HFC Engine Damage?

4r3s · 08-14-2010, 06:21 PM

Im not a mechanic by any means but it seems like to me, if this were to actually happen, a regular cat would have a higher likeliness of clogging and spitting **** back than a hfc that is designed to keep the exhaust flowing more easily. Or am I missing something here on how the two items are fabed.

well, higher/faster flow can go both ways so, logically, it would be easier for something to be sucked back in a HFC vs OEM...

"There is a time when both valves are open and the vacuum created by the intake stroke can pull a small amount of the debris from the cat. The debris will damage the cylinder wall and create an excessive oil consumption."

I've heard of turbo cars sucking up the broken end of an EGT senor in the downpipe and damagine the turbine wheel.
