whats the max the oil pressure is allowed to drop when doin hard turns without a baffled sump?
the track i go to assen TT has many right turns and the oil pressure stayed between 4 and 5 bar in corners
is that good?
oil im using is 10w40 motul 300v

 

I'd prefer no less then 50-70psi at a guess. Moments of low oil pressure aren't good for the turbo or engine bearings.
Could add 20-50 and a 1/2 qt over stock to try to compensate until you can upgrade the pan.
A common rule of thumb is anything more then a 200tw tire and 10/10ths driving needs a race fab or infinite pan.

 

i already do the 1/2 t over stock
im using toyo r888r's though 50psi is like 3.5 bar it never went below 4 bar
