Thinking single turbo, got a few questions

I pushed my old billet 366 to 65 a couple of times, I think any thing beyond 50 psi you're not gaining anything in a single 300 frame charger.

In this case it had some spray and a lot of gate.
Ill wait for Jacob to chime in but, these trucks pushing past 40lbs is over their limit for the most part. They wont last that long at that level. These are reason as such where HTT and II use internally gated housings to prevent this in most cases. But, since when do we follow the rules 
As far as I know the trucks are still stock LOL

40psi on stock turbos or on a 366?

He's talking the max efficiency range of a 300 frame charger. A lot of people associate more boost equals more power, but more CFM equals more power. More boost will provide more CFM up to a point. Once you push a turbo out of its efficiency range your losing power and risking a turbo failure.

They can, but we offer the 70mm turbine wheel for the 64.5 and 67.7 as well.

The reason most people see failures with box chargers is because they have 3 pad thrust bearings when they should have the upgraded 6 pad that borg Warner makes for certain company's and does not come in there box chargers...problem is everyone pushes these cheap S366 all over the Internet for 699 and don't understand that point
