Not a safe bet. If you're using more air, then you need more fuel. If you have to spin a 12 lb pulley to get 8-9 psi, then you're moving a lot more air, hence the need for more fuel.
Don't trust psi for knowing how much air your engine is using. Psi is only a measure of resistance. An engine is an air pump. More air out = less air backup for the blower.
