the drawing board.
Next week I'll pick up my star multiplexer from shardul, and get to analyzing my ecu while driving to see what's going on.

Once I get this tune figured out...... it is track time.

Hoping to join the 11sec club real soon!

Kevwood

I don't think there are any doubts you'll be joining it with the amount of RWHP you're putting down

Walter686

I hear you NO2 balance.... Motorwerks is just down the street.... but I doubt Sunil has time to mess with an E55 motor swap.

I'm leaning towards Kleeman, bigger heat exchanger and pump, my PTE cams, and fresh tune.

IF the shorty headers I just bought are holding me back, I'll swap them out for some of the fancy kleeman mid-length jobs with the downpipes
