I've been playing again. I decided to redo the works with some wild ideas that I have studied and set in motion.

This is how I've enjoyed it for the last year. In case anyone missed it, I've added the links. https://mbworld.org/forums/clk55-amg-clk63-amg-w208-w209/167426-project-chrome-dome.html


Then I've added a actual closed CLK 320 factory airbox with a K&N flat panel for testing purposes. The complete factory look without the dual snorkel AMG 55 box.





Well the Chrome Dome manifold is on the floor again. I am exploring my new idea for a hot air intake. I've been cutting and grinding and it's getting there!






Here's the sneak preview. Watch out brother, she's gonna blow

Rich,
You are my hero!!!

You put a AMG supercharger on a CLK55? Does it work? For the intake tubing just take the CLK55 intake runner and cut it in half. Do the same for the E55 intake runner. Then attach the two using a Samco or similar hose. Nice work! I heard the tuning is very difficult when putting an amg supercharger on a n/a amg motor. The s/c clutch may also pose a problem. Good luck

I've studied this over a year, real hard for the last year. It is not for the faint of heart. No it's not running yet as I have a few more custom pieces to fab, but the hurdles are being jumped, and it's coming together ,,, fast. But man it will be sweet. It will have some special tricks that you just don't get elsewhere. It will have a full size heat exchanger too. I will have to do some tuning to get it right though.

WOW sick idea. I'm really interested to see how it plays out. Make sure to keep us posted!!

Rich I'm Speechless.

jangy

Friggin awesome!! What's the ballpark price of that SC? Would a full on 55K swap fit in there? I've heard about $20 - $25 from wrecked E55s?

Good to meet another envelope pusher!! Your wheel is on the way.

mbenzman

Depends on where you pick it up from and what other parts you manage to get from the donor. There is no drop in solution and right now I'm doing a custom thermostat housing. It's a lot tighter a fit to squeeze the double belt drive and all into the CLK. You won't drop a Kompressor engine straight in either, mounts/arms, oil pans, egr, thermostat, front covers, etc.. Just to rain on my self thought up idea, Chappy came in on Friday & mentioned this has been done before to a 208 CLK55 by a member here going by the name "Dan ****". Well I looked it up and here's a link and a couple pics from his.
Anyway it should still be cool when running, This week if I have my way.

Here's a link to him talking about it.

mbenzman

Well it's been a hard couple of weeks , lots of cutting, welding, splicing and reengineering to make every thing fit and work the way I wanted. It's ALIVE
I started it tonight and the first couple drives were horrible, but the tuning is going very well and after it went sideways from a roll, I believe I have created a real monster. Then my radiator hose blew and ended the fun I was just starting to enjoy. At least the wheel I purchased from jangy showed up earlier so I could drive the other Kompressor home. Thanks.

ProjectC55

I envy you Bro!!!!

blackbenzz

You are the man! How much boost are you running or planning on running?

Ghostrider

Now that's nice!!!

mbenzman

Like you would, when in Rome, do as the Romans! As much as I can, and too much is just about right. I can switch it on and off too. Can you say "Go Baby Go"?
That AMG blower is in good company under that hood, iridium plugs, high flow seperate i/c circuit with a real pressure cap/reservoir, engine full of evans coolant and cool thermostat, and phenolic blower intake spacers to name a few items of interest. It's wagging it's tail all over the block.It's a blast! Using VP race gas for tuning insurance right now.
Don't envy me, just send me your toy to mod.

Thanks.

NitrogenBalance

No boost gauge set up? I'm curious how much boost your making. That is so impressive! Nice work

gregc

How are you tuning the car?

Split Second MAF/Timing adjustment along with FMU? Chip?

One thing I found is that the ECU will set the MAP sensor error if you run boost for a while. You will see with a Check Engine light at some point.

Unless you are playing with the ECU you will need to handle this.

I used a 2.9V Zenor Diode to clamp the voltage. 2.9V allows for about any altitude, but keeps low enough so that the ECU does not think the sensor is bad.


I am now working on a DAQ unit to watch for detonation. I have the Mercedes profiles.

rlee02135

amazing!

mbenzman

There are different ways to skin the cat. I am using the stock fuel pump, E55K injectors, the map is currently seeing boost. I am tweeking with sds and a few tricks. Amazingly, the fuel is on the fat side but within control and I'm sneaking up on full boost, currently pushing 8 psi. The torque is absolutely amazing, maybe the 2.82 gears make a big difference over the 2.65's in the E55K.

I haven't cruised down the road yet, just down the block. I'm not calling this done yet!
Greg, you have a completely different setup from mine. For instance the pcv hoses I hook up with factory parts for the Kompressor setup. My throttle body is still about in the same place, and the tank ventilation and brake booster line hook right up using the Kompressor parts (no the w211 doesn't have vacuum brakes but the hookup is there ) . Only custom parts on top are the air intake and egr setup.
I also have the factory intercooler functional and it's hopped up. I have some options on tuning if the need arises. I am not running a fmu as with the larger injectors I haven't had a lean problem, I've been removing fuel.
I haven't had any detonation, but I have a load of ultra high octane vp race gas to prevent it while I check the tune. I appreciate the input and love what you've done with yours and will take note of any advice. Thanks.

blackbenzz

So you are using 55k injectors without a problem? I was told its not possible on our CLK55's without extensive ECU tuning

So if the romans were to put a number on how much boost you are running, what woud that number be? Great work, i'm really impressed If I could I'd run 20PSI, but the limits havent been tested yet. I think I'm going to bump it up to about 8.5-9 PSI shortly.

mbenzman

I have only seen 8 psi as I mentioned earlier.
I do reserve the right to change directions, and I haven't said I'm done or this is the way to go yet. If it doesn't work out the way I want, I can see if a custom tune can be dropped on the ecu, or drop the normal clk55 injectors back in, a fmu and do it the Kleemann way or the split second unit may be the way to go. I'm not there yet. I can also lower the boost on this by bleeding off the boost at the bypass.

Your boost limitation is going to be set by your belt. It will not take the strain. You will have to improve your belt drive, ask Ted Baldwin about belts. we are going to build him a new belt drive.

gregc

I am surprised the fuel pressure is flat. Mine fell like a rock, but that is somewhat a result of increased fuel pressure. Look the forums as I did find several pumps if you need to update.

With larger injectors over stock, the closed loop control will adjust. It is open loop that may see strange things. Most of the tables run off the Load calc. With larger injectors, the load calc is off and high. May not be a problem, but will affect those switches from closed to open loop as you go up hills.

Watch out for tip-in detonation. I had all kinds of probelms with this on the roots blown mustang I played with for a while.

It will be great to see the car on the dyno.

My powerdyne is the limit today, as its out of air flow. These 5.5L like lots of air flow. I see max 7.5-8psi. A company just came out with a new turbine, which I plan to install. I would like to see 9-9.5 psi max.

With these 11:1 compression engines we are pushing it when above about 8psi. If you go above 8 you may want to sup with a meth injection to up the relative octane.

keep us all informed. I have though a lot about jumping is the same way you did with the screww setup. Would be a fun winter project.

mbenzman

This is a dyno from my E55 done on Sat afternoon. Notice it's run 6 and 7, where's the heat soak? Nice numbers for stock.

mbenzman

Get scared, we are at 12 psi and yet to go full throttle. Esp off and 40 mph spinning tires with the quaife is fun.

blackbenzz

Holy ****! Make me one!!!!

mbenzman

It's not all roses right now, I am going lean now, so it's not safe at all. If I had to I would have to reduce the boost, which I can do, but don't want to. The intercooler is holding the air temp. down, the cool thermostat and evans coolant are doing a great jobs holding back the detonation monsters, but going lean is not an option, at 12 psi I'm more than a little nervous. I probably will install water injection just for insurance.
For my current leaning out problem, I'm thinking one of three possible directions, piggyback controller, I like the Apexi Neo, a FMU, or a complete retune, which is my preferred route right now unless forced back to the other two. I will hold right now while I am exploring this option. Here's an interesting little bit. In all the ecu exploring I've been doing, I found some menu items. It appears than M.B. had their options open by 2002 as far as possible combinations. The 2002 CLK55 ecu has the supercharger and intercooler pump control references in it including the actuations feedback. See where and why I'm heading here. Time to make some calls and maybe I'll be doing a little rewiring if I can find a little ecu program adjustment for the complete Kompressor program in a 208 ecu. I would love to lose the maf like the kompressors.
In the meantime it is finally drivable (albeit with esp blinking ) if I don't try to floor it, which like the E55K, I never have to go WOT to get my ear to ear grin everytime.

Gregg, you might rethink your not allowing the map to see boost. Mine seems to like it a whole lot better than just giving it a vacuum reference. It wanted to ping without seeing the boost, but it was a still a little too lean at that point.
BTW the fuel pump in the CLK55 is the same used on the G55 Kompressor. It has no boost or even just vacuum referenced regulator or other monkey buisness. They must just compensate for boost with injection pulse width. That's why I have tried to stay with the factory recipe, at least til roadblocks force a change. There ARE modded G55's around pushing 650 HP without starvation issues. As a matter of fact, you would be shocked at how fast A 650 hp G will drain a very large tank of 93.
So what fuel pump did you use? Specs?
