Boost vs Power?

This is in regards to turbo systems and words I've read online. All I am trying to understand is the principal behind this and what I should worry about.

My questions is whether I should worry about boost or power made from boost.

I've read about turbo setups pushing 650 with 9-10psi and others pushing 650 with around 6psi.

Does this really happen? If so, should i watch power made or boost made when it comes to trying to make my 2014 GT engine last as long as it can in stock form?

Thanks for any help!

Have a good tune, don't over boost and keep the rwh in the 600-650 max range and you should be fine

A correctly installed and operating turbo system in the range of 6 to 8 psi is not (should not?) going to hurt anything......providing you don't constantly drive it like you stole it, and abuse the stuffings out of it.
Turbos are actually one of the power adders that are easier on the engine internals than some others. There is NO additional load on the engine (unless you power brake it) off the line, and as the turbos spool up, they add additional stress to the internals progressively, and to an engine that is already rotating. The EcoBoost engines in the Ford family are all up in the mid teens for psi, some in the low 20's for over boost for a few seconds, though they all have forged internals and were designed from the get go for this kind of stress.
Don't cheap out on your BOV's though.

Boost is just generated by engine restriction and the A/R of the compressor. You can't just say, compare directly the Paxton head unit and GT series turbo boost # for boost number.

Turbos make power better than superchargers with lower boost levels bc they take waste energy to run them. SCs try to make up the gap with steep step up ratios in the drive.
