What is a typcal airflow for the smaller stock frame turbos like the IX, Green or BBKs? Do you have an airflow plot to share? Right now I am flowing 2000 Hz by 7000 and toping to about 2050 by 7500. Is this typical, low or high? I know it is not high but I am not sure if it is low.

Here is a plot of my current airflow. Is this typical? Good or Bad?

 

I recall seeing several posts by Bryan from GST that showed airflow. You may want to search in the Ecuflash section as I believe he was discussing tuning as it related to airflow.

 

Thanks for the hint! I forgot about that. It looks my turbo is flowing about the same as an FPGreen. The plot below was posted by Bryan some time ago. Very similar to waht I got. But I started the log a little later but at full boost it is about the same.

 

^^ Not sure how an evo8 could flow as much as a green .....

 

It is an Evo 8 but with a 20 G and Kelford 272 cams.

 

Here's some early airflow/boost numbers from my BBK:

 

That is some nice airflow from the BBK. That is a BBK Full right? With my setup I think I can't hold 25 psi to redline. By design I am at 22 psi by redline but I doubt I can hold 25. I am now at 92% WGDC and only hitting 22~23 psi by redline. That is with the stock airbox.

 

Yup, BBK Full. Holds boost awesome on the OEM WGA! These are on just pump gas. Dyno numbers are in the dyno section, just search for BBK and my username
