What’s overrun? A typical sight on most racing vehicles, and even some excessive efficiency street vehicles.
That is identified if you carry off the throttle at excessive rpm, and the interval the place the engine slows down, throughout which any unburnt gas will get ignited by the remainder of the exhaust system, while the throttle remains to be closed.
Typically induced when operating a really aggressive gas map. However this similar setup generally is a double edged sword. Over fuelling generally is a technique used to chill down cylinder temperatures, however an excessive amount of can destroy the CAT.
It's extremely doubtless this Porsche 934 doesn't have a CAT to fret about, as an alternative it produces an exquisite sight that even NASA would most likely be pleased with.
