I have two identicle gauges plumbed inside car.
Oil cooler bypassed!!!!! with a union all hoses and remote mount still in place.
Oil at 100C and 5500 rpm I get 68 psig on remote filter mount after filter and 52 psig at block. Identicle gauges read at same time driving down road. 16 psig fuking pressure drop in the hoses to block. remember my one pressure gauge is on the back side of the remote filter after filter and housing.
I have got to get rid of the fuking hoses!!!!! How the fuk do you get the remote manifold off the block there not enough room for a wrench and it appears you need a gigantic socket. the problem is still in one of the 10AN hoses or they are just to small.
the pressure reading on the remote filter location would keep going up if I didn't hit the rev limiter solid as a preacher dick.
for grins the pressure drop across the hoses when cold at idle (800 rpm) is 10 psig!!! get rid of the useless
oil coolers and plumbing they are destroying your engines.
