Alistair,  thank you for the write up.  My real world experience was
on 1.) Datsun 1200 that through a slight miscalculation ended up with
12:1 compression following a bit of hot-rodding. and 2.) Triumph TR4
w/ a Judson supercharger on a 9:1 compression motor. Spearco's
Injectronic allowed both to run on $1.25 Chevron Custom Supreme rather
than having to visit the local race shop twice a week for +104 racing
fuel at about $4.00/gal. (1974 dollars....)

Water injection works just fine. Make horsepower? No. Allow you to run
compression ratios that ought not work? Yup. Higher compression ratio
make more horsepower? Yup.  Semantics.
