I've put together a real motorsport quality crankcase pressure sensor. It will ready from -14.7 psi (full vacuum) to 30 psi. This is a great way to watch for ring wear and other engine problems. Many Cup cars come from the factory with these sensors installed. This sensor comes harness to connect to an AiM system or with bare wires. The sensor has a Metripac connector on it for easy installation with a socket. I will provide a custom sensor setup for AiM systems or can give the data to people for any other system. The price is $254.90 each. Let me know if people have any questions or would like to purchase one.
