There were also the 312/B/T-s as was pointed out.saviour stivala wrote: ↑Thu Dec 20, 2018 10:30 amI do not recon there ever was a flat-12 engine used in F1 or sports car racing made in ‘boxer’ configuration.
A flat engine which is not a ‘boxer’ configuration is regarded as a 180 degree vee engine.
The problem of a flat-12 used in F1 was always its wide and exhaust ground clearance.
V-engines with exhaust out from in-between the 2 cylinder banks were made and races.
V-engines with inlets in-between the 2-cams of each cylinder bank were made and raced.
The only ‘boxer’ configuration engine I know off that raced in F1 was the 1955 Porsche 547 1.5-litre Flat-4.
Flat-12 racing engine for use in F1 and sports racing cars:- Porsche 360 Cicitalia of 1949. FERRARI 512. Alfa Romeo F1-117/33tt12/33sc12. Porsche 917. Motori Moderni 1235F1. Tecno F1-Flat-12. Mercedes-Benz M291. Non of these flat-12’s were boxers.
I wonder why they didn't went with boxers, what reason is there against it?Edit: Ah your other comment explains it.
Thanks for the info.till.a.fischer wrote: ↑Thu Dec 20, 2018 11:41 amI can only speak for Ferrari-engines:
Flat 12s were used in following F1-cars:
1964-65 Ferrari 1512 (sometimes referred to as 512), 1,5 litre
1970-74 Ferrari 312 B, B2, B3
1975-80 Ferrari 312 T, T2, T3, T4, T5
While 312 T4 won the Championship in 1979 its successor T5 failed miserably.
Two reasons made Ferrari abandon the flat12 concept:
There was no room under the car for a diffuser / ground effect.
Turbo-Technology was on its rise and dominated the 1980s.
