put the stock oem clutch fan back in with the shroud.

Stock T28 can do 17psi (it did on my friends)
Assuming you have all the supporting mods
i.e fuel pump,fmic,etc

8psi is weak city
I would run 1 bar on a daily setup.
(I did'nt really need even more)
And like I said about 17psi for the more spirited driving.
