super over turbo anyday. 
manny78 said:
installation issues mainly, ease of use, less compromized engine setup, more reliable
wait, are you talking something like grand turismo 3 setup?
is just pretty much bolting on 150hp what you want to do?

supercharger easier to install and much cheaper, go with vortech, probably the only one available for your application
if longevity is a concern i'd suggest the turbo. with a turbo your foot on the gas will end up determining boost, with a supercharger it's always gonna be high. the turbo will give the engine less stress. if lag is your concern get dual sequential turbos. that way the small turbo will kick in quick fast and in a hurry, while the big one's on it's way to max boost.

sorry brotha, boost on a supercharger and turbocharger both build with rpms,
there is no boost on either unless you bring the rpms up

not very common to supercharge one of those, kits arent as readily available for them like they are for common domestics, but I see that there is a supercharger option for that car from the factory, try calling vortech engineering and asking them if they know of anyone making a kit , a few companies make them for beamers

theere u go bor, they have a kit for a supercharger , prices are in euro, at least u know some one makes them , and vortech should have a few companys for u then..

i was told that you've got to drive a car with a turbocharger much more differently than a regular engine. i'd assume that's if you're running a high boost on it, but i don't know for certain. from what i've heard, you need to bring it up into the boost rpms all the time or you're putting additional strain on it. not sure how true that is though. i've played with turbo'ed diesels, not gas engines. we beat the shit out of those things constantly....only way to get 'em to move.

True they build boost when the RPMS are raised....however..JKERRY is on the right path, he seems to know his shit.
Turbos feed air to the motor via exhaust gas and only when the gas is pressed down, meaning the more exhaust coming out the higher the boost. When the gas is not pressed the motor creates vacuum and causes the blow off valve to relieve pressure from the motor. Meaning less strain on the motor. A supercharger always has boost on it considering it is driven by belts unless a bypass valve is installed to relieve pressure. And in most cases unless boost is higher than 9 psi a bypass valve is not installed.
But you do have to compare when choosing between the two:
yes turbos do have lag but it is free horsepower, it doesnt need the motor to spin the turbines. but since it is exhaust feeding the motor it will be much hotter than a superchargers cool air but the air can be cooled by installing a intercooler. Also, it is much easier to adjust how much boost the turbos are making, via a boost controller rather than changing the pullies on a supercharger.
Superchargers run off the motor, it takes power to create power causing instant boost. But it is much cooler air and also a intercooler can be added to furthermore cool the air charge. And is easier to install.
IMO, if money isnt an issue i would go with a turbo if the person installing it knows what he is doing. But if you are installing it yourself and have little knowledge, a supercharger is more your speed. Also make sure you have plenty of fuel to feed your machine, not thing worse than frying a motor.
Good Luck!

Have you thought about how much power your tranny and other parts can take?
Usually econo cars aren't built to take much. That's why you'll see factory turbo cars with only 200hp and maybe 250 ft-lbs of torque.

this question has been debated since the dawn of turbos and superchargers. Id go with turbo because even with all the extra plumbing, tranny work, top half work, you can customize the boost setting. with a proper engine, you can squeeze lots of power out of that thing. however, since it is a benz, i would go with super charger, jsut because the majority of after-marked benz's usually are super charged.

If money is truly no obstacle then I would buy a new car.
Otherwise super all the way.
I don't care how well it's installed, a turbo will fail more quickly than a supercharger. It's subjected to way more stress, especially thermal stress.
On superchargers the only thing that goes bad with any regularity is the belt. Also you can just remove the belt for periods of time if you want to tool aroudn naturally aspirated.

do Nitrous and be done
i'd go with the supercharger/compressor for your benz.. figure if most of the benzs are supercharged.. then there's a reason behind it... turbo takes time to spool up and also has parasitic lag...so let say you are going thru a sharp entrance/exit ramp.. you can have too much power building up as you go in the chicane before you know it.

Ditto on this.Lumberg said:
Are you willing to have your engine and drivetrain reworked for this, or are you looking for the best bolt on?
If money were no issue - dual super chargers. Look into some of the new generation superchargers. I forget the specifics of some of the design inovation (I could find out if you like), but they spool up amazingly fast, almost eliminating lag (no need for sequential superchargers). With your engine and the class of either super or turbocharger aplicable, the dual turbos give you the best potential.
Of course if money is really no issue, you could go with an exotic custom super-turbocharger.

GREAT POST SHADOW...seriously nitrous is a great alternative! I would definately do nitrous over supercharger/turbo application especially on a benz, and to Hell to people that say nitrous is cheating, same concept in all power adde situations, more air=more power

Theoreticall, that's true.
Aren't you a cop or ex-cop? I think you know that that's easy to get around. Just have the jug within reach of the driver's seat. If you get pulled over detach it. No officer this isn't hooked up, I'm just getting it back from/taking it to a friend's house.

um and how do you think the supercharged factory version of his car lasts past 30 days?
the_only_sepe

they require no transmission upgrade whatsoever , there are kits made to adapt vortechs to about every domestic car, and some foreigns , the pully for a stock application puts out low boost 6-8lb(safe) , thats all air the cars fuel system can handle. Up(10-20lb) the boost then you start compromising reliability of the motor, drivetrain etc. and require a much greater fuel flow due to the increased air.
the_only_sepe said:
that might true in most cases (and I would tend to agree since total is still not that powerful -ie below 300hp)- but I still think it is stupid to ASSUME such and not at least get the specs for the tranny and the differential etc BEFORE trying something like this...
it would not take that long and it could save a lot of money in the long run...

Nitrous is great if you want a car to run fast in a drag race or enjoy the occasional romp on the freeway. However, if your going for the jet-fighter on wheels experience, go for the turbos of supercharger.
If you really like, you can even add nitrous to that - money being no object of course.

Superchargers do not shorten a car's life span, if anything; turbos do. The tranny problems can be over come with a simple replacement of the clutch and the flywheel. As for the gear box, well, youre only going to need to replace that if youre thinking of turning your ride into some sort of 8 second quartermile beast.

A supercharger will increase the stress on an engine. I agree that if the engine and seals are solid, the life span will not necessarily be cut. There are some special issues with turbo chargers, but again, these can be delt with and a turbocharged engine can live a long happy life.Yarg! said:
I have no idea what tranny is in his particular car, but I'd bet I could have his engine built to a point well past what it could handle given frequent hard runs.

I had a Turbo Saab with absolutely no complaints about the turbo effect. If you needed a lot of boost fast....just drop a gear and punch it.
It was very hard not to speed though.

we are speaking of centrifugal in this instance, yes roots builds boost quick

I'm only familiar with setups on V-8s, I always used summit. Here's an example of one of the larger ones:

I would get a kit that is compatible with several different levels of HP increase. Start with the lowest one but if you want to go up you don't have to buy a whole new kit.
I know for the big ones you need to add lots of extra fuel in a fogger configuration. I think there is also one called a "Sneaky Pete" that is like a tiny little extra boost.

go get you a 90's model 5.0, yeah vanilla ice style 3-5k$, add a vortech blower 3k and your rollin, and they are very easy to work on and hold up well to abuse and will spank the cedes to peaces and theres tons of bolt ons available, if your like me and get satisfaction from doing things your self, you will get to tinker with the 5.0 a whole bunch I owned one for 4 years and did everyhting imaginable to it...

umm, it is much easier to add a centrifugal , and they work great too!
