Ask Sarah: Rotary Engines and turbo blankets
"ADDED BONUS- As you also pointed out, keeping heat contained in the exhaust manifold and turbine housing will also keep the exhaust gas velocity high which for turbo cars, helps spool the turbo and cash in on that scavenging effect. It can even be helpful in naturally aspirated engines, where a good velocity exhaust stream keeps the exhaust gas flow high and develops a vacuum behind the closed exhaust valve that helps with scavenging when the exhaust valve opens on the next cycle."

"Ignorance is bliss. Rotary engines aren’t unreliable, they’re finicky. They’re like a high maintenance girlfriend - as long as you keep her properly lubricated and ride her real hard; wait, maybe that’s a bad analogy… But I make a good point. It's just that a badly tuned piston engine might go a few hundred miles before calling it quits but a poorly tuned rotary engine might not even get down the street. "]
