Also my eisenmann race exhaust should be here soon

That's right ! But this is not to mean any disrespect to DEREK at all. Derek has been the standard.
Malcolm told me he's building a CLS55 now and it's gonna be sic. Right now he has the fastest E55k known in the country:10.4 sec @ 142mph in the 1/4 mile. I've known Malcolm since the early to mid 90's. I remeber his modded ACURA NSX! He's also been in many mags ,Sports compact magazine,Turbo Magazine just to name a few.
Keep up the good work Ahmad!
PS the heat exchanger on your stck CLK55 bumper ddoes not look that bad. But after all this is a pic.
Try the Carlsson bumper u have.For Ahmad ALL MOTOR NO NOS! mid to low 11's Keep everyone posted. I believe you'll achieve it.Good job Bro. Hope to see the BEAST soon.

Placing your hand on the compressor is not a bad test, but time at the track will tell if this the weak link in the Kleemann system. Please keep us posted.

. Trust me, the numbers are there
Maybe not low 11's but I think I may get kicked out the next time I run at the track and I think traps will be 120+! The baseline time to beat for my car is 11.7 @ 118.9 One other place that I think a major improvement can be made is the intake runner openings at the front of the car. They are so small! I'm just worried that if I make bigger inlets I may suck in small woodland creatures

Carl- Thanks for the kind words.
Neilbo75- Going down in boost is NOT an option, only way I'd go is up. There is very little heat as of right now. I'd even go so far as to say it runs cooler than my CLK430! I'm not joking about being able to put my hand on the s/c after running it hard. Its barely warm to the touch.

The Best of Mercedes & AMG
My point is that the stock Kleemann set up is prone to heat soak. There seem to be two solutions : get a much bigger heat exchanger like Blackbenzz is doing or reduce boost.
Reducing boost IS an option, since Kleemann can change the pulley size. Going down to .35 bar or 5 pounds still leaves an estimated 450 HP at the crank if you also add the headers. That should be enough extra power to make the 208 CLK55 faster to 100 km/h than a V12 Aston Martin (DB9 or Vanquish S, both heavier cars). That's my bench mark.
Sure, more boost means more power, and Blankbenzz's set up is sure to win at the drag strip. But it also causes more supercharger whine, more traction problems ... and more heat. This heat exchanger is a great mod but I would also add an oil temp gauge to better monitor temperatures inside the motor.

Blackbenzz : IIRC when your car was Learso's he already had the exhaust moded? I seem to remember a post where he was asking how far out from the bumpers the chrome tips should be.
And funny thing about the S/C whine -- most people report it to be on the mild side but in your recent video of the drags it comes across the tarmac like a police siren. I gather it's more noticeable if one is outside the car.

I'm not upping the boost YET. I'm going to look into port and polish heads first. I was going to up the boost to 10 PSI the firts month I got it
Now that I have made several 11s passes (was expecting a best of 12.2 based on other peoples runs) I am content and a little more sane.I've heard Malcolm's FMIC adds 40-50whp. I dont doubt it. If I was to gain a similar result I expect to be sub 11.5 and after the heads I may not be allowed at the track anymore
The 55k motors are lower compression and built for boost. I think 7PSI is very safe and conservative. May strap on a bottle like DerekFSU did for a few passes (try to get the 208 into the 10's)and then never use it again. Only time and the thickness of my pockets will tell.

Whatever it is, you and this Malcolm guy are defintiely on to something. Am I right you broke the twelve second barrier without drag radials?
Do us wannabes a favor and don't port and polish until after you have track tested the heat exchanger mod. We are using your car as a guinea pig to see what mods work best and if you combine too many mods at once the results get blurred.
I am now wondering, if I go with the Kleemann set up should I pester them for a bigger heat exchanger? However it has to fit the stock 208 AMG bumper. Could a larger one have fit in there?
The Ford Cobra GT500 is a boon for gaining F/I tuning info and maybe scoring some deals on parts. The motor is almost the identical size to our 55s albeit with an iron block and DOHC. In fact, the whole car is similar in size : "compact" adults can actually fit in the back, unlike Corvettes or Vipers. In a recent Motor Trend test, the 500 HP Mustang predictably could not match the Z06 or Viper in ultimate performance but the editors ranked it second on account of its practicality and terrific value for money - $45K list price. Ouch, we Benz owners had better cultivate the refinement side of our rides. It the Kleemann blower really is quiet inside the cabin, that's a good start. The GT500 got criticized for its "AM radio" supercharger whine (8.5 pounds boost).
I did run an 11.7 on Toyo RA1's.
I dont know about waiting on the port and polish, winter is downtime and perfect opportunity to get it done. Plus its not like I just go to the track, make one pass, and get my best time. Even the smallest modification and I have to relearn how to launch the car.
Kleemann wont give you a bigger heat exchanger but you can get one made to fit behind the OEM bumper thats bigger than Kleemanns ( I will be gettiing a custom one eventually).
The Kleemann really is quiet from inside the cabin. I try really hard to hear the whine but I dont. You can hear the air rushing in though, kinda like a vacuum cleaner lol!
I was going to go with Michelin PS2s when changing to 18 inch wheels but damn the Toyos are cheaper and also come recommended by Kleemann. Any drawbacks?
11.7--on street tires! You da Man. Kleemann LSD helps on the launch but it's clear you have exceptional driving skill. And sure, practice makes perfect.

) I actually have PS2's sitting in my basement because I wanted more grip (they will go back on for the winter even though the 55 probably wont go anywhere). The RA1's are alot stickier than the PS2's and you can drive on them daily (I do). I highly recommend them. They arent cheap and dont come in many different sizes. I'm running 275/35(?)/18 Hope that helps.
