91 Octane enough?

[GSteg]

before i go turbocharging my car....i want to know if it is safe to run 7lbs of boost with 91 octane with stock bottom, stock fuel system, stock electrical system, etc ? i don't want to risk detonation. i don't have enough money to upgrade the parts just yet...where i live...91 octane is the highest i can get..

I use 91 octane...no problems that I know of. There are people that would add NOS octane booster to bring up the octane level...so you could do that.

What mods do you have currently on your car ?? Here is a thread aboutturbo setups and what you need with what. If you have any questions about the setups post up in that thread.

everything stock...

Yeah you could get away with running everything stock with 7lbs. You can easily run 7lbs on 91 octane.
