I have put some 10:1 comp.ratio pistons in my 314 cid Cont. GPU.
I know some of the guys say an air cooled engine is too noisy to
detect a knock, But I want something to look at.
A few years ago Mick Myal(sp?) had a schematic for an amplifier/filter
that used an automotive knock sensor.
I lost my copy---anybody have a copy??? Jerry :ermm:
