Thread: Pro-Jection 4D CFM

    Default Pro-Jection 4D CFM

    Hello, I took in a traded Pro-Jection 4D. Looks fairly complete with wiring harness, throttle body, control box, but I don't have a wiring diagram. The throttle body blades have 117 on the butterflies. Can you help me with what CFM it is? Any help would be great. Thank you and God bless.
