This
thread has gotten me thinking about things that make rotors stop.
So tonight I removed the an item of concern. There was
a screw inside my airbox (under the filter) holding it down onto it's
proper position. This was due to the shape of the intake hose trying to move it
a little. However the heat from the engine and turbo over the last 50+ hours has
made it sit perfectly without the screw to hold it and once the top cowl is in
position it is captured and cannot move.
But more disconcerting is another mod. Many builders have
done this and that is the plastic steel (JB weld or Devcon) inside the
secondary intakes in the end plates. During my first build I was all ready
to perform this task when I had thoughts about a piece of plastic weld breaking
loose and going through a rotor, so I omitted it. On my second rebuild (after
detonation incident), I went ahead with it, thinking that if anything like this
was going to happen I'd likely have heard about it and also thinking that the
engine would likely just pass it through without incident. Now after reading
Leon's testimonials about things as trivial as a bit of cardboard taking out a
rotor, I'm again thinking about this.
Plastic steel is incredibly tough, but when I need to
remove some, I use my acetylene torch to heat it and it will crumble away in
chunks. Now if the engine is properly cooled it should never get anywhere near
hot enough to compromise the strength of this stuff, would it? What about
on a loss of coolant or other overheat situation. Even if the engine doesn't
appear to be damaged from this, what about the plastic steel?
I'm not being paranoid or anything here, but just asking
questions to promote thought about plastic steel. Don't get me wrong, I think it
is wonderful stuff.
