The Renntech airboxes don't come around very often. It took me a good 6 months to find one. When you do come across one, jump on it--should cost you 600 to 800.

Welcome aboard.

Hey cdd,

I'm aware that they are very hard to come by, I’d be right in there as soon as one becomes on available

I'm thinking of a couple of performance modifications to take the car up to 400+bhp and I thought about a ECU remap and a Renntech box would do the trick?

thanks for the welcome btw.

Welcome aboard. The Renntech airboxes wont do much for that 800 bucks you may pay.

Thanks guys,

Wawy; I see you have few modifications on your 55, including a Renntech CB air box, is it worth spending 600-800 on one? did you see any difference? your c55 sounds great btw.

I thought it will work well with the ECU remap, well atleast that's what I have been told…

How do they make a difference??

No more than a KN!!

A tune for the C55 will do nothing or next to nothing as well. Better off to just change the plugs, maybe a res delete and true dual exhaust, put K&N in there and call it a day. Unless you want to go with a Kleemann SC, there's very little mods one can do to the C55 that'll make much of a difference for the money.

Hey michael, thanks for the welcome.

What is a 'eurocharged ecu flash'? sorry if it's a stupid question but I don't know, lol.

They (EC) plug into your OBD II port and reflash the ECU (ECM) to allegedly change some parameters for the engine, air/fuel etc etc (even can remove speed limiters). I have "personally" found that on a NA engine (particularly the C55) the tune does NOT add any HP and if it does, its minimal for the money. A tune on a C32 is a whole different story. They DO work on the C32 and the C63, however, and quite well.

How about Kleemann headers + ECU re-map and maybe if am lucky a Renntech air box surely that will make a noticeable difference…

A tune alone on a c55 will see around 20bhp, 24ibft torque and sharpens up the throttle etc..

Thanks,
Joe.

+1. IIRC, the boxes which are over a G net you like, 8-10whp?


OP, true dual exhaust is surely where it's at. if emissions isn't a problem, i'd go with LT headers, secondary cat delete, and a res delete...and the K&N filters

You can take a look at the link below my picture:
https://mbworld.org/forums/c32-amg-c...dent-dyno.html
..here you will find two other C55 owners that have tested the Renntech airbox and have shown RWHP gains. You'll notice the airbox is bigger than stock and different on the inside. My testing was done with the stock ECU. I would suspect that with a tune with a map for the airbox the results would be even better. I agree that the the "best" mod for this engine is a supercharger, however, not everyone wants to go this route (either because of cost, reliability or other reasons).

** Bad link *** Bottom link didnt work (Renntech airbox dyno)

I found this original post from AMS and WAWY:

At least it made dynoed gains so that's a good thing. How much is the airbox (if you don't mind me asking)?


Yes you could say that! If I remember correctly they are about $1250-1500 brand new for the M113 V8.

I am considering a dual exhaust, also I’m not after huge figures, if I get 400-410bhp fly I’d be happy.

I'm not so sure about K&N had them on my c32 and my previous slk55 and the on both I had maf issues, I took them out after 7K miles and fitted the stock AMG ones back in.

or maybe go with a dry filter from AFE. http://afepower.com/

With all due respect, I've never seen that on a dyno (where a C55 gets another 20 hp from a tune?? )

That's what I have been quoted from a Tuner,

he will dyno the car before and after also..

Thank you for the link buddy, very interesting, if you ever want to sell your Renntech box, please drop me a PM

Which tuner?? I'd love to see his results. Note that some dynos on consecutive runs can show as much as 10-20 HP difference with NO changes in the car. Heat soak, change in DA's etc can also affect subsequent runs. The only true dyno I believe in is the QTR Mile track.

As a side note, even Kleemann, who's done a ton of 113 engines keeps the stock airboxes on the C55 when they do a SC package with headers. That's gotta tell you something.

Newzchspy - fair point about the Kleemann SC mod, i'll soon get the car's ECU custom mapped and see how many bhp I can gain...

I have been offered Kleemann headers recently that combined with the ECU re-map should give reasonable gains... (I hope)
