Renntech CF airbox
Anyone here using one. They claim 15hps, but I thought I saw a thread that someone claim they were getting like 40hps, I believe it was SL65 owner. I know it expensive mod. but 20-40hps is pretty good in my book. What do you guy think about it?

Its hard to believe some of these power gains i read about.Not too long ago i read where some one said that they had somewhere in the vicinity of 20-25 hp fo just filters.
What i think would be a great combination ,is the air-box mod along with the kleenmann t/b.Oh...and the mega hp filters.

40 extra ponies with a redesigned air box?
Just Mercedes/AMG really suck that bad? I would think it wouldn't cost a lot for them to engineer an efficient air box.

First line is completely stock, 2nd line is with the ECU/TCU upgrade. and the last line is with the CF airbox. This was from when it was first installed, It showed about a 25hp gain on 100 octane fuel. It had a larger increase with 109 octane , and you can take the air filters out when racing to give it even more power. But also keep in mind this is a different car, Im not even sure what the E55 would produce

Yeah but again, you are talking about a cargo ship sized motor compared to our V8's. The Twin Turbies seem to benefit much more from every little thing done to them.
ECU on the friggin things adds 127HP with 222 fl lbs more torque.
It's apples and oranges.....the V8 and the V12 from hell.

why dont you go look at my origional post... i stated that we had a 65 and that i was unsure about the E55's. I know the engine types are different and turbo vs superchargers will be different, and all i was trying to do was to give some input on how well the CF airboxes from Renntech were actually good upgrades.

Look at the post regarding pictures of the Renntech box in the SL55/SL65 forum and you will see a picture of the box installed on my SL55.
