What are the chances the place were i got my ECU tune from and dyno'ed are inflating the number? The place i go to is a rather respectable shop.

282 / .80 = 352hp Still low but not as extreme
dunno how you are doing your math
I too would like to know , can these be made to fit the W208 CLK55??

technically both are right,
Dyno dynamics can "adjust" but even its adjustment is not nearly as high as dynojets. Dyno jets can adjust MUCH more, dyno dynamics whether its "adjusting" or not is pretty much just actual power at the wheels.
Not to break this into a dynojet vs. dyno dynamics thread but a dynojet isn't a true dyno its a inertiameter which then backward converts to HP then extrapolates torque. Dyno Dynamics is the worlds most accurate loading dyno and yields the lowest of all dynoes period b/c it puts as close to real world load on the wheels as possible, it reads lower than mustang and dynojet as well as pretty much any other dyno.
anyway awesome work guys! I'll have to pick up an airbox from you guys in the near future!

Let me see if i can clarify some things:
1. Baseline dyno had K&Ns in the car and they only added 2RWHP. The problem on the stock C55 is air boxes are too short in height. Kompressor air boxes are taller.
2. The dyno above shows baseline RWHP in red and baseiline TQ in pink. Kompressor dyno is dark blue for HP and light blue for TQ.
3. 63 cover should work on C32. But you will need to make custom stand-offs for it to fit.
4. DynoDynamics (DD) vs Dynojet (DJ).
DD is better, no doubt, since it allows one to load and tune the car on the dyno. But here is the problem, since load can changed, so is RWHP, by simply changing load on the next run. Since load conditions are not shown on the dyno chart, we never know if load was constant.
DJ has fixed load, which is drum weight, operator can not change loading. This is why DJ is good for comparing numbers from DJ to DJ or from run to run.

Vadim,
All true, but now Dyno Dynamics has come out with "Shoot out" mode which now creates an international standard on all their dynos so you can dyno on any DD dyno in the world and it will be accurate in a comparison. The only thing is that specific shop has to have the certification (basically the shop has to pay a bit extra for the service). However they have addressed that issue, just thought i'd bring that up.
So this will fit on W208 CLK55 along with the 63 cover? The W210 E55, W208 CLK55 have oval inlets on the front of the airbox instead of circular ones on the sides, can they be converted over to use this type of an airbox? thanks

05' CLK 55
To be honest people shouldn't be wasting money on airboxes and realize that if they just changed their rear axle differential gear ratio on their benz they would drop nearly half a second or more depending on which ratio they decide to run. Benz's put such restricted rear axle ratios its ridiculous.
I would bet money the car would put down a significant amount of extra whp because that's where you lose power in the drivetrain transfer of power from the flywheel to the axle.

This is how you use your first post? $550 for 10hp from a Mercedes is one of the best deals you can get for a N/A motor. It will also be nice to know our cars dont need a governor on them because it will only do 120mph.

Who said they always read the same? Sure... some dynos can alter numbers - that's fine. They can't alter MATHEMATICS. HP is simply a formula, dependent on torque as a variable:
HP = (rpm × Torque) ÷ 5252
Consequently - no dyno in the world can show HP and torque NOT crossing at 5252... it isn't possible. High school (maybe grade school?) algebra here...
HP = (rpm × Torque) ÷ 5252

these aren't ford mustangs, you can't just swap gears, the diff ratios are programmed into the ECU, gears will cost you a couple of grand at the minimum. Please use search function noob.

I believe the "Shoot out" logo is on the graph when used (hence the necessity for licensing), not 100% sure. You would have to contact DD about that, but at least its a step in the right direction.

if u can make the 63 cover work for the w208 clk55 - will u also have the CF option (https://mbworld.org/forums/showthread.php?t=244181)? will this add another 15 or so ponies.
btw, thanks!!
its about time someone is making stuff for the N/A 5.4L

Out Of Control!!
The 63 airbox will fit a 55 with some modifications as well.
The c/f boxes will not work as they are since the inlet airbox outlet angle is different.
If VRP will make the c/f airbox specifically for the W208 CLK55 I will put my money down right now

it seems as though theres interest from all over the place for these air boxes. perhaps a group buy is in order?
im a bit on the edge because of the lose of the engine cover, but hell, im asian, if theres a discount to be had, im all over it.

For the money you're going to spend on the renntech box, I would rather get Vadim's modded airbox and spend the extra you save on other mods. If I'm correct the Renntech box goes for like almost 2k right? You're gonna spend 1k+ to get few more horses than Vadim's airbox? IMHO not worth it. For the 1k you save you can get an Evosport UD pulley....installed.
