Interesting thread... My spontaneous suggestions in the "British section" were mentioned already, the Napier Deltic and BRM V16. The "boat anchor" BRM H16 maybe... Italy: Ducati Desmo, I didn't think of that, but very interesting... My ideas would have been the Alfa Romeo Tipo B straight 8...

Being a fan of the team since I watched Prost vs Senna in 1990 at 10 years of age... Since then, following every season with interest. Have been at the test track in Fiorano in 2007 with my Formula Student team back then (we had to sign various contracts before, quite literally saying that if...

Hello... Nice, and very interesting project! It kind of reminds me very much of my own, the type 35 Bugatti engine... Only that I work on mine since 2013 (not continuously, of course, but there are a couple of 1000 hours into research (most of them) and CAD work). Based on my experiences, a...

Hi Doug, and thank you for the kind words! Yes, with 1/4, things might become a bit tiny... 3 valves with a 15 mm bore - also the fasteners, a lot of M6 and M9 in this engine, which scale a bit better in 1/3. Design- and "re-engineering"-wise, things get interesting when you come to cylinders...

Hello! As a long-time lurker here, I just had to post finally when I saw another Bugatti project in the works... Really great so far, nice to see the CAD pictures, and waiting for further progress! I am working on a Type 35 engine myself, bit older and much smaller at 2 or 2.3 liters. In my...
