How to Measure Enducer/exducer Size

[supraguy31]

Stupid Question I know but I want to make sure Im doing this right.

Do you measure the compressor wheel blades from tip to tip across for the Enducer and the same for the Exducer.

If there is a link already posted sorry for the Duplicate Q. I couldnt find it.

Robert:
You are correct. Measure from tip to tip. Remember, inducer is the smaller on the compressor, inducer on the turbine is the larger.
