For your purposes, install the cwa 50 and wire it so its running when the key is on. Then while staging, leave the key on engine off to cool it. Might be a good idea to coast at moderate speed and low throttle a bit before staging.
Some of the lightning guys i know actually sit a bag of ice on their supercharger while staging lol

Haha I am all about performance with my truck. I had my duramax out there and was running 13.0s. She needs more fuel now and with my turbo setup I can run high 11s on stock motor for a little while till she blows lol.
I think he wouldn't mind doing pulleys and tune later on but want to run the 12.5s most of them do first. He has pretty decent tires on it to so if we can get it out of the hole he should be low 12s I would assume.

I feel this creating a huge lag when i shift from 3rd to 1st in a passing situation. Or after sitting in stop and go traffic on a 90+ temp day.
I suspect cooling in staging will make a huge difference in your holeshot.

Hey guys new here. I have been reading for a few days and have some mods I would like some input on. The car is a 05 sl55 with 44k miles. I don't have any previous maintence records. Plans are to have it as a cruiser and drag vehicle. Here's what I'm thinking for mods.
-Johnson cm30 intercooler pump
-pulleys
-tune
Is the Johnson the best ic pump or is the new Bosch found on the later models better?
Also pulleys, do you do the 180mm crank pulley and leave the sc pulley stock? Both at same time or sc pulley only? I'm seeing a 77mm sc pulley. Is that a good route?
Who's a good tuner? All I can find is eurocharged.
I'm liking eurocharged stage 1 package. Seems like a good price for a good 100hp gain.
Sorry if these questions have been asked a million times, I read through the stickys and still had some questions after reading through them. Thanks for the help!

I've found the later Bosche pump is more than up to the task. We do crank pulleys in combination with ECU tuning.

Great thread! Thanks to m-svt-amg for all the great info!
After 12 LONG years I FINALLY got my hands on the 2004 Designo Graphite SL55 that I specked out new for my father-in-law back in 2004. He let me do a Renntech tune and crank pulley (168mm?), Renntech intercooler upgrade kit (pump & IC) and a Kleeman LSD back in 2006. The car has been great ever since, with only 53k miles on it now that it is finally mine (I found him a low mileage 2013 SL63 for less than half of sticker price and I did the Renntech tune on it for him).
I am selling my 2004 Designo Mocha CL600 Sport that has the Renntech tune (625hp/734tq) but otherwise bone stock. I know the SL55 will never come close to the torque of the V12TT, but as long as I can get the HP close to 600, the cool sounds and sporty handling should keep me entertained for a while. This is why I'd like to step it up a little bit, but without getting into changing injectors, throttle body and trunk tank.
I removed the resonators for some more sound and I honestly cannot even tell the difference, so I found a set of new in box Renntech "shorty" headers crazy cheap off ebay and plan to have a performance exhaust shop with a mandrel build me a custom center section because nobody seems to offer one. I got a low mileage 84mm clutched supercharger pulley from a fellow mbworld member to run with the existing Renntech pulley.
Does anyone have an idea what the boost will be with the Renntech (168mm?) crank pulley and a 83.7mm clutched pulley? I understand that both of these pulleys are extremely conservative by themselves, so together they should be just about right. I am hoping this combo will put me close to 15psi but not much more. I may also do the basic split cooling kit but not interested in a trunk tank.
I know that I will have to find someone to retune it as soon as soon as I install the new exhaust and SC pulley, but other than that I think I'll just let it be and enjoy.
Any thoughts or opinions are greatly appreciated!

here is a useful pulley matrix. keep in mind that which supercharger you have (#280 vs #080/580) will also help to determine your SC speed (and boost). Also, headers and other less restrictive exhausts will make your boost appear lower (while actually helping to increase the amount of air ingested : )

Having said that however, on my 2003 SL55 I was curious when the pump was and wasn't active, so I datalogged it briefly and found that it is on nearly all the time the engine is running (essentially, except when the engine is first started or when you slow to a stop and the IAT is below 80° F or so), so I left mine in the factory configuration. 2005 may be different however.

Hmm maybe I will just run it off the factory location. Is the resistor needed or can I just wire it up? Also is there a diagram somewhere showing which color goes where?
#62
MBWorld Fanatic!
Pump Connector Pinout:
Pin 1 is Common or Ground
Pin 2 is LIN-Bus
Pin 3 is PWM input signal
Pin 4 is + 12 to 16v
connect pin 1 to the brown wire in your harness
connect pins 3 and 4 to the other wire
pin 3 should, ideally, be connected thru a resistor (1000 ohms is good), but some have hooked it up directly and I've yet to hear of anyone having a failure because of this.
pin 2 can be left empty
hope that helps

Awesome so pin 1 will just be a black wire, pin 2 empty, pin 3 can be wired directly to what color? And pin 4 will be red? The factory pump connector will get cut off and have 3 wires that I can just attach to the pins and plug into the new pump?

you can use ANY wire color that pleases you ...
THESE are the car side wire colors
" connect pin 1 to the brown wire in your harness
connect pins 3 and 4 to the other wire "
the "other wire" is probably Blue with a Black stripe (red/yellow up through 05/2005)
EDIT .... I had my CWA 50 out this weekend (upgraded my 2003 SL55 to a CWA 100) and made some observations that I should include here.
To Begin ... the CWA 50 and CWA 100 have the same pin-out on their respective 4 pin connectors (the only difference is the current requirement. The CWA 50 never needs more than 5 amps and the CWA 100 humps along at about 7.35 amps after an 8.2 am start-up).
Pump Connector Pinout:
Pin 1 is Common or Ground
Pin 2 is LIN-Bus
Pin 3 is PWM input signal
Pin 4 is + 12 to 16v
The CWA 100 having the higher current requirement needs to have larger gauge wires (1.5 mm or 14 AWG preferred) and should be fused at no less than 10amps (2014 SL65 uses a 15 amp fuse), but this thread has been about the CWA 50 so I'll try and stick to that ...
for wiring in a CWA 50, you can wire directly from the 2 wire harness (that plugged into the old pump) to the new connector
Connect Pin 1 to the brown wire in your harness
leave pin 2 UNconnected
Connect Pins 3 and 4 to the "other" wire
the "other wire" is shown in the documentation as being Red/Yellow (red with yellow stripe) up through 05/2005 and Blue/Black after ... HOWEVER, in my 2003 it was RED with a WHITE stripe.
NOW, I have always suggested that pin 3 should, ideally, be connected to pin 4 thru a resistor (1000 ohms is good) ...
BUT, as I discovered this weekend (looking at Mercedes documentation for a 2014 SL65 which comes with the CWA 100 as standard equipment) Mercedes just ties pins 3 and 4 together with NO resister. SO, it's not a problem to wire it with the resistor (protects pump electronics from over-current) and according to MBZ its not a problem to wire it without the resistor. (I now have one of my cars with and one without the resistor).
hope that clears it up a little.

Do you notice this at gear shifts under WOT? I could be way off, but I know the SC belt will slip momentarily under those conditions. I was trying to find a vid that shows it happening, but could not find it. I think Shardul may have recorded it. Anyway, if that is the issue, the answer is the belt wrap kit.
