My point, regarding 180 cranks is, will a 3 main crank, possibly offset some of the vibration and harmonics that the 180° crank generates?CamKing wrote: ↑Thu Aug 04, 2022 2:47 pmThe Cosworth, and Ilmor engines were also 180 cranks.frnkeore wrote: ↑Thu Aug 04, 2022 2:31 pm A successful 180°, V8 engine, was designed over 80 years ago, the Novi. It ran at Indy, for 23 years, with only three engine related failures. Magneto, one broken crank and one piston. Excellent record, I would say.
It was a 181 CID engine, three main bearings, with a large centrifugal, crank driven supercharger. It started out at 450 HP and ended, with 742 HP.
Maybe 3 mains are a advantage for 180° V8 cranks?
The Turbo AMC V8, and Turbo SBC my dad developed for Indy were also 180 cranks.
A certain IRL team made a 180 crank(and cams) for one of their N.A. GM engines. They ran it during practice, and the sound was so different, everybody at the track knew something wasn't right, so they didn't try to race it.
It seems like it would make it worst but, the Novi, didn't seem to have any problems.
