Well, as I promised this is one of the 2 new mods….the next one is awesome.

I have driven the car 20 miles and it fells different…of course quicker.

I will work the weekend to fit the air-box correctly because it needs some modifications but nothing drastic. For example, the rear support does work with the stock SL55 air box, but the front one does not much perfect. The room for the air filters is fine and it needs some minor modifications.

The engine looks bigger, and I will present a picture with the front cover as well.

Finally, I ask Ben for a good price for the evosport’s header….and I was ignored:

Thus, I will not post the 2 mod.

Thanks

Steve Clark

just as you've said,and I'm not doubting your results.However,the
dyno chart posted has a problem...the 1st run (red) shows higher torque from about 3400-3900 rpm,yet the horsepower yield is lower than the 2nd (blue) dyno run.This is not possible.

Pierre,

I apologize if you thought I was ignoring you. For the past 2 weeks, I have only been briefly scanning posts on MBWorld. I just had eye surgery, and I am waiting for my eyes to fully recover, as I currently experience dryness and headaches from staring at the computer screen. I will continue to frequent the boards over the coming weeks as I recover, but it will probably be a month until I am fully capable.

Our headers have always been priced at $1,799, except for during pre-sales which are long since over.

Thank you for your understanding.

Ben

Pierre32///AMG

it fine Ben, take care

Steve Clark.
this is another set up....I believe with just SL55-Ypipe....and it could be possible becasue that day I "dynoed" at 95 F ambient temperature.
I have not dyno the Full SL55 intake= (inlet pipes, air-boxs, filters, 2 short pipes, and Y-pipe) app. $400 total in a local dealer.

Steve Clark

the rpm band I mentioned...something's just not right with either the red torque or hp plot at those engine speeds.I agree that your intake enhancements are all good ideas...but this particular dyno comparison is weird from 3400 to 3900 rpm.

Bux

ah good idea pierre so whats the 2nd mod?!

Shine

Hi, Pierre
Good try !
Do you notice the A/F ratio fly up after 3500 rpm ?
Is that lean in high rpm zone ?

e.g A/F ratio is suppose to run under 15.

Pierre32///AMG

Steve Clark, I have no dyno my car with Full SL55 intake, just the SL55 Y-pipe help but not as much the full intake set-up.

Shine, I finished to install it...with everything in order...wasn't that difficult...my car has now 25 miles and I must say it is a completely different machine, more loud, no loss of power in all the power band and better mid & high rpms. On the highway..... just amazing. Shine, I can not get a A/f ratio reading, but I am using the SL55 stock filters; nonetheless, remember I am here in Colorado at 5,285 ft...like 1,700 mt above the sea.

I will dyno next week.

ro0zy...basically my goal is decrease the cooling temperature that goes to the IC, and I have the solution, no more water because it keep longer but it take longer to cool it down. .... one member and personality of the forum is helping me

IC reservoir Thermo-isolation

http://groups.msn.com/Mercedes2003C3...oto&PhotoID=45
simple, as you may see this mod is obvious, look how close the headers are from the IC reservoir...when the headers get operation temperature that region gets really warm; thus, if there is a way to thermo-protect the IC reservoir for external high temperature sources, this is one.

SL55 vs. C32 air-box panoramic few

http://groups.msn.com/Mercedes2003C3...oto&PhotoID=46
It is clear bigger the SL55 (left) air-box
another shot
http://groups.msn.com/Mercedes2003C3...oto&PhotoID=47

different inlet

http://groups.msn.com/Mercedes2003C3...oto&PhotoID=48
well, with just the SL55 Y-pipe you get an extra air volume at the intake region, now when this air is used the stock C32 air-box just feed air that region with stock capabilities. Now the SL55 air-box does feed that region gently. Steve Clark, perhaps that was the reson because with just the SL55 Y-pipe I got within 3400 to 3900 rpm higher torque and hp....after those engine speeds the stock C32 air-box does not feed with sufficient air the Y-pipe..this is my theory, dyno will confirm.

finally, of course I Thermo-isolated the SL55 Airbox, and the engine after everything installed looks massive.

Ciao!

Pierre,

Have you or others that installed the SL55 "Y" noticed how the hoses now rub several clips on the firewall. Especially the drivers side. Have you done anything about this, and are you afraid it might wear thru or tear the hose?

Pierre32///AMG

yes, it is just one "the drivers side"....and I removed it and installed below...cleaning up that area...this is a good recomendation...

Pierre:

Do you have a part number for the box and the inlet pipe, does the inlet pipe fit straight up to the front of the car? Can you discribe in more detail on the mod that you need to make for the "foward feet" under the SL airbox?

Thanks and keep us posted when you have the new dyno with the complete setup.

AlpharettaC32

This is exactly my question. There was a previous note that the forward clamp of the V8 airbox did not align with the footing on the V6 engine. How was this issue addressed?

Pierre32///AMG

Tomorrow 10:00 am, I have appointment at the dyno.

You are right, V8 airbox did not align with the footing on the V6 engine… but the solution is very simple:

http://groups.msn.com/Mercedes2003C3...oto&PhotoID=49

The rear supports do much doing a little room, but for the front ones I used the metallic support of the C32 airbox to relocate and align the V8 box in a V6 engine. My philosophy of operation is always use MB material, for quality and consistency.

The passenger side airbox is really easy to install, just a few modifications. The driver’s one needs a little more job, but nothing crazy…..I will post installation after dyno hopefully this week.
some photos of some modifications:

Part # (I got the ones in stock in the US, you may order it to germany):

113-094-16-82 (Hose) Inlet1 $11.81
113-094-17-82 (Hose) Inlet2 same
113-090-06-01 (airbox1 with filter) $147.6
113-090-05-01 (airbox2 with filter) $147.6

how does fit passenger side:

Why are you calling the Radiator Reservior an intercooler reservior? Did you modify the intercooler plumbing? If not insulating the Radiator Reservior will do nothing.

Pierre32///AMG

Zeppelin, based in this picture:
http://groups.msn.com/Mercedes2003C3...oto&PhotoID=53

I believe that is the same reservior, please correct me if I am not right.

thanks

Zeppelin

Pierre,

You are right that the intercooler reservior and the radiator reservior are the same on a stock car. The reason I say insulating it will do nothing is because the radiator is dumping hot coolant into the reservior. It might help until the car gets warmed up, but after that it will do nothing.

Bux

ya it would be better if ic and radiator were seperate

Pierre32///AMG

both of you guys are right......I am just comming back from the Dyno with big ....... the SL55 airbox + inlets give me 9.5 rwhp and 4.2 rwtq ...... no bad for $330
I am working in my post....it will be in 15 minutes

Ciao

auxo

Pierre,

Is it possible to show me a picture of how you "cleaned up" the area? That one clip on the drivers side that rubs against the SL55 hose does concern me.

If it is difficult, please disregard.

Thanks!!

Pierre32///AMG

No so easy, 20 sg...!
I may have to remove, and re-install everything, but I can tell you what I have done.
http://groups.msn.com/Mercedes2003C3...oto&PhotoID=58
I took a screw driver with a * T-25 and removed that one clip (See photo), which rubs against the SL55 hose…
http://groups.msn.com/Mercedes2003C3...oto&PhotoID=59
..and I just installed “occulted” at the same place but beneath the metallic lamina that was originally adjusted ….that it. This is a MUST for everybody that is doing the SL55 Y-pipe set-up.

Now, for people that are going to go for the Full-SL55 intake, there is an additional modification on the engines “room”, which is the relocation of this cable at the driver side:

well this is a view of all the Full SL55 intake intalled:

Thanks Pierre,

That was most responsive and kind of you to post pictures and even procedures.

I will do that tonight.

Thanks again!

box986

I did my full SL55 intake mod, big thanks to Pierre for the detail tips and pictures.

First impression after the install, lower and more agressive intake sound at low to mid speeds plus better throttle response at all times. It totally change the character of the car, it opens up the car's high end acceleration even more.

I easily out-ran a 993 C4s from about 60 to 120mph last night.

My performance mods so far are Evosports ODPS, removed resonator and secondary cat, full SL55 intake.
