75-'76 930s didn't have a boost gauge on the tach..'77 was the first year and had the 1.5 bar boost gauge. The only 930 to have this style stock. All 3.3 litre cars '78-'89 had the 1 bar boost gauges. Maybe it had something to do with the 3.0 litre motor, but I speculate this tach/ boost gauge was used on racing applications and carried over. The 3.0 litre motors were all similar in HP, torque and boost (bar/psi) relative to US and euro spec models. Boost was the same at 11.6 psi for all cars. The '75-'77 porsche 930s were a work in progress with different styling/ equipment changes each of the three years. The tach/boost gauge being one of those small changes.
