The Pokigrons actually tend to stay smaller unlike the Suri basin boas. An 8 foot female, Poki would be on the rather large side and a nine footer would be huge. My friend here has a 10-11 year old female that is 6.5 feet that he just bred this past year and his male that is 9 years old is a bit under 6 feet.
According to Gus Rentfro and Stockl, the average female is 6.2 to 7.2 feet, and males a bit smaller.

As Sauzo said the sizes can vary from snake to snake. I like the fact he keeps his girl in a T-25. Gina is a beautiful snake and she will utilize what he gives her for space.
My friend keeps his Pokis in 8 foot cages and allows them a huge temp gradient.
So Charles, if you are looking into the subspecies, plan on doing what Sauzo did and give some space.
Gina is smoking hot! That pattern is beautiful and clean.
