You realize you are going to pile more money on top of the blower kit to get it safely working right, correct?
Little things like boost gauges, tuning, t bolt kits, suspension work and tires are going to quickly add up and if you don't do them, you'll likely end up unsatisfied.
The i1 will never be like a PD blower, you still need load and some rpm to build boost, varying the speed of the blower won't change that. A PD takes a trapped amount of air and jams it into the engine so, can produce mammoth torque at low engine speeds. The problem with that is it loads the reciprocating assembly quite hard so, you have to watch that.
