Rotrex C38R
I have seen many people running the JRSC C38-81, but no one running C38-91,92,R on the FA20.
Is there any reason for that? What difficulties / differences are faced with running them? Do they run the same boost on the same pulley as the 38-81 or higher boost? |

Differences in all the 38 models is inlet and max pressure rating. All the rotrex unit’s are capable of a range of power so unless you are already maxing one model out there is need to go to a bigger one. Most people buy rotrex units as a kit from a company not the blowers themselves from rotrex and I don’t think anyone makes a kit with the 38r because it’s more expensive and the 38-81 is sufficient for our motors. It’s all in the handbook. https://rotrex.com/wp-content/upload...l-Handbook.pdf
