Hello everybody,
who has information about turbocharger / turbo turbine wheel shaft:
BorgWarner Airwerks Turbo - K44 Series
I only found this:

Hi Rip,

I don't know anything about that turbo, but I could sure put that 140 mm turbine to good use!!

Hi All

one question to the experts and those who know.

why went in the course of development at the diffuser to a larger outlet?

for example: Phoenix 30.3 vs. GR180

Outlet height: 5,5-7,7mm












and which one is better for our do-it-yourself turbines

thanks Ralph

Hi Ralph

Go with the more modern design

There'll be reasons for the differences, but impossible to say what they are without measuring every part and what the design parameters were with regards power outputs .

I would be interested in how the air behaves at a larger outlet!

basically: the flow velocity decreases and/or the pressure increases?

what does the literature say about it?

thanks Ralph

Hi Ralph

Yep , slower velocity = greater static pressure .................but there are undoubtedly other reasons behind the differences, we need to look at the total engine design

Cheers

One more thought about the diffuser exit

A rounding should improve the flow to the CC inner pipe

In general, every edge in an air stream is not conducive.
