High Oil Pressure >.<

people sometimes don't warm up the engine/'oil' and thats when you start seeing 90psi as you shift at 5500 with the engine/'oil' still cold....

Yes more pressure is more parasitic drag/hp loss [lil].

I personally like seeing 35psi or so psi fully warmed up, it just makes me feel good and I think to a point keeps a certain amount of transfer of heat dissipation at the lower rpm where there is not much air moving by....
on the other hand...compressing oil/fulids makes heat, the more you compress...the more heat AND hp loss.

pondering again...
