Andy,
When you swapped power steering pumps make sure that your pulley is fully seated. I had this issue recently and figured out my pulley was A) bent and B) not fully pressed on. So for safety measures i found a short bolt and washer and torqued it as well lol nothing like that pulley backing off when the motors zinging to 7700

And now a little noob update... who wants to guess how much power this was robbing? I decided to inspect after a few runs to make sure things were good. Crazy to think how violent it was with such a bottleneck/crimp in the "line" lmao. Drove it this morning after adjusting the piping and making sure they flow straight... I can tell you I already notice a big difference. The power delivery is far more instant.
Sorry, I still don't have dyno numbers. I'm broke at this point. Still saving the $500/$600 to get this thing properly timed. I have my AFR dialed in however via wideband/HPTuner road tuning. Nice 11.5 AFR at WOT past 105 kpA.
Enjoy the monstrosity below:
It looked fine on install - but I guess once you put pressure/vacuum through it, the weak spots/bad bends will show themselves. This has been adjusted/fixed.
I'm guessing about 30% to 35% airflow restriction. (Twin intercoolers. The picture above shows a pipe from one of the intercoolers. Hence my 35% guess, because in theory, at most it could only be 50%)
Andy!
Been waiting to see how you are going with your project.
Glad to see you are extremely happy with the camshaft I specified for you.
I am surprised at 3500rpm the engine is already going crazy. Haha
That camshaft will pull to 6800rpm without an issue.
I hope you have a stout valvetrain and everything matches. (Unlike my engine if you have read my thread)
Once you get the boost working properly you should have a very flat power and torque curve from 3500rpm+
The pro chargers just keep pulling in the top end.

Thanks for chiming in! I was sure to push that f***** in all the way ;-) I got all my belt problems sorted by switching to a manual tensioner. The auto-tensioners are just junk at this point.

I think most of the board is waiting for an update from YOU on YOUR thread sir! :-)

I'm looking forward to it.
In regards to my build I know everyone is waiting.
I'm expecting everything to be completed next week.
Last I heard engine is apart with the new gaskets, lifters and camshaft being fitted.
I should update my thread with this new info.
