It is quite possible there are other reasons, but since we don't know the reasons already provided, we can't tell what they are.
Oil pressure ( minimum amount ) is 6 LBS. at 1000 RPMs. 18 LBS. at 2000 RPMs. 24 LBS. at 4000 RPMs. more pressure is fine too.
Flywheel 79.7ft lbs - 85.5 ft lbs pressure plate 18.5 - 24.4 ft lbs
14 lbs = 1 stone. Therefore, there are 35 stones in 500 lbs (with 10 lbs left over). In other words, 35 st 10 lbs.
600 lbs.
the pressure is 1,260.000 lbs per sq.ft.
9 to 13 LBS. NO less then 9 LBS. and no more then 13 LBS.
743 lbs, that's stronger than a lions (691 lbs)
A pressure treated with those measurements will be about 350 lbs. That is more than the common standard pressure treated measurements.
i will slap you
38 front - 40 rear
if you are talking about A/C, then the small connector is high pressure and larger connector is low pressure., low side 80 lbs .( this is static ), low side 35 lbs a/c running, high 200 to 300 lbs.
Force (lbs) = Pressure (psi) x Area (in2)Pressure=Force/Area
