Ted, you get yours back yet? I'm anxious to see how she performs with your new mods, and a list of the mods for that matter.

I just got mine back and I'm in love with my G55 all over again, like a kid with a new toy. For those not following, over the past two weeks I've had a mixture of Kleemann parts installed on my 2005 G55 Grand Edition, using some portions of stage 3 and stage 4. The work was done by Chris and crew at C2 Design in Tampa: http://www.c2dusa.com/ They do a lot of Kleemann work as well as tuning of other vehicles. You have to look at their site in IE though because it doesn't work correctly in FireFox. (They know this, I gave them a hard time about it) They were very good to work with, kept me in the loop on everything, and I even left a digital camera with the truck and asked that they take pics for me as things came on and off so that I could put together a nice review of everything and they responded by taking over 150 pictures for me, I almost expected to see the wrenches and screw drivers they used. LOL When the vehicle came back, I put about 50 miles on it and then got a check engine light; it seemed to be running okay, all gauges and readings were normal. I took it back in and the diag showed "MAP (manifold absolute pressure)". Chris had the little sensor that checks the map swapped out the next day but I asked that they drive it around a bit because it's really difficult for me to get out of work during the day to drop it off, etc. and I didn't want to do it, so they obliged and put about 30 miles on it, no return of the light and I picked it up. I've put about 200 miles on since then, no problems. If things continue to be stable, I'm going to do some back road practice runs and then hit the drag strip in the next two weeks to get some real times out of it.

On that note, here's what I had done:

1) Smaller crankshaft pulley to increase supercharger's rpm's which creates higher boost (new pulley doesn't actually go on the supercharger, pic is just of the supercharger itself for reference)



2) K&N air filters



3) Kleemann headers (pic with Kleemann vs OEM)



4) Lighter weight Kleemann down pipes (going from headers to mufflers & cats)

Heavy stock



Light Kleemann



5) High volume water pump for increased cooling (pic with small OEM unit)



6) Lower temp thermostat to keep the engine at normal temp after the upgrades.



7) Larger throttle body





8) New engine computer programming from Kleemann




Theoretically, I should now be making somewhere upwards of 600 HP; there's no four-wheel dyno in Tampa rated above 400 HP though so we'll just have to guess at HP based on what I end up with at the drag strip. It is definitely faster going by the seat of the pants measurement, it really jumps now when you mash on the throttle and the engine sound is incredible; I love the supercharger whine you get from the increased boost.



Here's a pic with my other baby reflected in the G-Wagen.



Last but not least, here's some casual video I shot of the acceleration, keep in mind the daytime video got started coming out of a corner so I was not on it hard, the second one I was driving one handed trying to hold the camera so it was not full throttle either:

.......Congratulations. Excellent write up, excellent car!! I wish we lived close to each other. Mine should be back this friday.


..........the only thing I am not clear on is the smaller s/c pulley. I understood that because the s/c clutch is integrated into the pulley, that a smaller s/c pulley for these AMGV8K cars is not possible. Do you actually have a smaller s/c pulley or a larger crank pulley? If you indeed have a smaller s/c pulley, it will be of interest to many.


Ted

 

Thanks for the detailed pics. Looks and sounds great. If that is "casual driving, night" as the video is titled, then you definitely gotta post video of aggressive driving!

 

LOL, I'll see if I can do better tonight, I have the glass mount for the camera back in the truck.

 

a lot of work has gone into this G55... impressive

 

+1 What he said

 

Oops, yeah I edited the post to be more clear on that; the pic was just of the supercharger in general. The pulley that went smaller was the crank.

I can't wait for you to get your's back on Friday, should be a monster.

 

Congrats on the new K3 G55 !! ...that car must be a BEAST! ....what kleeman parts do u not have on the car ?....get some spray man!

 

I think the only things I don't have are the camshafts and air box, I've got pulley, ECU, exhaust, throttle body, etc. I didn't do the cams because it would be pretty costly while not doing much on the low end so it would primarily only be useful at the strip, not when I'm embarrassing cars at stop lights.

 

cool..not many guys get the kleeman cam. For the air box, I would just go with VRUS's cabon fiber intake system and cf tubes....

 

you must mean larger crank pulley...

 

The sad thing is my undergrad was in engineering.

 

Sweet mods and G!~!~! Also, love the videos.
