Was time to do a little something to the 231!! Had read good things so thought it would be a great time while engine is pretty low time (less than 290 Hours) to install a Merlyn Black Magic Upper Deck Pressure controller to compliment my airflow systems intercooler on my LB engine. I never thought it was much of an issue/ extra work load messing with throttle settings but I did want to reduce the load on the turbo at lower altitudes and increase my critical alt since we do fly pretty high on longer trips. I placed my order over the phone with Suzanne Evans who provided excellent customer service and answered a multitude of questions that I had regarding longevity of the product and install nuances. Shipping was free and package arrived in three business days to TX. Box was nicely packed with all parts individually wrapped and protected along with the POH supplement, 337 forms, STC and detailed installation instructions. Installation was done by my local mechanics, Gafford Aero and took roughly 6 or so hours, far less than the predicted time of 10 to 12 hours. There seemed to be no real struggles other than removing the old elbow with the fixed "waste gate" bolt in it (see dents in the old elbow from tough removal). Upon first engine start after the install an immediate difference in throttle position was noted and power during run up was made using far less than the previous "normal" amount needed. Will be flying this weekend and will report back on any notable differences in the air. Although others have discussed this part, thought I would share some pics with those who haven't seen one or were thinking of getting one on their bird.
