Does anyone have any real flow data for an extrude honed Cobra upper intake?
I’ve searched quite a bit and all I can find is anecdotal comments and speculation. The speculated flow range varies quite a bit, with some stating that “a friend of a friend” got theirs done and it flows 300 CFM/port, while others state that it’s only about a 20 CFM bump from the upper manifold as-cast. Most of the comments are forum posts with no real data sheets to show the flow and port-to-port variation.
Cost aside, this seems like it could be a great stealth performance option for the street when coupled with something like a TMOSS ported lower, but only if the flow comes up in the 260+ CFM range after the process.
