mustang cobra bites the dust
A bright pre-99 mustang cobra was stomping around on the freeway with a really loud, but nice sounding exhaust. I pull up next to him and give a little gas so he could hear my exhaust as well. He bites and we line up to go. He stomps it and I hear that 4.6 roar...until I stomp on my 5.4
Walked away from him like he wasn't trying.
Maybe all he did was put some cherry bombs on the back. I thought the non-supercharged cobras would put up a little more fight than that!
On the other hand...the supercharged cobras are no joke!

Obviously you didnt see the youtube video a fully bolton 04 Cobra ran a stock c63 from a roll. They were close. Just boltons on the c63 your in the 11s trapping 120+.

Bolt-ons minus a pulley I'm sure. If 450-470rhwp and low 120s trap speeds are slow, well....

Nice kill, N/A 4.6s are kinda a joke, not gonna lie, seen plenty to know that. I think you all are missing the point that this story is vs. a non blower Cobra not an 03-04 S/C. Just sayin.

Right, except on your mailmans salary you went and got your gf to cosign on a c63 for you. Too bad you purchased an overpriced n/a piece of garbage....or are you leasing? Those cobras will tear you a new one..Wow, you're still jocking a 327hp dyno chart? My old *** dsm (the same car another member here has that you won't race because you're a COWARD), made more than that w/less than $600 in it.

Go drive your POS DSM and run it into a wall.

What was the temperature on the run, also what gear? Also I think the gearing may have been off a bit b/c the redlines don't match up which may explain the slightly higher numbers, it shows going to 6350-6400rpm, usually on DDs the redlines should match up perfectly. Something tells me your car may have software also based on the shape of the curves. Stock curves on CLK55 AMG should be completely flat past 5000rpm (the CLK55s are software detuned from the factory at 342/376, otherwise they would make same numbers as the E55s 349/391).
Most W208CLK55s will dyno between 260-290 at the wheels on DD dyno. In addition, DD dynos for mercedes front engine RWD autos have a drivetrain loss of 22%. So that means @ 327wheel HP you would be making 420HP (which is obviously not possible). I don't mean to be a buzzkill but something is not right with the dyno. Whether the operator didn't calibrate the gearing properly or over compensated for something else (not sure). Assuming you have software, you should dyno somewhere in the 290-310 range (at most). Either way, it appears the car is not stock just based on the shape of the curves alone. If I were you I would go back to the shop and ask the car to be redynoed for free as they results are inconclusive...
There is a possibility you do have engine & TCU software done which will explain how you have a 6400rpm redline (like the later model AMGs), and if so I wonder if they somehow programed Torque converter lockup to kick in at higher rpms but again not 100% sure what setup your car has. If that is the case then yes those numbers could be possible on a DD dyno, otherwise it just looks like dyno error.
I have attached a picture of what a true stock W208 CLK55 should dyno on a DD dyno (customers dyno). That is on a bone stock CLK55 with 49k miles. Also you can see the redline rpms match up and the shape of the curves are true stock shape.

The MAF screen delete does not make 15 HP, K&N filters only make a couple of HP and the stock air filters are a much bigger restriction, gains from MAF screen are purely psychological. Something is definitely not right with the dyno, you should go back and have it redynoed. If your redline is 6000rpm on the road, and the dyno shows 6400, then obviously the right specifications were not entered by the dyno operator (they should do it for free). Think about it, the numbers do not add up. If you were making 420HP in a car that weighs 3450lbs your times would be a heck of a lot better than low 13s (or even high 12s).
If you look at both DD dynos provided (both the one I posted and the one in the other link), both dynoed 263HP (within 1 HP of each other), so obviously that's where you should be at roughly. 263.x comes out to 337-339 (a few HP shy of the 342 rating which is about right considering the cars have some mileage on them & etc). Unless the dyno operator tried to manipulate the numbers in order to give you crank numbers or give you a dynojet equivalent (which some DD shops shouldn't do but some do b/c of peer pressure from those saying "why is it so low" blah blah), then I could see how you could get 327HP, but 327HP on a properly setup DD is A LOT of power.
Not trying to be blunt or impolite at all, I am merely trying to help you out so you do not have false expectations of what you are really making. If you really want to double check the numbers you can see what you dyno on a dynojet. If the numbers are same or higher than the dynojet than something is definitely wrong, normally they should be separated by about 4-5% to the downside, and I just don't see you putting down 343HP @ the wheels on a dynojet on a bone stock car when crank rating is 342HP. Just trying to be honest & help you out.
with that said... the W208 CLK55s are deceptively quick and with the right NA mods they can beat new M3s & some of the heavier compressor AMGs (in some cases with ease).
Hope that helps.

The Standards of Ethical Conduct for Employees of the Executive Branch (Standards of Ethical Conduct) prohibit an employee from soliciting a gift for himself or another. The Standards also prohibit a federal employee from accepting a gift from a prohibited source or one given because of the employee’s official position -- unless the item is excluded from the definition of a gift or falls within one of the exceptions set forth in the regulations. As a general rule of thumb, any item with a market value of more than $20 is considered a prohibited gift. Cash and cash equivalents in any amount are always considered prohibited gifts. 5 C.F.R. Part 2635.204
In addition to the prohibition from soliciting or collecting cash, the CSAP will not permit a PCC to redirect PCC funds to finance any charitable cause, scholarship, relief or assistance fund, insurance program, hardship loan, political activities, gifts or other causes or activities not directly related to the PCC Mission. (Publication 286, Charitable Endeavors, page 15.)
