Glad you got your money back from the dyno run! I still need to figure out an rpm source as well. I disconnect my kickdown switch and have the guy run it in 3rd. He goes up through the gears, then lets it back down to 1500ish rpm in 3rd and then goes for it. It took him a few tries to get it right, but it seems to work ok. He reads 3k on the tach in 3rd and holds it there to 'calibrate' it to the rpm vs wheel speed. The torque converter ratio throws it off, but it's better than nothing at this point.
On a side note, I've been playing with a spare MW pump I have (1981 300D na). I've been checking how the ALDA system works, and it seems that if the alda rod is down too far and you floor it, it wont give full fueling. (I've been checking with the top cover off, so the spring is not pulling it up.) There is a catch or notch that the alda rod has to pull up far enough to engauge and give that last few mm of rack travel. My concern with this is, if the alda is adjusted down just a hair too far, when its floored the alda can't pull the rod up in time (no/low boost) to allow for full fueling. Rudolph, I don't know if your M pump will have this issue due to your external custom alda goodness, but for the rest of us, this could be causing low dyno readings. I was disappointed in my 5hp dyno increase from ported head, cam, bigger turbo, etc but I've been thinking that the alda wasn't allowing full fueling. It certainly felt better on the street than 5hp, but I had boost before flooring it. I'm working on a test set up for mechanical adjustment of the alda. I'll let you all know what I find. Also, if someone has more, or more complete, information on this, please feel free to share. Oh, Rudolph, feel free to move this rambling side note to another area if I'm hijacking your thread!
