I did actually see this post and others on wilfedo ricart but it never mentioned much infomation on the alfa 162 and harry ricardo and also how it inspired peter berthon for the desgins of the brm v16 i just wanted to share this information i have learned for anyone that doesnt know about the car. jake chapman
according to the book there were several parts of the brm v16 engine that were based on the alfa 162 ''an expetinal feature for the v16 concepetion in 1946/47 was its use of hairpin style valve springs; pairs of springs reasembling those used in clothes pegs. advantages were a reduction of a resonant mass and less height than coil springs allowing shorter and lighter valve stems and a more compact engine. this was a feature borrowed from the alfa 162. also following the afla 162 design was finger type cam followers were specified, with a sized ball at the top of each valve stem to set running clerance.
I frankly doubt that this design had much significant influence upon the BRM concept. Berthon was far more focused upon German innovation than Italian.
I certainly cannot recall finding very much reference to the 162 amongst the reams of paperwork explored during research for my BRM Saga Volume 1, covering the British V16. Neither did Raymond Mays nor Harry Mundy make memorable mention to me of any such influence...

the article says this . peter berthon and raymond mays etc.. were thinking of ideas for a engine they thought of a v8 but they said it was copying the tripoli mercades. then they thought of a v12 based on a m195 mercades engine but then that was aborted until finally peter berthon was inspired by the alfa 162 engine.. the article says ''more concrete inspiration in 1939/1940 in the form of a fantastically complex 135 degree 3.0 litre v16 built by alfa romeo, under its ultra creative engineering chief wilfredo ricart, with the consultation british engine expert harry ricardo''. i also very much agree with about them being inspired by the germans as of course they were superior during the 1930s. but this alfa must of played a part if features from the alfa were borrowed and used in the brm v16.
I don't think that Karl Ludvigsen is making any claims in BRM V16 about Ricarts design influencing Peter Berthon and the BRM engineers in the design of the BRM V16. In chapter 2 of the book he mentions some of the most startling engine designs of the period including a Massimino designed V16 for Maserati which never advanced beyond the drawing stage. To my mind Mr Ludvigsen is attempting to set the V16 design against a back drop of extreme examples of what other designers were thinking just prior to WW2 rather than what directly influenced the design team at Bourne.
yes karl ludvigsen did talk about other v16 engines around that time but specifically said that peter berthon was inspired by the alfa 162 engine as i said to doug above.
i did want to make this topic to be foucsed on the alfa 162 but thank you for everones response about how its related a bit to the brm (makes things a bit more fun i suppose). -jake chapman
