Review on 💥 Enhanced Control Devices CS25 100 Start Valve for Optimal Performance by Colin Watkins

Harbor Freight McGraw supercharger weighing 135 pounds, I believe that's its name. in any case, the cylinder pressure was vented from the head as intended when the supercharger shuts down, but the cold start valve seemed undersized or defective as the supercharger failed to start under load. I bought a 1/4" tee and 2 of those cold start valves and now the supercharger I got for half price ($101) has been remanufactured for an additional $16!
