generally it is 2.5 times the spring.
so, 20 theoretically.
nasteboyii tamed my t3t67ho with a 10 psi spring and a 38mm gate to 30 psi.
it can be done, but on higher boost it may be prone to spiking or may fall off.
if it is a fully built motor, you can run a .8 .9 bar spring on pump. im running 33-34 psi on a .9 spring.

it's 2x the spring pressure or a strert car,
you will want at least a 15psi spring
