The smog pump does not move enough air to make a difference. It might supercharge a lawn mower but not a V8. Any extra power you feel is probably from less engine drag. I once had an old Datsun pickup and when I disconnected the smog pump it felt like an extra 50hp. It ran like a scalded cat after that. I never fully understood why.
