Here are two sets of specs for you

As you can see they don't quite match.

Find the formula and do the math and decide which set of numbers you believe.

Hope this helps:

Trim
Trim is an area ratio used to describe both turbine and compressor wheels. Trim is calculated using the inducer and exducer diameters. As trim is increased, the wheel can support more air/gas flow. Use these formulas when calculating trim

[(Inducer Diameter)^2]/[(Exducer Diameter)^2] * 100= Compressor Trim

Flip it around to figure out Turbine Trim.

If my calculations are right it is between 46 and 50 with the data from the above links.
