i have a rebuilt to stock spec a6 block and a z6 head. new rings etc... but all stock parts. compression is 9.7 to 1 , ill be using an fmu (12:1) and high flow fuel pump. i wanna know if i can safely run 8 psi on this setup or should i keep it around five? it will be intercooled too. FMIC..

 

we run 8-10lbs on those motors stock without any issues. so Yes 8lbs is fine.

keep in mind its all in the tune and the efficiency of your turbo kit.

good luck.
