Default How much boost can i run at 9.8:1 without meth injection on 93?

Think I can hit 10 Ib's safely? I know allot depends on the tune if it will be safe but do you guys think its possible? It's an AES 390 and s488 turbo. Thanks

You should be ok on 10lbs. I ran 9lbs but with only 91octane (California) and I probably could have turned it up a couple of pounds. No meth obviously.

Need more info on the setup. For instance is it intercooled, what size injectors ect.

I have ran up to 18 psi on 93 octane with a A/A intercooler and a S480 on 364 ci. 80 lbm injectors and twin GSS340s in the tank.

Think I can hit 10 Ib's safely?
To answer your questions 10 psi is very safe on 93.

Yes intercooled (A/A) and 180Ib injectors and dual 340lph pump how far you think I could go without meth. I plan on switching to e85 later that's why I'm going overkill on the fuel system
