I asked this a long time ago and never got a reply. Why are you asking?

I don't have first hand knowledge, but I've seen on another site that the 2 barrel version of the GM TBI will flow 490 CFM. Since the Fiero has only a single injector, I'd say it is reasonable to say that ours will flow about half of that.

The Holley Intake and TBI available back in the 80's had a slightly bigger bore and had a modestly higher horsepower claim. (Though I can't remember ever seeing what size injector that Holley TBI was using).

I believe the Holley TBI was rated at 300 cfm.
