I dubt. The felt sack is remarkably breathable. Trying to blow trugh it feels no resistance what so ever. Plus, back when l had a wood gasifier on the MB l only used 2 small wet cyclones as filtration, they expelled sooty fog from the gas. Allso, l had no problem with idle/takeoff with chargas and sack filter combo. Its just the wood gasifier that caused me problems on both MB and Chevy
Thierry, l am not quite folowing. You mean you wuld push the air in the gasifier?
