Is the Turbo Compressor Wheel Diameter 2.24/3.00 in inches?

[Sleepr DSM]

When a turbocharger's compressor housing lists a wheel diameter of 2.24/3.00, is that in inches?

For example, check this link:
Turbo Stats


If that is the case, does the 3.00 refer to the outer diamter of the compressor wheel?

If it is inches, and I converted the 3 inches to millimters, the wheel would be76.2 millimters in diameter.

Am I way off on this?

 

[NOSLO2PT0]

yes and yes

So the three inch wheel is 76.2 millimeters?

 

[pneumo]

yes. you're not way off.

Like I posted on DSMTalk. 3.00 is the major compressor diameter (exducer) and the 2.24 is the inducer diameter. The size of the wheel is based on the inducer. This is a 56 trim wheel you are speaking off just by going off those 2 numbers.
