Ferrari Mailing List: Re: Flat Plane vs. Cross Plane

[Doug & Terri (dnt]

Boy –FG – neve a simple question.  Dunno the answer to them.  BUT:

 

1)      Smokey Yunek designed a flat crank chevy engine.  A  lot of work for 5 hp and even exhaust pressure.

 

2)      Porsche’s 12 cylinder 917 used a Type 912 180 degree flat crank.  Note – this was not a boxer engine as the crank webs shared con rods nor was this the engine in a 912 street car.  The “type 912” engine was a rouse to foil any spies that Porsche was working on a 12 cylinder engine.

 

Let us know what you come  up with.

Subject: [Ferrari] Flat Plane vs. Cross Plane

 

A lot of talk lately about the flat plane in the Mustang GT350 being similar to the Ferrari V8s....

 

Question to the list:

 

Are the Ferrari 12 cylinders flat plane as well or cross plane?

 

I took a look on wiki and it seems that flat 12 came up under 2 cycle cross plane....hmmm.

 

I'm assuming Lamborghini is identical to Ferrari in this regard for their 10 and 12 cylinder cars....

 

Thanks,
