Title: My supercharged -77 280SE
Post by: jsalova on 26 June 2011, 04:06 PM
3 years and still going strong.
We crazy Finns go to garage when boring winter starts and come out next summer with something crazy like this.
This is my 280SE -77 with a bit of surprise under the hood.

-Euro-spec engine
-Eaton M90 supercharger, 1bar / 14psi of boost (used to be 12 psi)
-Reground cams, 280 degrees
-Ported and polished head
-2.5" exhaust with 1 silencer
-Custom water-to-air IC with own water circulation
-Reinforced automatic transmission
-Modified K-Jetronic with Micro Dynamics PIC5 additional injector driver
-Electric fan
-6.9 differential
-Oil coolers for AT and engine oil
-And STOCK pistons & rods
-240 rwhp

-Sleeper looks with towbar etc.
-16" Rial mesh rims with 245/45 and 225/50 Michelin Pilot Sports
-Completely stripped and repainted few years ago

I can explain more if somebody wants to know about this car / wants to supercharge another W116.

Things to do:
Ditch that tow bar
Some minor fiddling (stereo system, nothing too "bling", polish rims etc.)
Fabricate upholstery to trunk
Minor electrical problems, ie. tachometer doesn't work.
Engine bay needs some tidying up

So what do you guys think?

awesome.

I think a youtube video should be made  8)

btw, are they volvo radiator bottles on the right and left side of the engine bay - they look familiar but not from an MB  ;)

That looks amazing! I would love to do that to my car.... one day :)

Can you give us more details on each mod and what had to be fabricated.

Thanks!!!

I've seen a 300SD on eBay before with a custom upgraded turbocharger - nothing this extensive but I'll bet it could be done.

It's too bad you're so far away.  I really want one of those for my W116. :'(

Quite impressive. Would love to hear the details about the work done. This sort of thing gets the imagination running wild with all sorts of performance modification ideas and it seems like you've covered all the bases.

What a beautiful car, I love the color.

Ah that is VERY nice.  Awesome.  I  love the colour too of the car. 

I have been thinking of something similar, but I was worried that with standard euro spec pistons and rods, the compression ratio would be too high.  I guess you guys up north are OK with no air conditioner, but that would not be viable in South Africa.

That's bloody great.

Seen the vids of this.

Definitely be good to hear more on the specs of how you built it bud.

Welcome!

OP youtube videos

Yeah, those videos are made by the original builder / ex- owner, i've been upgrading this car since then.

K-Jetronic modifications include moving the fuel distributor assy to another side and custom fuel piping.
Supercharger sucks air throught air flow meter.
With this setup, system worked perfectly and af-ratio was ok to 12 psi of boost but i wanted tiny bit more...

So, i added control pressure regulator from turbo-Volvo and Micro Dynamics PIC5 additional injector controller which controls 2 Bosch injectors (from motronic system) depending on boost pressure.

Exhaust used to be stock but it was pretty restrictive, replaced it with 2.5" custom made exhaust, much better now.

As i said, engine is internally stock 9:1 compression euro-spec except ported/polished head and 278/280deg. camshafts.
And yes, i usually rev it and drive it pretty hard  ;D.  

This car has been supercharged for 3 years and to me it proves M110 is very strong and durable engine.

Thinking about next summer already, maybe it's time for adjustable ecu, custom pistons, custom rods and 20psi of boost  ;D .

I'm pretty tired so i'll continue tomorrow, so many things to tell about this beast!

I have done the same thing many times ;) with the pants anyway.

suits sit in the cupboard for years, then when its time to wear it again mysteriously the pants are skin tight and about to explode - bending of the knees is to be avoided as well as sitting down  ::)

my usual attire is the absolute opposite of a suite, more like vagrants attire  ::)

did he borrow it off you? :D
cool car, lots of effort. amazing how much extra these engines can tolerate!
at the end of your video of the car, it has a link for a 116 with a m119 420 engine in it, now that is also some crazy effort!

so when can we expect to see your G wagon supercharged, Nathan ? 8)

Fantastic car jsalova.  A while back I was searching turbo and SC M110s and saw yours on youtube.  I wondered if the M90 was too much, thinking an M45 would've been kinder to the engine, though perhpas on the small side.   So it's great to hear that yours has stood the test of time.  I can't imagine it would be easy to drive sedately, the temptation to plant the accelerator every time you go out, even if just popping up the road to get some milk, must be overwhelming 8)

Koan mentioned your transmission and I'm curious to know if you've had issues there.  I remember reading some fella's misfortune of going through a couple of auto gearboxes in a non blown W123 by just adjusting both camshafts by 4degrees advance, creating a huge change to low end torque.  With an M90 and ground cams plus the rest of it, it makes wonder if there's potential for failure there.  but then again, three years on and still going strong..... great stuff.

Saw that M119 transplant too Nathan.  8) Uber cool.

Maybe you should stay behind the camera  ;D

Okay, a bit of upgrade here.

My friend is going to fabricate custom exhaust manifolds to my car and SC has to be removed out of the way.

So, i'll upload drawings and other specs about SC mounting blocks and belt tensioner system etc. if somebody else is interested about this kind of modification to M110.
