I have this setup and the $70 K&N filter it took to get it to flow right. I hate the K&N its a pita to have to clean it. The price of not having to deal with the f*#&)(@g stock air filter again. Priceless. It also takes a few bends (although this type of install didn't) out of the stock flow.

I wouldn't recommend it, I wouldn't do it unless I had to. I was just tired of replacing mounts and brackets over and over again only to have the damn thing rattling again.

I'm sorry but you have some math fail going on there.

...... or just keep the stock 617 setup as you won't see any gains.

If you must try the 603 setup on the 617, you get to figure out how to move the breather and drain tubes around too. Fun times!

People!!

I see the main complaint about the stock system is having to replace the rubber mounts and the bracket on a regular basis. If you want to stop that, just follow this advice from the late Randy Durrance.

Quote:
"The air filter mount problem has existed long enough. This is the
repair.....
Looking at the air cleaner, notice the small space between the air cleaner
and the valve cover. There is a flat area on the air cleaner housing near the
valve cover. The repair requires an old rubber shock absorber mount, a 6 mm
bolt (10 mm hex) about 10 to 12 mm long, flat washers and a nut. Make a mark
on the forward area of the flat side of the air cleaner housing (toward the
valve cover). Remove the air cleaner housing and drill a 6 mm hole at the spot
you marked. Put the bolt in the hole from the inside using the washers and
nut. Now you have a bolt sticking out of the air cleaner housing... Take an
old rubber doughnut from a shock absorber and stick it over the protruding
bolt/nut. Be sure the bolt does not stick out of the rubber.
Reinstall the housing and viola the air cleaner housing is unable to generate
enough momentum to break the bracket. I've been doing this for about 8
years....never had a second air cleaner bracket break.
The idea is to limit the movement of the housing. Even when they were new the
brackets were prone to failure.
Regards,
Randy D."

Don't bring common sense into this!

Also, I use those injector heatshields too.

Do those heatshields really make a difference? When I tried to buy some, one of the older parts guys at Star Motors told me a few years ago that I didn't really need them.

For the few dollars they cost, I threw them on.

I think those are more of "grease" shields than heat shields.

Tough crowd!

I just would ask why not use a stock setup to begin with. The little rubber things that the af sit on are pretty cheap and easy to change. I keep some around and so don't get frustrated when one goes bad.

...Ooops, sorry. It was 322 km/h. That would be 200 mph. The V8 they put in it later came closer to 300mph.

Still, pretty damn fast.


My point was that, "stock doesn't always mean best".

Well in the case of a stock '84 617-Turbo that makes around 123hp/170tq... I don't see it going anywhere near 200mph unless it had a GE built J79 strapped to it.

Point blank, stock intake isn't restrictive, nor is the stock exhaust system.



If you want to spend some time, figure out a way to mount a better A/C compressor to these motors.

Well, I'll let you argue with the folks in Stuttgart about that.

Why? Go spend $40 and dyno your car stock, with no exhaust, with no air intake, etc And prove yourself to us.

Issue is we know you're wrong if you think going to a different air intake assy on a 120hp car is going to make any difference.

The W126 has so much drag I'd be surprised if it could hit 175mph, let alone 200mph in stock form. You'd be out $30-50k I bet to make the suspension correct to take that much wind speed.

That is one of the weakest retorts we've had on this forum in a long time!!!!!

To original poster:
I've said so many times: If 125HP is the problem, 126HP ain't the answer......

And I bet you didn't achieve that. But what you did achieve is allowing somebody to open your hood and see a BUICK air intake cobbled on top of your classic German diesel engine.

You should be required to sell your MB and buy a Fairmont.......

Guys. Take a few deep breaths...

You're going to have to find someone else to argue with.


Go to your favorite search engine and type in C111. Do some reading. Or better yet, get on an airplane and go to Stuttgart. It's there for all to see.

It's a big world out there.
