75mm pulley, what belt?

Hi, I made a custom 75mm for my ESS TS in my m54b30, but like to know what belt length need to use...
right now, have 79mm with (if I remember) 1920mm

What are you up to?

Just reuse your 1920 mm.

When you loosen your tensioner to put your belt on, move the tensioner as far as it will go then fit the belt if the tensioner goes past half of the full travel then drop the belt size by 10 mm.
I will loose boost at the top end if I don't follow this procedure.

So, you want the belt tension in between no movement left of the tensioner and before half way when releasing the tensioner.
