Acceleration: F40, F50, Enzo, CGT & Veyron

Yes, agreed but I think you are referring to the top end of the power. Power achievable only behind hand made care. Ferrari checked every engines and they does not deliver if engines aren't within factory goals.

To deliver engines factory goals are usually within a percentage of +/-5% the designed goals in two main points of the curves. Power and torque points. And just +/-2% of the remaining of the curves. I'm not who say this, this is behind EUR-Lex legislation.

Working with particular handmade care, an engine can overcome this highest parameter if work was correctly done.

 

Concerning the Enzo's engine, according to EUR-Lex law, factory parameters for the "power" delivery (simply one of many parameters to check on the curves) had to be from 627 HP to 693 HP if the figure claimed was 660 italian HP.

An engine would have been discarded if checked at 625 HP (or verified lower just on one single curve point) as delivered if checked at 630 or 690 HP. That's a very wide tolerance of delivery. That's a very wide difference in performance even I think Ferrari usually fixed the goal to low threshold of the tolerance, obviously, more handmade careful attention produce even better numbers than the top and that is, I think, what was happened during your engine rebuild, Bill.

I have a friend that works inside Group Fiat and his friendship was very close to the Ferrari engine department. He said me, few years ago, that Factory press Enzo's engines were delivered rated very high, he remember an engine was delivered at 687 italian HP.

(I think that the frequently figure had to stand around 640-650 italian HP..)

Coming back to the F12's engine, if the absurd was to deliver engines with 740 italian HP as top end of the power, Ferrari would play foul about declaration, but could deliver its engines until the low threshold of 670.

It SEEMS to be.. the most recently test seems to be just sligthly faster than the fastest 599s (close to 651 HP rated?).

That's a neat video Bill. At the 4:10 mark in the video, the commentator seems to indicate the GT-R engine takes "…up to 6 hours…" to assemble.

In another video, by National Geographic, it says it takes the single Ferrari factory assembler 5 days to assemble an FF engine.

Several copies of this video exist on YouTube and in the highest resolution HD copy (shown below), that comment comes seconds after the 26:35 point, where the commentator begins to describe the assemble process. At an earlier point, seconds after the 23:37 mark, the commentator says "…it takes 35 days to create just one (FF) crankshaft…".

They must be starting 35 days when the bulldozer extracts the ore from the ground...

 

I think the aluminium comes from Canada but it's National Geographic after all. If they did get the timing correct, they meant "elapsed time".

 

Very interesting Bill. Thanks for your data panel.

 

thanks a lot
LF's data come from speedo, not from vbox, right?

 

Nice video, thanks for sharing.

 

The Motor Trend 1/4 mile time for the P1 is 9.8 and not 9.5.

 

0-180 in 15.44s????????? I'm assuming those green value are projected? P1 does it in about 16.8s from what I've read so a full second fast seems.... a bit crazy.

 

Is Italian HP different from German HP or Japanese HP?
