With 0w20, I was seeing low 40s psi at redline and any temp above 105 C. This was probably fine (my UOAs said it was) but I always eased off when I hit 116 C and let it cool. So basically I could get 3 or 4 turns in the upper rev range. On 5w30, I see mid 50s psi up to redline at 118 C and can hang out at high rpm enough to tail a hard running K20Z3 for 15 minutes on a twisty road. Not a track day for sure but enough.
Read that thread on oil pressures. Not seeing the pressure sag at redline with 5w30.
