W126 300SD '82 Modification's
 

Hey guys sorry if i have not been here in a while, well now here i am! (by the way check out my new pictures Albums!!!) Yeah so now i got many parts to "mod" my 300SD! I am changing the intake Manifold because, i am fitting an intercooler from an Audi TT and the intake manifold is from Herr Frank, the W115 that went to the crusher.
Now i am taking out the clutch fan and fan and i am fitting 2 electric fans, with a relay and a thermo switch. The fans should activate around 80, i am going to use my Stock MB a/c fan to blow air through and, 2 Chevy/GM fans hooked up to the thermo switch "ill show you pics of my parts soon" so that should recuperate some HP and be more efficient! Why electric fans? because as most of you know when your engine is cold that when wear and use is hard on the engine with electric fans, the engine will warm quicker and that = up to longer longevity!

Since i am doing those mod's well i am going to fit my W115 300D intake and, do all the piping to the intercooler Air to Air. Well My shop is in the same building as a Tuning shop so we help each other out and i am thinking of fitting a injector in the intake manifold to shoot winter windshield fluid at WOT "even tho i don't have a throttle LOL" that should clean my combustion chambers. well that might make more torque too!

Now i need to know if i am hooking up a Nitrous oxide bottle to all this i just might when everything is done. I tried it before with the W115 and it worked great! this kit i could get it from the tuning shop next to me! but that's fare away in the future!

Now me and my machinist friend we are making a Stainless Steel 3inch exhaust for it with hardly any bends that will sound good and free all the torque! I already did the timing chain on my car and timed the injection Pump. For the record everything in an air flow going through is getting ported so there is no restriction! only the Head will remain the same!

Now the tranny will remain as Stock BUT i got a friend at a Rad shop that will make my oil pan 1-2 1/2inch deeper to allow more oil! I am adding a Tranny oil cooler next to the intercooler out front, so the tranny will be happy with lots of MB oil and lots of cooling!!!

For the turbo i am fitting an adjustable fitting in the waste gate tubing so i can allow it to boost a little bit more up to 12-13 psi max.

For the gauges i am adding a VDO Boost Gauge, a Amp meter, a volt meter, a tranny fluid temperature sensor, a differential temperature sensor, a news ambient air and outside air sensor's for the inboard VDO temp display and a EGT gauge.

So that's all for the mechanical part's unless i need or forgot something else? Anyways i am repainting the Car with MB paint and doing all kinds of custom stuff! I got a W126 420 SEL to get the electric/heated seat's for my 300SD, since they are not heated and the headrest are not electric like in the 420SEL! Well the interior is getting a HUGE HUGE make over everything is new! From the door locking knobs that are chromed to the Brand new Sport MB Steering Wheel to the MB Zebrano Shifter and so on! Everything that light's up will be blue from the gauge cluster lights to the door lights to the rear map lights will be blue. My Aluminum door sills the "Mercedes-Benz" sing lights up blue too! all the Zebrano wood is replaced with brand new one's!

So yeah i got a new camera to take all kinds of Pictures of my cars for you MB lovers out there, if you got any suggestion's comments or idea's? fire AWAY! thanks ! check out my news pics i will add many more as i keep working on my Cars! (forced induction will probably find something wrong or help me out LOL love ya Lance haha)

I love my 300SD with all my heart and i take good care of it!!!!!! "my other MB's get great treatment too but the SD is special" (by the way all the oil's are changed regularly) from the engine oil "3800K KM's" (about 2500K miles) to power steering fluid to tranny ETC i even cleaned out my Diesel tank for the hell of it! i don't care about spending money for my MB's because i love them i might seem to be obsess well i am! SO WHAT? hahahaha take care guys ! drink Beer enjoy life/MB's and beautiful girls! BYE

That is incorrect. The stock fan makes no difference in ho the engine warms up. If it takes longer that means your thermostat needs to be replaced or it has been altered with holes drilled in it.

Washer fluid is not good, it has soap and other chemicals. 50/50 (by weight) mix of distilled water and straight methanol is best.

Why? You already have a turbo.

Thats the real bottleneck in the system. The air filter, intake and exhaust are big in comparison to the head ports.

You should at least turn up the modulator pressure so it won't slip. The auto has a torque capacity of 289lb/ft, really not much above stock when seriously modifying the engine.

A VNT turbo and something other than a tiny K&N wannabe on the end of a tube... ;)

That's a Saab elbow on the 115 intake.

What is that intercooler from? Was there enough clearance to put the 115 intake on without pulling the turbo? You should look into a Fram 8038 filter, its got 2x the surface area and you should have plenty of room for it in the SD engine bay.

I'm not trying to be an @ss, but your green coolant is low...

I just threw up inside my mouth........:stunned:

why do you have a gasser front end? Meaning your fan and its supports are not stock diesel stuff

That fan blows an incredible amount of air compared to the diesel's. I used one of those years back to cool a hotrodded 390 ford.
Mine is getting the same before its put back together after the paint goes on next week.

Anybody try a belt driven fan off of a Mercedes V8 gasser? The one on the 450 looks like the turbine blades of a jet engine, and puts out a similar amount of air :eek:

Where are you getting brand new Zebrano? If you don't mind my asking?

NO MORE CLUTCH FAN! Electric fans HUMMMMMM nice
 

Well here is an update...... (nothing i am doing is either because the parts were worn off or broken! its for Performance, reliability, and do the best as i can to make my W126 Bulletproof and fast!)

EVERY SINGLE PARTS THAT GOES ON MY CAR IS EITHER MADE FROM GERMANY, MERCEDES-BENZ ORIGINAL PART'S, A BOSCH PRODUCT, OR BREMBO/ZIMMERMAN BRAKE PARTS i do not put any cheap crap in/on my cars only the Great OEM or High Performance German parts!

Hey well not i installed my new radiator AND i took off the "clutch fan" from the water pump pulley, no more cooling while the engine is already COLD, no more HP drain, no more BS! i estimated that usually a belt driven clutch fan ROBS from 6-8 HP. Since my F$CK*&G clutch fan was BAD and shaky like crazy, it probably robbed like 20HP :mad: lol

i installed new Hoses all around, new Thermostat, new electric cooling fans, new radiator, Sand blaster the water pump pulley, new water pump, New Transmission Air2Air cooling Radiator, new belts, new Mercedes-Benz dextron3 mercon3 ATM Fluid, new ATM filter/gasket, New Mercedes-Benz prestone and ah electric relay for the cooling fans.

Now i installed a GM V6 electric cooling fan, with a second smaller Bosch electric cooling fan. Instead of the clutch fan everything is now activated with a relay it can be set from 160* to 280* "that's what temperature the relay engages the cooling fans". I am going to set it at about 80 degrees "about 175*-180*" when actually the thermostat start's opening.

i will update this weekend i have to go for right now ill have more detail's this weekend! keep reading!:D Here enjoy some new pics! "might have to check my profile i cannot attach any files for some weird reason?":mad:

"Estimate" all you like, its really closer to 1-2hp.

Not with an electric fan!

Just got my breath situation squared away, and lo and behold I just threw up in my mouth again. :eek:
Must avoid this thread, must avoid this thread........:cool:

your probably not saving much hp with the electric fan. The load is just being shifted to your alternator.


Its way less bulletproof than a viscous clutch fan. You have relays, wires, motors, fuses (hopefully), connections that can come loose, and the added load cant be good for your alternator/battery/voltage reg

Er, not quite. More like the 1/4 - 1/2 hp range. And by using a mechanical power -> electricity -> electric motor -> mechanical power arrangement of the electric fan you are using up at least twice the power as one directly driving.

The reasons for electric fans are usually either due to low engine RPM at idle, an A/C retrofit on an engine not originally designed for A/C, backup cooling, or a transverse mounted engine. It isn't to save power. If you look at current RWD vehicles they still use a mechanically driven fan for the primary cooling. It is simple, has the highest efficiency, and just plain works.

Good luck with experimenting with your car. I'm not trying to discourage you but rather to point you in directions where you won't be wasting your time and money.

okay I am very new at this but a 3 inch exhaust on a turbo deisel isn't that kinda silly, all the restriction of the system is in the turbo right? So putting on a 3 inch exhaust wouldn't really free up anything (if I am wrong here and very well could be sorry in advance)
