who is the GL guru in this section?
Anyone doing performance mods? Resonator delete? Supercharger or cams?
Wife just picked up a 450 and just trying to cut to the chase.
any quick tips or easy mods to make an 08 better? 21" AMg wheels laying around? Anyone using a ML63 or other model car 63 cat back?

Maybe I can just ask where or what part number for the "rear bumper stainless cover" is? I fully know the specs of this SUV but my wife likes to pass cars at 90 mph while pulling our boat, so she wants a supercharger. If there is not one, then I will have a rotrex or procharger made for it. This is done on SUV`s and trucks all the time, so not sure why I get the book thrown at me for asking. Jeez.

If your wife gets caught passing at 90 mph with a boat in the back the judge throwing he book at her/you will be the least of your problems 
Btw, if you think the 450 is not out of its environment pulling boats at 90...
On the subject of mods- i do not think there any serious power mods out for the 450.

Serious power mod for the GL450 is called the GL550!
Want passing torque? Go with a GL 350 Bluetec. It already has a turbocharger on it and it tows like a dream.

None of them are rated different
Exotic, sorry for the interruption, but it is VERY tough around here to get good advice.
I posted a simple, DIY, and was informed I was FOS, as the service interval would be interrupted
FYI, look else where my friend, as I doubt ANYONE here has EVER thought outside the box for HP improvements.
AS for the rest, PLEASE prove me wrong
PS: FI on a 450, or 550 would be tough as the static compression is too high to make it feasible, IMHO. 4-5 PSI kit is really not worth 4-5K, IMHO.

And as far as power upgrades go, I didn't even need to think inside the box, as I just bought an AMG to satisfy that need.

Depending on the shape of the combustion chamber, camshafts profile, intake manifold characteristics and the phase of the moon a high static compression motor can be very suitable for fi and a low compression one- a complete disaster.
As far as you buying an amg- it is not a gl and there is no gl amg so whatever point you are trying to make is a moot one.

Sorry, let me spell it out. I bought a vehicle designed to go fast because I want to go fast. If the OP ('s wife) wanted to make the most thoughtful purchase, he would have purchased something like a new Grand Cherokee SRT 8, which can tow & go, as it were, not a mid-class GL (which was never designed to go fast).

And you know this how? ...Check your manual and it will tell you your compression ratio.

I had the FIRST KB Gt40 lower mustang in the country, for one.
Two, to get a substantial boost in power, aka 100% you need 1 atm of boost, approximately 14 PSI. So when you are talking about adding 4-5 pounds of boost, at a cost of 5K +, it just doesn't add up, IMHO.
Yes there are other factors, but to put it simply you can not add alot of boost to a high compression engine with todays lovely gas regardless of cam/head/chamber, etc, etc. Unless of course you now go to a meth set up. But again, you are now adding more cost and inconvenience to a DD.
AS far as the rating that I mentioned above, I was talking tow rating, NOT HP. Some guys around here are REALLY tied up to tight IMHO.

what i am trying to say is that you don't know if you can run 5 pounds or 15 on this motor as nobody has done it so field experience is non-existent.
case in point- the s2000 motor is high compression engine with ultra light rotating assembly. yet people run 14 pounds blowers without even touching the head gasket. and this is with a blower that is spun to 8k rpms (think heat). the turbo kits run even more on pump gas as less heat is generated with the high rpm motor. another example is the g35. and the ls1/2 motors. and prelude motors.. and... you get the picture.
what i mean is that one just does not know what a motor is capable of by knowing just the compression. there are so many other things at play that the only way is to pressurize one and trial and error it.

Thanks for the last statment, that is usable advice.
I hope your not one of the texters that get in my way and force me to pass you at 90 mph, before the next car comes head on.. Towing at 90 mph is a tad dangerous. Then again, we drive a 620 RWHP CL55 with 720 FT lbs of torque too. 1/4 mile race and Texas mile race and I would say a few street races too but you guys may turn me in..lol MRAMG Thanks for the heads up, I am not suprised. Always fun trolling the soccer- mom section anyway.. LMAO!

Sadly as you have found out there is not much support for the GL platform when it comes to tuning. Based on the demographic I guess it's a small market.
That said, I like your thinking! I used to think my wife's GL was pretty quick but the miles behind the wheel of the E55 spoiled that! Now when I drive the GL I feel like I have to plan my passing maneuvers instead of "gas and go".
Anyway, I'm thinking the hot ticket would be a motor swap from the ML63 as it is likely plug and play hardware wise. I suspect that you know this but the ML and GL are essentially the same from the B pillar forward. That would give you stock comfort and reliability (well, you know what I mean) with a 50% HP jump. This would not be cheap but then I have seen that you don't mind spending a few bucks on your CL!
A custom SC/Turbo setup may seem less expensive in the beginning but I suspect the costs of refining the system and tuning everything would add up before the project is done.
Of course, these are merely opinions as I have not yet been down this road.
Can't wait to see you what you do!

1 Bar of boost, 14.7 PSI, will double the effective displacement of an engine and will produce double the power with effective intercooling and boost.

May sound strange but everyone puts superchargers on thier trucks and SUV`s in Texas it seems. Well at least a lot of poeple. Very nice set up and great power. Doing all the bolt on stuff, just f `s up the SUV , for small gains.
If you search Youtube, you will see tons of truck/sUV`s with boosted motors. Very common and helps to pass safe, while towing a toy!

I have given thought to mid mount turbos. Think of the STS units mounted between the manifold and catalytic converters.

Have some friends at the PRI gathering info from the procharger style chargers. Just looking right now.

Centrifugal like vortech or procharger will add little to the bottom end tq. A twin screw or small turbos will be more suitable.
I still fail to see the point, but anyway. Have you guys driven a g55? Scary when pushed. And not in a nice way...

Yes, looking more like turbos will fit better. Looked hard at ways to custom make bracket for ROTREX and not much room. Plenty of room for turbos though.

Ok, after looking into all the Supercahrger options and fabrication, decided to go sngle turbo and keep boost around 5 PSI. Easy install , better MPG and less fabrication.
