Objects on stove may be larger than they appear. :o

As the pictures show today I finally disassembled and cleaned my oil pump.

I have rebuilt a lot of oil pumps before including high volume big block pumps but the size of this thing just amazes me.

Its actually two pumps in one; A scavenge pump to remove oil from the motor and send it to the 12 quart oil tank and another pump that sends pressurized oil through the coolers and the motor.

I have read somewhere that these turbo pumps can move a quart of oil every couple of seconds and I would believe it by the look of this thing.

Since the 930 uses oil as a cooling fluid an abnormally large oil pump is a requirement.

Those german engineers never cease to amaze me...And you car is like 15 years old isnt it?

 

Actually its over 16 years old.

With the exception of the beefier design of the turbo motor (the new 911 Turbo, GT2 & GT3 still use the 930 lower end) the porsche flat six is about 40 years old.
