This is the type of attention I want to get with my dirty.

On compressor maps, the y-axis is the pressure ratio which is (intended boost pressure + 14.7psi)/14.7psi. so a pressure ratio of 2 equates to ~15psi boost pressure and a pressure ratio of 3 would be ~30psi etc.
On the x-axis, the target horsepower can be approximated by multiplying the flowrate in lb/min by 10. so 40lb/min being about 400whp. You want to land in the middle of the highest efficiency island.
TCD or anyone that isnt a total noob with turbos, please correct me and expound, I am here to learn.

I was not calculating my pressure ratio correctly. 20psi would put me at 2.3 PR and that puts me right in the honey hole for the turbo! Well, maybe I guess.

say goodbye to your teeth
Actually let me know how the vibration is. Better yet, I need a ride when they are installed.
As for motivation. Get some warm clothes on, Get the jack out, put a stand on one side, Get your 12 or 13mm wrenches out, support the trans with the jack, replace them, and be done with it in under 15 minutes.
I dare you.
