The offenhiesers were Indy car favorite for years, doubt any of them

over 200mph at indy's 2.5 mile rectangle.

The turbo Offys didn't, but the engine was originally
designed for dirt track (sprint) cars, and those
engines ran on pump gas, as did the original Indy
Offys. By the time turbos came in, gasoline had been
banned at Indy for safety reasons, and all the engines
ran on methanol.

Fast, but could it make right turns?

If it was a turbo Offy, yes, altho poorly. Before
the turbos the Indy Offy was a "lay down" design,
with the crankcase on the right and the head on the
left. Turning right with those engines would lead
to lubrication failure.

The dirt car Offys turned right surprisingly well:
