From BMW to Benz, hi Im Esa, but i have a q?

[Esaelias]

Ok there seems to be some confusion.

Firstly, D1S are HID bulbs and cannot just be plugged into a halogen set-up.

If you have 'yellow' bulbs they are likely 'normal' halogen bulbs and not HID/Xenon. If this is the case, the easiest is performance bulbs as mentioned earlier like Nightbreakers etc.

If you have Xenon lights from factory (which I don't think so) then for a bright white light 4300k is normally factory although I have found 5000k to be a bit whiter, may be down to how accurate the manufacturer is.

oh thanks alot, yes they are yellow ones, no xenon ones even though in the morning the bottom half of headlights are a nice white...but thats what i was asking, any performance bulb which i can replace yellow ones with a white brighter bulb that i can just exchange

i havent seen them in person yet, but i will do what you said the pictures are on here with close ups aswell

Look good to me

 

[Esaelias]

Look good to me

okey dokey thanks mate, ill just see what they look like when they arrive,

like john said i will go wheels specliast to see if they have been skimmed once

and then go mercedes to see if they genuine

 

[John Laidlaw]

That does mean completely re painted all over. You will never know how well they are done until the get very wet or get salt on them. They do look nice so plenty of good wax on them.

That's what it looks like to me Malcolm. I've tried to zoom in but the pics are not super clear, but it does not look like the sharp diamond cut is on the rim,so it looks like they've been coated. Looks a nice job though. as you say the OP won't know until the salt and moisture gets in on them.

So regarding H7 lamps.

The best going for any decent money at the moment are Osram Night Breaker Ultimate H7, these are on Amazon right now for £14.50/pair. I helped another member on these earlier this morning. At work we have benchmarked various lamps for performance vs longevity and the Night Breakers consistently come out on top.

D1S/ D2S/ D2R are all various types of HiD (Xenon) lamp and cannot be fitted into a halogen lamp unit. a) they won't fit and b) they won't work.

Brightness vs illumination: as the colour temperature goes up (3000K --> 4000K -/-> 15000K the colour changes from yellowy to white to bluey-white. The brightness as measured in lumen also increase with the colour temperature for any given power, however the illumination as perceived by your eyes goes down. Try reading a newspaper under a blue torch, you'll see what I mean (after you get rid of the migraine!) The best colour temperature for illumination as perceived by human eyes is in the neutral daylight white band, this is the 4000-5000K zone. Anything else might be bright as fook and look cool, but it's not doing as good a job and will just dazzle oncoming road users more.

thanks alot mate really appreciate it alot! the only reason i picked the ds1 ones was on the website i checked what bulbs are compatible and ds1 came up

i think what i need to do is first find out what bulbs i have in haha

i asked him now he went they come in with very little damage and he diamond cuts them once to make them 'look nice'

What exact model and year car do you have please?

 

[Esaelias]

What exact model and year car do you have please?

hi craig

i have the mercedes benz c class c200 petrol 184bhp SE Executive edition it was registered in november 2015 i think

i did want the sport but joint decision with father led us for the SE

do you need more info mate?

 

[Esaelias]

Guys how would one know if my car is a kompressor?

Nope, you have H7 lamps. If you go on Amazon there are Osram Night Breaker Ultimate for sale, £14.50 per pair from the Osram Amazon store. These are what you want.

 

[Craiglxviii]

It's not a Kompressor badged car per se, which was a whole MB brand definition thing. Yours is a turbocharged petrol engine.

ok thanks i wanted a turbocharged one, feels more powerful, i heard kompressors werent that good in long run and werent that powerful

 

[John Laidlaw]

The Kompressor is more akin to a supercharger Esa....

 

[Craiglxviii]

Kompressor (stylized as KOMPRESSOR) is a marketing name by Mercedes-Benz used in supercharged engines. The term is not widely used by other motor manufacturers.
Marques with Kompressor option W202
Mercedes-Benz W210
Mercedes-Benz W203
Mercedes-Benz W204 (2007-2010)
Mercedes-Benz R170
Mercedes-Benz R171
Mercedes-Benz C208
Mercedes-Benz C209
Mercedes-Benz W211
Mercedes-Benz W220 (S55 AMG)
Mercedes-Benz C215 (CL55 AMG)
Mercedes-Benz R230 (SL55 AMG)


So supercharged (mechanically-driven) not turbocharged (exhaust-driven). I believe that all of the recent small petrol engines I4s 1.8litre+ etc are turbocharged.

On the M113 5.4 V8, the Kompressor option went from 355hp to 493hp so added 38%. Considering it's a 355hp engine already, a 38% increase with supercharger I'd say is pretty significant.

For comparison, the Merlin I engine (March '36) was rated at 890hp takeoff power; the Merlin II (Aug '37) had +6psi boost (supercharger, 1 stage) and was rated at 1030hp so a 16% increase. The Merlin III (Jul '38) increased boost to +12psi and went upto 1310hp, so a 27% increase over the II. In each case the supercharger took something like 140hp out of the engine to operate itself. For a properly-designed supercharger I'd expect something in the 30+% mark for nett power increase. The main difference car wise between superchargers and turbochargers is lack of turbo-lag, but decreased fuel efficiency (engine drives the supercharger directly via shaft or belt; exhaust gas mass-flow velocity drives the turbocharger so effectively "free" power, but not available until it has spooled up.)

Does anyone know what positive boost pressure the MB superchargers give?

 

[Esaelias]

so criag and john the wheels came

upon inspection they do look reconiditoned but quite nice very smooth etc no marks at all apart from the back of the alloys where there are some scratches

they are a darker shade so maybe been sprayed to.... i will go wheels specialist take thier opinion then go mercedes garage to check if they are genuine

thanks for all the help guys

 

[John Laidlaw]

Well all sounds ok Esa

 

[Esaelias]

problem?

Well all sounds ok Esa

got an issue guys.


so i rang camskill tyres for the uni royals he replied, it may affect your warranty?

he goes cuz ur cars registered as 16-17 inches and it may affect sytem stabliblity and then on the motorway the lights will come on etc.... he said it needs to be registered with mercedes and they need to change the system?

im confused as iv seen the c class in the garage have 18 inches?

he also said mercedes may not accept the uni royals as they are not MO stamped?

 

[John Laidlaw]

Hmmm. Not sure on this , I'm not too up on cars which are covered by warranty.
Sounds a little anal though!

 

[Naraic]

ok thanks i wanted a turbocharged one, feels more powerful, i heard kompressors werent that good in long run and werent that powerful

They do the same thing differently.

Kompressors (superchargers) are crank driven and will deliver power more instantly than turbos which are exhaust gas driven. Turbos are cheaper than superchargers....due to fewer moving parts etc.
