piston 2 wall clearences

[CA19DET]

ok i'll be running JE forgies w/ total seal rings, what sort of clearence should i be using, remmber fulkly forged engine, max 30psi, maybe N20. my engine builder i know has an idea of what clearences he wants to run based on JE, Total Seal, the FSM and past experience building race engines..

just want opinions on people who have built engines in the past.

thanks

you should consult the piston manufacturer, they made the pistons they know what's best. You should have got a data card with this infomation and ring end gap when you purchased the pistons.
