Advice - delete the smog pump?
I'm new to this forum still and my son has a 1988 base firebird V6 2.8L.
For now the V6 is good, as its not too much power for him, especially since its a manual 5 speed. I was wondering about the necessity or HP drain of the Smog pump. We don't have emissions testing and I have read on other threads that the newer cats don't need this smog pump feed. I know the basic role of the Smog pump but looking for a little insight into this.

No significant HP drain, I would only delete it if it was seized or broken.

Komet has it covered. If the pump spins freely with the belt removed, the power drain is far less than an alternator, and possibly less than a water pump. Removing it will gain nothing but a little space and potentially require an additional belt and idler.

They really don't consume much of any HP...
Plus you can make it into a Vacuum Pump in the future if you swap a V8 into the Car.
