I always thought psi blowers were only legal in TAD? But yet Jimmy has one on his Dart. Is he (you) only planning on running outlaw events or....
The reason I ask is my buddy is building something similar and we were tossing around different forced induction combos

What I know from asking PSI is that a C rotor is legal but the D rotor is not. I origanally started with a B rotor that was a gas/alky screw we have recently had them send a C rotor for the new setup.

I will see where they have it in the rules.
