Here is the BB engine, finished up and running on the stand with a link below to see it on youtube. No leaks! Needs a little more tuning but this is the second start up and it ran very well. Since this video was taken, we dialed in the carburetors and it sounds amazing.
We received some questions after posting the video below about calling the 512BBi motor a flat V-12. Mainly, if it is flat, then how can it be a v format?
The answer lies in a technicality. The moniker “boxer” refers to the piston timing of an engine, rather than the direction the cylinders point. On the Ferrari 512, the crankshaft isn’t a true boxer crankshaft – it is a V-12 crankshaft with the cylinders laid flat. Here’s why:
True boxers have one crankpin controlling only one piston/cylinder, and 180° engines share crankpins.
A true “boxer” (horizontally opposed engine) has corresponding pistons reaching top dead center simultaneously.
A 180° V-12 engine has piston pairs sharing a crank pin on the crankshaft and reaching top dead center half a crankshaft revolution apart. Most flat 12s are actually 180° V engines, including the Ferrari discussed here and the famous Porsche 917 racecar.
Interestingly, phase has always been of great concern to the motorcycle industry (think big bang configuration) as it directly effects vibration and riders sit right on top of it. Read more here.
We took the red 1960 Ferrari 250 GT to the dyno earlier this week. This is a Pininfarina bodied convertible and is more beautiful than a high-school cheerleading captain. Still, its very close relative, the 250 California commands a much higher price – most people can’t afford to tell the difference. This 250 GT has an amazing sound that’s enhanced by a tasteful aftermarket exhaust, though nearly drowned out by the carburetors at full song – turn it down if you’re at work.

We took the red 1984 Berlinetta Boxer to the dyno this week. The video has great sound, but turn it down if you’re at work.
A Ferrari 250 came into R.P.M. with some major oil leaks. We removed the engine and tested it so we can see where the leaks are coming from. Here you can see the engine running on the test bench. Here is another clip as well. If you like these videos, check out our YouTube Channel at http://www.youtube.com/user/212Fontana.
OK, the wait is over, the HP and torque results for the 3 Ferraris was as follows.
330 GTC. 287 HP and 284 Torque. See the video here.
Daytona Coupe 337 HP 315 Torque. See the video here.
365 Berlinetta Boxer 328 HP and 288 torque. See the video here.
I will work to put the graphs on the blog later this week so you can see the HP and torque curves. It was interesting to see the peak torque curve on the BB to be at under 4000RPM!
