That's too much boost. 180 with an 83 is close to max depending on mods. I have seen 180 with 77 and they are on the edge. There's a point of diminishing returns, the blower will become a heat pump
Good luck
Going with high boost on this blower is a steam machine.Most should be 15.5 to get max gains all your doing at this point is loosing power.It's a stock blower not mean for high boost psi .A 77 pulley setup would smoke a 77 180 on the street ...
Like Hulk said earlier it's beyond the point of dimishing returns. At that point every hp you produce your creating more heat than power. There are other ways to make power that won't turn your sc at 15k+rpms.
That boost chart will change with headers ,filters ,t.b and heads so can't go by that fully it's just a reference
Boost can also read different due to load ,bottom of 3rd gear boost is higher then top of 3rd,bottom of 4th is a little higher then bottom of 3rd etc, my experience anyway,
