Hey guys, I have a 46T compressor wheel on my older (small shaft I guess?) Turbonetics T3/TO4E hybrid. The inducer is 2.003", the exducer is 3.2", and the effective height of the blades is 1.125". Going by their catalog online, it IS indeed a 46 trim wheel, but using the formula found all over the web:
Inducer^2
-------- *100 = trim
Exducer^2
My trim came out to 39... WTF?
What's going on here? Is this something weird that makes hybrid measurements different? Like, it's a TO4E 39 trim, that we call a 46 for some reason?
I hate misinformation.
