Turbine Flow Question

In a BW S300 turbo with equal sized housings what is the flow difference between the 68,71,73 turbine wheels? I do not need numbers to within a decimal point just a good idea of the difference between the 3. Also which works better at higher speeds, I noticed the garret 4094 that I had did not like to be run at real high speeds. I do not want a turbine wheel that turns into a wall like the garret did at 40 psi. TIA

Have you read what Les wrote about his new turbo a while back?

Yea I did, I also talked to him about it. Joe also got a new charger that he is in love with, I would probably lean on the smaller side for myself because of towing. I am starting to think my motor would need twins to really move up too much in power and still be able to tow effectively.
