Are you sure about that? I thought unpressurised systems went out with the
square riggers.
A 'blanking plate' is usually a restrictor to be used in place of a
thermostat. It basically replicates a wide-open thermostat in terms of its
flow rate, but without the risks of sticking shut. It is normally used in
competition where engines are fully warmed before use, is going to be run
very hard, and the concept of a thermostat isn't really needed. It's said
that the flow restriction is required, compared to simply removing the
thermostat altogether, as without either flow rates can be higher which can
cause turbulence, local recirculation and consequently hot-spots. Some say
"surely the faster the flow rate the better?" which would be correct *if*
you could guarantee smooth flow throughout the engine and it is smooth flow
which picks up heat best, not necessarily fastest flow.
>From the description I think the poster meant 'without thermostat' as he
talks about it being harder to warm up from cold.
