DYNO: Mercedes-Benz E55 AMG Dynojet OVER 480HP

Here's the video of the dyno run - gotta love how this thing pulls!!!
Here's a link to the dyno-sheet

got racecar?

Kleemann headers - gotta love the sound, such unexpected noise on the Merc :)

Don't worry, it's all sealed up now but I had to capture the raw sound...

and now for something yummy...

Installed the new Gates Fleetrunner Supercharger Belt - Hulk Green!

Last night I finally got around to replacing (upgrading) my supercharger serpentine belt with a new Fleetrunner Gates K080505HD V-Belt  belt.  It's about 1/2" shorter than the stock belt to better match up with the smaller supercharger pulley.  Took all of 5 minutes by using the 17mm wrench, loosening the belt tensioner, and swapping the belt.  I can't believe the garage charges $120 to do this!

Here's a quick little video of my new HULK colored belt ;)

If you get this belt on Amazon - it's over 1/2 price of what most stores sell it locally for.  Unbelievable!

Trimming the fat... not what you think!

OK - not really about weight loss or removing stuff from the car to make it lighter, but ever since I had the larger heat exchanger mounted, the E55 has had a bit of a 'swollen lip' look to it... notice the bottom of the chin spoiler, you can even see a chunk taken out of it from scraping... oh the joys of bigger parts...

Well, over the past 9 months of that little 'extra' fat lip, took its toll.  Here's what I found a few weeks ago after a long drive to Monterey, CA and back.  

Yes, that's a little rubber strip that is usually below the oil cooler, and part of the underbody tray directly below the heat exchanger.  The wear and tear of little bumps here and there eventually cracked the parts off.

So, now that I have more clearance due to the plastic pieces coming out, I figured I'd give a trim to the fat lip.  Used a simple utility knife to gracefully trace the lines between that 1/4" edge and the rest of the bumper lip.  

And here's the result of my handiwork.  I think it slimmed things down quite a bit, even though it's only a 1/4" edge!

Hopefully I wont run into any more sharp pointy things!

Mercedes AMG Books - know of any good ones?

Searching the interwebs, looking for some good books about Mercedes-AMG History - know any good ones?  Did you know AMG stands for Aufrecht, Melcher, and Großaspach ?

Found this one so far...

Following on from the merger between AMG and Daimler Chrysler in 1999, things really began to happen for AMG Mercedes-Benz enthusiasts.  The special touch of the AMG engineers was being seen on every model in the entire vast Mercedes-Banz model range, from the prosaic C-Class through to the S-Class and the SLK sports cars, as well as the ML and G-Class off-roader wagons. Not to be left out was the exotic Mercedes-Benz SLR McLaren with its supercharged 5.5 litre quad-cam V8 engine that was fettled by the AMG people. Included are road and comparison tests, model releases, technical and performance data, plus advice on buying a Mercedes-Benz AMG. Models covered include the C30, 32 & 55, CLK430, 55, TDM & GTR, CL55 & 65, CLS55, E55, G55, ML55, S55 & 65, SL55 & 65, SLK32 & 55 Plus SLR McLaren.

Post some links to good ones you know!

Mercedes E55 AMG Zoomin...

not much explanation needed for this... :o)

and here's an oil filter for the E55 - good deal! :)

Data logging - man, this is fun!

With all the fun mods, and my I/C pump failing last month - I figured it's a good time to start logging ECU/Sensor data on my car.  I've always wanted to check this stuff out - but just never had the motivation and/or patience to set it all up.  I found that it's really easy now...

First and foremost you need to get an OBD-II connection that will pull the data from your vehicle.  I did lots of research and wanted to find the best 'bang for the buck' setup.  There are fantastic options like the DashDaq but they cost $550 and I'd rather put that into other stuff - so I found the Kiwi WiFi adapter for $60 on Craligslist - pretty awesome considering they cost $149 new!

This is a really simple setup, you plug one end into the vehicle's OBD-II port and there's a 6' cable that you can mount anywhere in the vehicle.  There is a little on-off switch and the wireless component lights up when it's turned on.   Basically it sets up an Ad-Hoc Wireless connection to any device with Wireless access.  In this case I'm using my iPhone4.

Obviously - the iPhone needs an app to read the data - so I went with one that is actively monitored/developed called Dash Command for $49.99 on the app store.

It's a pretty cool application and monitors your car in real time!  Check out the screen shot below!

There are 5 different tabs (along the bottom) but this screen gives me a good look at timing and the intake temps!  This screen shot was taken on 105*F day outside, so my I/C pump is working hard to keep the intake temps to ~10-12*F within ambient temps!  Much better than last month when my IATs were in the 170-180*F range!  

Lots to learn from this setup as there is SO much data now, so I'll need some time to figure out all this info to make more sense of it all - but the instant data is excellent and I can't complain to have a setup for ~ $110 in comparison to the $550 models out there!

Finally got the new intercooler installed

It took a while, but I wanted to be sure to time this correctly - I had to have one of my headlights replaced under warranty so the front bumper needed to be pulled anyways - so I saved some labor costs :)  The guys at Von Housen were fantastic!

Unboxed the new heat exchanger - looks great!

and here it is installed... (subtle - yet effective!)

now it's time to add one of these guys...

Colder Spark Plugs for the E55 - NGK LFR7AIX #2309

Looking to get some new plugs for the E55, many have said that a colder plug should be used to reduce EGTs (Exhaust Gas Temperatures) when adding more power - basically one step colder per every 75HP added. NGK LFR7AIX Iridium IX Spark Plugs have been recommended by many on the popular sites.  Granted, on the E55 - 16 plugs are needed - YIKES!

These are a great set of plugs! Really smooths out the idle and helps to keep exhaust temps under control!

You gotta be pulley'in my leg!

OK - someone needs to stop with all the group buys - just too tempting!  Ended up getting a new developmental 84mm pulley that fits on the supercharger, instead of the usual crank pulley that spins everything faster/harder on the engine.  About 28.5% of the rotational weight has been taken off the pulley which means less wear & tear on the engine and components.

Here's the new (middle) vs old (right) design - note the thickness (weight) on the OEM design, the one of the left is an even SMALLER version - but I stuck with the 83/84mm :)

What's nice about this design is that it is less weight and offers faster spooling of the S/C instead of the stock pulley - it's been developed to meet OEM quality and has a slip-resistant coating on the ribs.  Here it is, fresh out of the UPS box.  Just waiting to add 1.5-2PSI of boost :)

It looks to be a stellar part and much cheaper than the crank pulleys which (IMHO) tend to be more trouble than what they're worth on a daily driver.  I hope to get this installed soon :-)

Scoopin it up!

Well, in my last update - I was hoping to save up a few $$ to get the TTM scoops - and, well - there was this group buy going on - so I jumped in - they look great and from some testing they increase airflow by ~5% and also create more pressure (from somewhat a ram-air effect) - reducing the pressure needed by .55%

They came via USPS packaged very nicely, two scoops the mounting bolts and some heater hose to keep things from rubbing.

Here they are installed on the car, two simple holes, and a simple lock nut on each side

and here's a look with the hood closed...  

...all ready for some forced-air fun!

Add a little more air - for free!

Small changes to allow more air into the engine and out the exhaust are pretty common modifications that people make to their cars.  I went a more subtle route - by removing restrictions.  May as well optimize the stuff that's already present...

In my previous post - I put in the K&N filters - and this week I removed the rubber/plastic snorkels that come through the front of the engine bay - they're restrictive to a point - reducing noise mostly as this is an "executive" car - but they also reduce the airflow...

Previous photo of the while I was installing my new LED city lights... 

also note the 5K LED on the left, and the standard 4.3K bulb on the right...

and now with the front end 'de-snorkeled'

 now there's less "stuff" in the way of the air to get to the engine, so it was a 'free' power modification!

hopefully I can save up a few more bucks and get these nice looking TTM scoops to channel more air to the intake, they don't really provide ram air to a s/c engine, but gives more direct airflow when moving...

E55 AMG Mods & Upgrades

First and foremost, I'm not one to sit by and drive a plain old car that's not discernible from the rest - pretty much every car I've owned has been unique in it's own way...

So here's the list of modifications done - nothing too crazy - just tried and true mods.

PERFORMANCE UPGRADES:
Get some more air into the engine - for < $40/ea (and you need two) - I love these
