Frequently Asked Questions
Why does the 512 BBi produce less power than the earlier carbureted 512 BB?
The BB 512i switched from four triple-choke Weber carburetors to Bosch K-Jetronic fuel injection primarily to meet tightening emissions regulations in key markets. The transition cost a modest amount of peak horsepower — roughly 340 hp vs. 360 hp — but improved drivability at partial throttle and reduced cold-start emissions. This manual covers both the carburetor setup on the 512 BB and the K-Jetronic system on the 512 BBi in full detail.
Are the 365 GT4 BB and the 512 BB covered by the same procedures?
Many chassis and body procedures overlap, but the two models differ meaningfully in engine displacement (4.4L vs. 4.9L), carburetor jetting, and certain suspension geometry specifications. The manual separates procedures where specs diverge, so you always reference the correct torque values and clearances for your specific variant.
Does the manual include wiring diagrams for the electrical system?
Yes. Complete circuit diagrams are included for all Berlinetta Boxer variants, covering ignition, lighting, instrumentation, HVAC, and — specific to the 512 BBi — the K-Jetronic fuel injection wiring with connector pinouts, wire color codes, and ground locations.
