     Bruce Turrentine cut away part of the breather system on the RX8 engine Tracy
     is using. Here is an illustration of what was cut away.

Paul,
 So Bruce removed the entire long pathway below the filler cap?!

Correct. PL


Seems like radical surgury for very modest weight savings, and
possible breathing difficulties. Tracy, how was that lower opening
closed? Welded? Liquid steel?  Was there some other reason for
the removed material? Has Bruce been doing this for some time or
was it an experiment? Pardon all the questions, I'm trying to
understand the need for this mod.
