Hi Jim,
Per our discussion of power and torque of our 2 inch OD
1.875 ID P-port engines at 6500 RPM here are the Mazdatrix
dyno curves using a 51 MM weber. Dave and John had the
carb set up properly in ten minutes :)

No EFI and slide throttle data yet as we don't have Tracy
Crook's EFI system tuned for the p-port
yet. His EFI system is designed for a prop load only with
intake air temp, MAP and RPM as the only inputs so
it is difficult to tune for full load through out
the RPM range such as happens on a dyno.
