Dustin's '06 C55 progress thread
Hey Guys, up until now, I've been posting updates via individual posts. From now on I'll be posting updates to this thread only in hopes of making it easier for anyone who may wish to glean something from my experiences.
I just scheduled my custom Eurocharged dyno re-tune today for the PTE cams and Needswings DCAI. Next Tuesday morning @ 10AM I'll be sure to update Tuesday evening. I've missed 2 opportunities to hit the drag strip so far this year as a result of a "minor" fender-bender (ESP is now my friend!) and subsequently realizing, at 8AM, on a day with -800-ish DA and a 10mph tailwind, that the body shop lost the key to my security lugbolts I'll detail the rest of my hostility toward the body shop at a later time...
I was hoping to get a 1/4 mile time before a retune but it didn't happen. Hopefully I'll get the security bolts out by next weekend.
In the next few days I'll post some pics and info regarding where I started to where I stand today. Stay tuned...

Cant wait to see your future posts. Ive been taking the same steps as you have in terms of modding so far, just trying to keep up with the best
Does needswings make a DCAI for the C55? or did you just get the E55 one?

He used the one for an SLK55. I want it for my car since the E55 elbow rubs on the wiper cowl and makes an irritating rattle, but I'm tired of spending money on my car.

Needswings has it for the C55 on their website now. Like RS said, I just used one for the SLK55 and swapped the tubes for the kevlar CLK tubes for a slightly better fit. I still need to post vids of the intake and exhaust post-intake and cams...I'll try this weekend.

Here's a vid of both intake sound and exhaust...

...... Sounds amazing Awesome job Dre, setting the bar up high for the rest of us C55 guys! Definitely a car/owner I look forward to hearing about.
How does the car feel now with cams?

Well, nothing comes easy I guess...I drove all the way from Baltimore to Moore Automotive in Fairfax VA this morning for the dyno and it turns out they broke it last night. I got no phone call as they neglected to write down my name when I made the appointment. They're trying to get the part overnighted, so I might be able to coordinate something with Eurocharged by Friday(?) I'll let you all know what works out. I really need to find a dyno that's closer to home and get a new baseline after the retune!
Regardless of what happens with the tune, the weather looks perfect for Cecil Dragway's test & tune Saturday. with any luck, I'll be there with a new tune, but I should be there either way.
Thanks for the kind words guys, they are much appreciated! After this gets straightened out, it's time for some new wheels and summer rubber, then Wavetrac and EC TCU tune.
Niko, It does feel like it pulls harder up top. How much of that is gain and how much is due to changes in powerband I won't know until I get some dyno or dragstrip data. Fingers crossed that we'll know by Saturday

Tires are Hoosier DOT radials in 225/50-16's on Sparco Assetto Gara's. The 225's have a tread width of 8.8" and my street 265's are 9.5". I figured the 3/4" I was giving up would be negligeable with the extra grip of the DR's and there was the added benefit of a decent weight loss and about a 1/2" smaller diameter. You can see in the pics how they compare.
Weight-wise, about 1/4 tank of pump 93, trunk empty except for a fire extinguisher and floor mats out. Sadly no weigh station at the test & tune at Cecil, but I will get it done before I start focusing on weight loss.

If you are interested, I can take any measurements you think might help next time I'm at the track. The Sparco's I'm running are only 17 lbs compared to my 30 lb 19's. The Hoosiers are 18 lbs and my all seasons are 23 lbs. Not a bad reduction of rotating mass

nice man. you still running stock intake? That would help free up some breathing room for your girl especially on the track. Might help those revs. get maxed out faster

All those plus the Needswings intake and DR's on light 16's. My best on street tires was 12.796 @ 109.89 with a 60' of 1.977. Switching to DR's, the crank pulley and the Needswings intake dropped me to 12.345 @ 113.50 with a 1.855 60'. Since my 60' dropped so little, I'd attribute the majority of the gain to the power mods and lighter wheels/tires. No retune for anything since the headers.
The only thing that changed between then and the 12.105 was the cams and slightly better weather. No retune. I've only read of one member who swapped his SLK to PTE cams and he reported somewhere in the neighborhood of a 10 whp gain on the dyno without a retune. I guess the cams and the intake really like each other What's strange is the feel of the powerband now. I don't think I've given up anything down low, but the upper end pull is definitely more pronounced. I'm dying to see what the dyno curve looks like!
