dynamics nozzle

[famousg]

i just bought a jet dynamics reduction nozzle 82mm is this a good bore or should i bore it to 85mm. i have a stock pump with a 9/17 hooker 7mm back set and soon to have a freestyle pump cone. so what bore would be good?

An 85mm nozzle will make more thrust unless the load is already too light with the smaller one.
