Now that my AC is fixed and out of the shop (and my wallet much much lighter), I wanted to see what adjusting the ALDA would do for performance. I don't believe in "seat of the pants" testing. I've dyno'd my Nissan about 30 times testing parts, and I've dyno'd and 1/4 miled the CLK just to keep those guys at AMG honest

So I did cheat a little on this "tuning" session. I used a G-Tech to simulate 1/4 mile runs. Not the most accurate measuring device, but not that un-accurate for something that looks like it came out of the radio shack clearance bin.

So, I cleaned the banjo fitting and the line going from the intake side to the gizmo on the firewall near the brake resevoir (I'm drawing a blank...) and then the line and fitting that runs down to the ALDA.

Someone had evidently tweaked it before, since the locking nut was exposed.

So my first two 1/4 mile runs with the G-Tech (OK - no laughing!!)

71.6 mph 20.28 sec
73 mph 20.15 sec

turned the ALDA out 1/8-1/4 turn

73.3 mph 20.01
second run screwed up on the measurement

turned ALDA out an additional 1/8-1/4 turn

73.2 mph 19.93 sec
71.9 mph 20.28 sec

tried to loosen the ALDA more and discovered it was backed all the way out! So, I turned in clockwise a good two turns just to see what happened

72.5 mph 20.55 sec
73.4 mph 20.48 sec

So... my ALDA is basically not impacting performance at all. The car is a dog until about 2K rpm... the lines are clear, though I did not blow out the thingy on the firewall. No ridiculous amount of smoke in my opinion, though I think it is still slow to boost. 0-60 times I think were in the 14-14.5 range if that tells you anything.

Ummmm - comments? The A/C was off if you were wondering.
