is there any power difference b/w the 1500 and the 2200 if your running 8-9 psi? i know the 2200 will get higher boost levels, but will the 2200 have a more powerful 8-9 psi?

Actually there is, but probably not like you're thinking. If both blowers are running at the same boost level, the larger blower will not be working as hard and will have less parasitic loss. With twin screw blowers, boost measured in psi is a side effect. They are positive displacement super chargers meaning that they displace a specific amount of air per revolution. The 1.5L blower will have to spin more times to produce the same side effect in pressure that the 2.2L will. So you'd be running a larger blower pulley and spinning the larger blower slower to produce the same boost pressure as the smaller unit. Also worthy of note, is that the discharge temperature for the larger blowr will be a bit less than what it would be for the smaller at a given boost pressure.
