Which one flows more? Ideally I'd like it as a t4 83/74 turbine side

I would run it with a 87/81 1.00AR atleast, or even a 96/88 1.1 for some crazy top end.

The Caterpillar 78mm compressor is 7-blade, essentially just a larger version of the 72mm and 75mm wheels.

I have 2 reasons I want the 83/74 wheel. 1: it'll allow me to swap between my 467, my 480, and this without having to pull the turbine housing, and 2: I don't currently have the fuelling or rpm range to really make use of an 87/81 wheel let alone a 96/88 (currently limited to around 3800rpm.

Plus down the road I can add a pair of gates, and an hx82, and have a decently quick spooling setup that doesn't choke on the small turbine side

The 74/83mm wheel has a hard time supporting much over a 72mm compressor.
