Ok so you are barely working that blower, I don't foresee the spacer doing much for you. If your running a 1-1 rear ratio and a 3.4" front that thing isn't even breaking a sweat.

Any time u can remove heat from the equation from any PD style Blower, hp is readily available. the spacer has always proven to reduce heat soak, in turn reducing your IAT's allowing for more timing to stay in. look at some of those IAT correction tables when those IAT's are up near the ozone without one...
