4 years of ownership...

Amazing it's been 4 years that we've owned our E55 AMG!  Love this car...

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

New dyno tune and new power numbers!

We had our local tune and dyno meet - Jerry from Eurocharged came to the Bay Area for a few days to tune about a dozen cars.  Always knowledgeable and very professional - excellent customer service!

My car put down some great power numbers - my goal was at least 469HP (at the wheels).  Why?  Because the factory rates these cars at 469HP at the crank - which means they make 390-420 factory.

It was mid-afternoon and ~87F but the car made 481rwhp and 519rwtq

This was with the 83mm S/C pulley, and Kleemann mid-length headers - plus the tune.  About 80 more rwhp from stock - VERY noticeable!!

Overall - really happy with the results!  Of course, everyone says I need to go for 500rwhp now (LOL)

Gotta love Dyno time!

After my previous dyno results, I had to get my inter-cooler pump replaced.  It's amazing how much power is lost when you have lots of heat.  My IAT (intake air temps) were in the 170-180* range which is way too hot.  Since that dyno last summer, the pump was replaced and I have a heat exchanger that is 2x the OEM stock size.  Now my IATs hover ~10-15* above ambient temps - woohoo!

I took my car to Universal Technical Institute (UTI)  in Sacramento.  Nice thing is that my nephew is a recently graduated student (and driver in the video below) and we ran the numbers on the Dynojet - MUCH better!  The instructor was a big E55 fan and it was great to see about 100 students crowded around the dyno room - man it made some noise!

The printer was almost out of ink so sorry about the hard to read graph.. 446HP and 487ft-lbs!

Gotta love that crazy torque!

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

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

Dyno and a disappointment!

Well, a few weeks back we had a group Dyno day - never did that before, so I figured why not check it out!?  My brother and I drove a few hours to San Francisco and the guys at Dito's Motors were great!  Two days of dyno tuning for our group - probably 15 guys with their AMG power.

Jerry came in from Texas ( http://www.eurocharged.com/) to do the dyno tuning - and MANY guys had a blast and some big power was put down.  It was a usual Bay Area day - about 58 degrees outside, of course my brother and I forgot that it was colder there so it was quite chilly in our shorts and T-shirts (LOL).

I had my first run around 11:15am - got on the dyno and did a baseline...  

A whole whopping 400HP at the wheels... which isn't all that bad, but in perspective to other cars but we knew something was up...  my secondary water pump was failing so it couldn't cool the intake charge, my IATs were 170-180F so the computer was dumping all the fuel possible into the cylinders which pretty much made my AFR's dive into the low 10's (most likely into the 9s and even 8s)...  so we had to pack up and get a new pump installed...  The guys were great at the shop, a few guys even offered to replace the pump that day and get things dialed back in- but I let it up to the warranty to fix things (hey, that's why you buy one!) :-)

Oh well, next time I run into a Dyno - things should be much better!  I got a new toy to start logging my ECU to make sure stuff like this doesn't happen in the future... next blog!

Got some new stuff installed!

FINALLY got the S/C pulley installed, and re-tuned from Eurocharged - wahoo!  Also, during the downtime had the plugs installed (NGK LFR7AIX) and the brake fluid flushed.

  

I'll have a dyno tune done later this month to see what power gains are to be had with this lightweight pulley but the torque curve is MUCH broader than before - almost feels like an even BIGGER V8 or maybe a V12 :-)

 Next on the list is a new Gates K080505HD V-Belt, this will help keep this pulley from slipping as the stock belt is a little long at 51", the new belt is 49.6" and should keep things snug and spinning!

So far so good, the new Heat Exchanger from Fabtech-Performance has kept the 100+ degree days at bay and kept the S/C from overheating.  Next is to start logging data, really curious what the IATs are now with the new pulley and blistering CA heat!

To sticker, or not to sticker, that is the question...

OK - a little promo for the Eurocharged team  - Great company to work with so far, and very good stuff!  They sent these to me in the mail...  they're grey to somewhat match the silver.  I know, I know - if I got yellow or red stickers it would add 50HP- but I'm ok for now ;)

It will look a little like this... but my windows have a little tint so would darken the background

So what do you think?  Should I put them in the rear quarter windows ?
