| I put the M52 intake manifold on the flowbench today. Below
are the results and the previous numbers I got from an M50 intake. All measurements were
made on the 300cfm scale and at 28" of water. The unused runners were blocked off, so
the numbers represent the flow from the throttle body opening to the port face. ..............M50..........M52 |
