HEADWORKS...
thats the thng hehehhe. i kinda sensitve on the maintanance thingy... i already have headers, high flow pipes and x pipe ,filters and software upgrade.. im thinking of i myt get some few more HP and TQ with the headwork..... thanks
I remember when you started asking about the mods, you just wanted all bolt on stuff. Now you're getting into head works and later maybe something else. Nothing wrong with that, if it makes you happy. By the time you get all these little mods that you want done you would have spent a considerable amount by the time you add them all up. And as AMS has stated, you may not get the increase in power you are expecting. Remember, that numbers and the actual good old Butt Dyno can be two different things and feel. So, why not look into getting a super charger instead. I'm already drooling over ABALONE's.

I would recommend staying NA for your application, you still have more power to extract out of the car like crank pulley, accessory pulleys & a few other options as well so you aren't completely at a dead end but you have done many of them already.

Strictly sticking NA, what would the other options be other than having to open up the engine and changing internal parts?
does the phenolic spacers really work? where canwe get one? is there a company that makes big thotrle bodys for our engine? lighter battery what type can we use? intake box is renntech worth it? thanks
Running both crank pulley & accessory pulleys will free up every last HP out of your serpentine system and give you amazing low to mid rage as well as high end HP. Normally, other then that you can do custom software tuned for high octane, but as you said earlier, you are worried about octane in your country so I wouldn't recommend it for you. If you are doing heads, I would definitely up the exhaust ports by roughly 2mm and smoothen out the exhaust ports. Between the two crank pulley makes more up to 5000rpm, but accessory pulleys make more after 5000rpm (but do very little below that).
On the intake side its better to leave the surface rougher, but there may be a few key areas in which you can remove material to improve flow, but honestly AMG heads are pretty well flowing as is, most of the power to be made is probably on the exhaust side of the head since the stock exhaust ports are slightly smaller than 1.5" (roughly 37-38mm). Increasing that to 40mm would improve potential airflow by 10.8% while still being small enough to fit most headers. You don't want to go any bigger than 40mm really.

There may be another brand, I'm not positive. They will give you a little boost on very hot days or with hot/hard running.
You can find more about lightweight batteries if you search here (try Braille, Optima, etc.).
Hooleyboy on this forum did a comparison: stock N/A airbox, stock kompressor airbox, and Renntech airbox. Basically, the stock and kompressor boxes are about the same. The Renntech airbox gives some small gain (I think about 8 hp).

The Dunlop looks like basically the best all around performance tire made.
The stock AMG airboxes are great, all you need is K&N filters and you are pretty much set. Until our Big bore throttle body comes out for the M113s V8s there is really nothing else that can be done on the intake side of the motor. After all, it is a cold/ram air setup from the factory so really air filters are all you need.
phenolic spacers won't really do anything on an NA car, they are meant more for kompressors car that have very high temps due to boost & SC heat. On an NA car they won't do anything really.
Now, in theory, you could have the entire outside of the stock intake manifold coated with a true heat resistant ceramic coated to make sure as much of the heat stays outside the intake as much as possible, this will do much more than heat wrapping intake tubes or the airbox (which is pointless b/c the massive stock intake manifold is made of metal, where as the airbox & intake pipes are made of heat insulating plastic).
Lightweight batteries are good, but these AMGs have alot of drain when the cars are off, you have the drive the car at least once every 3 days. You definitely cannot go 12 days without starting the car (speaking from experience).
Hope that helps

thanks on the site of the phenolic spacers i have experience uisng those king of spacers on my previuos cars and it works well cause i live in a hot country. il look into getting one set for my 55. on the side of the renntech airbox hmmm 8hp for 1899USD wow ill think of it also alot of money for small gain.....but im aos considering it cause i want to maximize the NA power of the 55

thanks AMS. thats true about drain in the car. im xcited about sour throtlle bodies. when is it coming out? thanks and alos doesnt the Knn filter cause thr MAF to go crazy?
Most likely late '09/ Early '10, lots of R&D required so it will take time. No, K&N filter is totally fine.
