While waiting for the new motor to arrive, I was bored and decided to build a knock sensor.
Anyone who is going to tune their own motor should AT THE VERY LEAST have something like this to monitor knock with while on the dyno…
Parts I picked up from my local hardware store
3/4" copper pipe
a couple brass fittings
hearing protection headphones
a small funnel
some 1/2" tubing
epoxy
The photos tell the story…
