Blue 512BB on Chassis Dyno

admin — Mon, 01 Mar 2010 15:21:00 +0000

We dynoed this blue 512BB last summer, and I cannot remember the exact figures. But, I do remember the incredible torque curve and how it made the maximum HP and torque at 5000RPM then plateaued out. I think it made just under 300HP at the rear wheels. We are going to be overhauling and enhancing this engine soon and it will be cool to put it back on the dyno to see the new numbers.

Here’s a link to a similar 512BB on the dyno this winter – this time in red. http://www.ferraricraft.com/2010/01/video-1984-ferrari-512-bbi-at-the-dyno/

When is Flat 12 a V12

admin — Wed, 03 Feb 2010 18:08:33 +0000

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.

Dyno Testing the 1960 Ferrari 250 GT

admin — Wed, 03 Feb 2010 14:53:04 +0000

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.

Video: 1984 Ferrari 512 BBi at the Dyno

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.

Ferrari 330 GTC engine after overhaul

admin — Mon, 27 Apr 2009 00:08:25 +0000

The link below shows the first start up after we overhauled this 4.0 liter Ferrari V-12. There is always lots of assembly oil to burn out of the combustion chambers so some misfiring is normal. Once the carburetors are tuned and ignition timing dialed in it will be time to run her some more to inspect for leaks or problems. We ran this engine more that day and found everything to be in check.

I am thinking of a chassis dynomometer run on a Porsche 911 with a recent overhaul and the GTC that this engine goes in.

Dyno Results for the 330 GTC, Daytona Coupe, and 365 BB

admin — Thu, 02 Oct 2008 12:47:00 +0000

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!

Ferrari 365 GTB/4 Daytona on the Dyno

Here is the third and final car on the chassis dyno. An early production Daytona.

Ferrari 330 GTC dyno run

admin — Wed, 24 Sep 2008 18:38:00 +0000

Here is the run for the 330 GTC, we overhauled this engine about 2000 miles ago so it has “limbered up,” but we found it to be running slightly lean on the test.

Ferrari 365 Boxer on the chassis Dynomometer

As I mentioned earlier, I brought 3 Ferraris to do some test runs on the Chassis Dynomometer in Burlington. I was very impressed with the results. Ferrari has been known to embellish the horsepower figures of there engines but we found the actual readings closer (not as high) to the factory figures.

Here is a youtube clip of the 365 BB run
