This is a unique website with some great info & histories. I have not read all yet [of course, there is so much here.], but I plan to continue to check more of the histories of the vintage marques. I am familiar with some of this since we go to the Pebble Beach Concours each year, along with the Historic races at Laguna Seca. It is difficult to find the time to do the research needed to assemble all of the background and history that you have here. It is convenient to have it available in one place which is easy to access.

Having just read the Isotta Fraschini story, I have sent a private post to mention a few minor typo or proofreading type errors. This is always expected, and this is not meant as a criticism of this site or the author.

Again thank you for the time and effort that has obviously been put into this website, and please accept the notation of these exceptions in the spirit of assistance with which they are being submitted.

Having just read the Isotta Fraschini story, I would like to mention a few minor typo or proofreading type errors.


In the first paragraph under the "OVERHEAD CAM DESIGN" section, it appears that the following items may need attention.

1. "The per combustion chamber;" Is this intended to say "pre-combustion chamber"?
2. "Camshaft" appears to be misspelled as "camshatt".
3. "Driven" seems to be misspelled as "dnven".

The per combustion chamber; the camshatt was dnven by a vertical shaft from the nose of the crank, with skew gears.

In the second paragraph in the section on the Straight Eight, there is a description of the monoblock being "topped by two three-cylinder heads". If this is still referring to the in line 8 cylinder, I am curious as to the actual construction. Is this a simple typo, or were there 2 siamesed ports like a Model T Ford, or some other device not described?

"The World's First Production Straight Eight"


There was also the threat of two rival Italian super-cars from the Lancia and Fiat factories, both with large V12 engines but, fortunately for Isotta Fraschini, these took a year or two to get off the line, due to labour problems affecting all Italian industry. Even so, it has a strong claim to being the world's first true production straight-eight. The massive engine was a joy to look at and was beautifully constructed, but as a dynamic object it was more noted for long life and reliability than for power or refinement, in the marine rather than the aviation idiom.

The monobloc aluminium cylinder casting was topped by two three-cylinder heads, and the overhead valves were opened by pushrods and rockers. Nine main bearings supported the vibration-damped' crankshaft, which was arranged like two fours in series in the Bugatti manner. This layout was claimed by Cattaneo to provide better mixture distribution, although it was inherently less well-balanced than the 2-4-2 disposition later adopted by Bugatti, in line with US designs.


Again thank you for the time and effort that has obviously been put into this website, and please accept the notation of these exceptions in the spirit of assistance with which they are being submitted.
