I want to adjust up the inj pump on my '77 240D automatic. Yes I know they are gutless wonders but I want to tweek up the fuel to get it off the line better. I adjusted the altitude compensator out all the way and still, I see no smoke. When it gets hot outside(we have been in the low 100's)It becomes MORE guttless on take off.
Is there something under the alt compensator that can be adjusted up?
I had a VW Dasher Diesel wagon with the VE Bosch pump and it could be adjusted up to pick up more power. Of course too much adj up and it smoked.
Anyone ever tried a set of TURBO injectors in a Non Turbo engine?

I have been wanting to do something similar. I have even considered trying to find an old IP manual and getting a used IP and trying to "adjust" it myself.

The used IP idea would be more suited for a project car I suppose but I have had similar ideas. For instance I have seen on the newer diesel engines in pickups (A big difference from my inline 5 I know) they can be adjusted (with a computer) to dump all kinds of fuel into the engine. I beleive this created a much quicker acceleration, but also a nice sized black cloud. I have never ever seen black smoke come out of my car. I have had blueish smoke and a little bit of gray but never any black.

Anyone else share our sentiment?

You know somebody has to say it................................



















If a 240D is too slow for you..........it's time to move up in the program.

I do have an '83 300turbo for a donor to my 240. I just want to pep it up a little to make it more drivable......especially when the A/C is on.

I believe it has about 67hp.

If you were to "pep it up" by 10%, it would have 74hp.

See where we're going here...............

The clear logic of this post still made me giggle.

BTW Brian, I was mowing today and my 10hp Briggs seemed kinda soft coming up the hill with the blades engaged. Do you think I could..................................

..........add a turbo..........Jimmy??

I sure would like a diesel Kubota lawn mower, btw. Too bad it would cost more than any MB I've ever had........

Hijack over, back to pump adjusting banter......................

I guess that I don't get what you guys are trying to say. All I am asking is if there is another fuel enhancment than the alt compensator to add more fuel. TODAY I am driving a 240 powered 240. Some day I will get the 300Turbo in it. When I want to go REAL FAST....... I jump in the DODGE!

You are pretty much stuck with a 75hp wall without adding a turbo to get more air through the engine.

Hey... I'd take 75 hp. With the compensator backed off all the way, I still don't get smoke.

You will find the adjustment with your right foot.

Check to see that the linkage is adjusted. The only other adjustment is to adjust your expectations.

Have you reset the injection pump timing or checked it? Checked for excess chain stretch? Adjusted valves? Because the 240 has so little you really should make sure it is tuned to the optimal point first. Perhaps you have already? Trying to turn up the pump to compensate is just covering up perhaps to some extent. What kind of fuel milage are you getting? I know from buying them that a lot of them have not had a basic check since forever it seems. Some even had linkage wear problems that created a situation where with the pedal to the floor the pump lever was not advanced to it's full throw and they were driven that way for years. A couple I did in the vendors yards just to get them properly drivable for the long trip home. Left the vendors speechless at the improvements as they had figured it was just the 240ds natural non existant power for years. After all everyone had said they had no power so theirs was normal as well of course. They had just lived with it. There are the two clues things are bad. Lack of normal average terminal velocity. And fuel milage to some extent. It just cannot do either properly unless tuned for it.

I was reading about tractor pulling and their diesel setups this weekend in a book I have called turbochargers (I highly recommend it but don't have the author right now). They say that tractor engines that normally have 175 hp can run up to 800hp with no internal mods to the engine. They said the key is a two staged turbo system (one turbo firing into another turbo, 2 intercoolers, and LOTS of fuel. They claim that with this much cooling of the incoming air the engine actually runs cooler than when it was n/a and the exhaust gas is also much cooler.

I will try to scan the chapter and maybe post it it was very interesting and it gave me dreams of a hot rod ponton chassis with a motor from an sd..... Well one can dream can't they.

..... Oh well back to the point. The book said that just a turbo will do nothing without more fuel (on a diesel that is). They also said that many manufacturers limit the amount of fuel that their injection pumps can provide to avoid excessive smoke. I also found this interesting.

Have you ever been to a tractor pull? I've seen them with GLOWING WHITE exhaust manifolds after only 10 seconds of pulling!

Watch this!
