Just a bit of free information.
On the test stand comparing 181's, 024's, and the Weston style moded 131's
at minimum rack, mid plate, and full plate(21mm). 181 values are baseline.
at min the 024's are +10.6%, mid +4.6%, max +7%.
modded 131's are +23.4% at min, +15.4% at mid, +11.7% at full rack. So if your pump is putting out 500cc with 181's at full rack, 024's would be +7% or about 535cc. The modded 131's would be +11.7% or 558cc.
