I have used solid wires in both my street TRs and my race cars but have had
a couple minor problems with them. When I tried to use an electronic
tachometer there was too much noise from the wires, causing lots of tach
bounce. Recently I had my car on a Dynojet dyno, and the noise from the
wires would not let the computer work. It was not until I rigged up an old
set of resistor wires from my tow vehicle, that the dyno would work, and I
could make my runs.
