Hi Chris!

The car is originally a 1983 240D non-turbo with an auto trans. I changed the gearing to a 3.07 diff out of a 300 turbo, which dropped my cruise rpm about 600rpm IIRC, so its turning about 3200rpm at 75mph. I'll re do the math if you would like. I also swapped in the four speed manual trans. I manufacuture an adapter plate that allows puttin a 5 cyl turbo manifold off a 617 on to the 4 cyl 616 which makes the conversion as easy as bolting together lots of junk yard parts, so thats how the turbo got on there! I have pics in my old posts. Since then a different air filter set up is used and I've improved the oil separator. I will post some new pics this weekend after the whole Thanksgiving family drama is over!
Cheers

I forgot to mention the pickup is quite good! IP is also um......not stock.

What did you do to it? 617.95 elements?

2 Samuel 12:13: "David said to Nathan, “I have sinned against the Lord.” And Nathan said to David, “The Lord also has put away your sin; you shall not die."

How I modifiy the IP:

The pump mod is dead simple. Take off the back cover of the pump. Once inside look at where the throttle shaft goes through the pump body. There is a tube that the throttle shaft goes through that I call the start/run lockout link. This link at one end engages some other parts that limit the rack travel, the other end links to the governer. How it works is that at cranking speed the rack is allowed to move to its Maximum fuel position for starting. As soon is the engine starts and the governer weights start to come out, this link limits rack travel, and the difference is Huge. The trick is to remove this link so that you can get Full Fuel all the time! Well at least till the governer pulls back due to RPM.

Removing the link is pretty easy. There is a little wedge with an 8mm nut on it that must be removed and of course the snap ring on the far side of the throttle shaft. Slide the throttle shaft out of the body untill you can remove the start/run lockout link, then slide the shaft back in. The little wedge will drive you crazy for a bit, but once everything is back together, you are set.

Stock fuel per squirt on a 240D is about 41.5 cubic mm. Stock fuel on a 617 turbo is about 51.5 cubic mm per squirt. Just this mod with stock pump elements make about 114 cubic mm per squirt! Thats nearly 3 times the fuel with one easy little mod and you don't mess up any of the governer spring balances or anything, and its easy to go back stock if you ever want to.

With this much fuel you absolutely Must have a turbo, or maybe a supercharger. I'm thinking of trying that! Sorry I dont have pics of all this. They were lost when my old computer died, but maybe this weekend I can take some more so you guys can see what the part I'm talking about looks like.

cheers
Chris

That is pretty cool right there. I wonder why Mercedes never put a turbo on the 616.
