Hi all,

 

Yesterday when I sent the LML post = about the Legacy ram air scoop installed in N27RM, I was still so happy with = the results of how N27RM flew that I forgot to explain how it = works!

 

As you saw from the two pictures on = this URL, http://www.lancaironline.= net/pix/brice  the scoop inlet is in the forward cowling = inlet on the left side, and the filter sits at right angles to the air flow from = the ram air inlet, and above the alternator pad.  I could detect no loss of cooling watching carefully on my CHT’s.  No difference with temperatures comparing left side to right side (#2 still is the warmest = of all cylinders, as it is in 199L).

 

The design allows use of either = filtered air or ram air with a piano wire type push pull knob operating a damper = valve in the plumbing.  Pretty simple.  I am still operating with = pure ram air since Lancair did not have the push pull cable available when I = started flying, and my damper is safety wired open.  No work necessary to = the cowling, and the only drawback is that the aluminum scoop is visible when looking through the left side forward cowl opening.  I don’t have = mine polished yet, and it will look fantastic when it is polished = properly.
