mquinn6 Posted August 29, 2021 Share Posted August 29, 2021 Ok... looking at my current baffles and reading thru as much as I can - but nobody is really mentioning dumping our cool fresh air OVER HOT exhaust before going up to cool the cylinders. I have had some challenges with exhaust tape on some cars (rotting out the exhaust (even coated)) as well as degrading and putting fibres where I do not want....... What do others think?

Just thinking that you can hold your hand 2-3" from a hot exhaust pipe and it won't burn you so I don't think the heat transfer from the pipes to the plenum cooling air is very great. And anyway, I'm guessing there is a pretty fast turnover of cooling air so the pipes don't have time to heat it up much. Baffles are pretty tedious as is without the extra complication of pipe-cooling--would make them hard to inspect too. It is pretty much accepted not to wrap pipes. If they're stainless, the extra heat makes them deteriorate faster. Quote -KentCozy IV N13AM-750 hrs, Long-EZ-85 hrs and sold Link to comment Share on other sites More sharing options...
