Awesome job Brandon...and yes that was totally different that I believed the right one was.
You earned a place on the Mercedesshop Hall of fame for that one.

Excellent Brandon!
How about a brief comment on the before and after... Looks like you gave up smoking for amateur radio. Where's the ant for that Icom? I didn't see it. 73s, Dan N5MRG

Awesome job!! You may want to try lower boost pressure to see if EGT's come down a little. I just did this on my 603 and the initial results indicate 50-100F lower peak EGT's, when dropping from 15psi down to 12psi. There's no apparent loss in power. I'll be verifying all this at the dragstrip Friday.
When you turn up the full load, this will also increase the fuel delivery off-idle. That means you may need to turn the ALDA "down", as in leaner, to compensate. Casey had to do this on his 603 to reduce smoking off-idle, but that was on a maxed-out pump. For a slight increase in full load, you may not need to fiddle with the ALDA. I'll be trying a half-turn on my 603 soon... within a month, I hope. I'll be watching EGT's closely and will return to the dragstrip to verify power gains.

Perhaps I should get more serious about an IC now since we have the "final" word on the full load stop.

I still haven't figured out a way to put an intercooler on my W116 without major reengineering of the cooling system.

I haven't looked close at a 116, do you have any space in front of the AC condensor between there and the front bumper?

Hi Brandon,
You may well be right about the top screw having some effect on fuel delivery, but I've had a local bosch tech identify a different adjustment for full load fuel quantity. I'm sure you will keep us posted. why don't you see if you can turn it up enough to really lay down some black smoke and then back it off til your happy with your EGT. I've made the adjustment the local tech identified and it definitely increased the fuel. I had to crank back down my ALDA to limit off idle smoke. In the two days I had to test the car I shaved four seconds off 0 to 60, before my son flipped the car and wrapped it around a tree. By the way the picture on your web page with the pump sitting on a bench is from my earlier experiments. I wish I still had an expendable car to play with. I think it is great you're documenting your efforts so well.

OK now that Bob has come forward the adjustment I made he is speaking of is the large one to the right of the idle fuel adjustment....my car has half the miles on it his did which could explain why mine is overfueling at half the optimum adjsutment for his.
This is the one that is causing me problems with idle speed and its reluctance to return to idle.....the one that at three turns out had it idling at 3,400 rpm and at 1.5 turns out had it idling at 900 but slow to return to that speed. And this being still too far out to suit me even though the EGT is still just in spec...there is no doubt this adjsutment does increase the fuel delivery also, Brian Carlton has followed my car during a full throttle pullaway from an intersection. Becasue we have been told by some that adjsutments on this pump are inter related with others I am wondering if one does so with a low end bias and the other with a high end bias. It still would be nice to get the word of an Bosche tech to verify this. I will be pulling my IP again to zero out this adjustment back to original spec...and try Brandons...to see if I have less driveability issues with that adjustment. But that may be a couple days before I can do it.
