Hey Paul,
What's with the extra plug on that 4 rotor in the picture?  The plugs are
labelled: 1L (first rotor, leading), 1T (first rotor, trailing), 1FT
(first rotor, "F" trailing?)...

They may have been there in other pictures, but I just now noticed them.

The four rotor had three plugs for 2 to 3% better BSFC. There was a limit
to how much fuel a race car was allowed to burn for the 1991 Lemans
24 hour race. Therefore Mazda not only went faster and outlasted everybody else
but they did it on the same amount of fuel.
