what you think how much boost should i put up and how much hp you think it will make hp is safe on pump gas

[Pank]

you could run 10 lbs boost no problem, all day long, on 93

Yeah the bottom end is not going to be a problem, that sucker will hold up. 91 octane is as good as we get out here, but I am sure you could run 1 bar all day no issues. At 1 bar you should be around 320whp give or take.

Aside from that I don't know what the max safe boost on 91 octane is.
