Subject: [FlyRotary] Re: intake manifold porting question
Is it acceptable to use something like Marine-Tex
to
help smooth the ports? Should I worry if a piece of it comes loose? I
plan
on a turbo'd 20B.<<<
Don't sweat the small mis-matches, especially if you're going with a turbo.
If you do decide to use some kind of filler, make sure to roughen up the
metal surface first and clean it maticulously for a good bond.
If I were that concerned about performance, I would have them weld build up
any areas that needed it and then file off & polish any mis-match. If a
piece of anything should break off and get into the engine, you can bet on
buying a new housing, seals, etc., not to mention loosing performance in the
air when it happens. But the beauty of these engines is that they will get
you down safely without a catastrophic failure even if you do eat a piece of
junk.
