Hi, I have lurked BITOG for a while.
A while ago I used info I found here to determine which Purolator Gold filter is a size upgrade for my Ford Fiesta ST with the same silicone anti-drain back valve. It worked well.
Now I am getting a big turbo kit which should give me around 300 whp and full boost at a little over 3,000 rpm.
I like doing autocross, open track days and some spirited driving on mountain roads. With 300 whp and that kind of use, the cooling system is very taxed. A radiator upgrade is in my future but not available yet so I want to do what some people have been successful with and replace the oil to water heat exchanger with a Mocal thermostatic sandwich plate and an external Setrab air to oil cooler.
The idea is to remove some of the heat load on the radiator and increase the capacity of the oil cooler system to protect the oil. That combo seems to increase the length of a race session before the Fiesta ST overheats.
What I'm worried about is execution. The anti-drain back valve seems critical for the oil filter, I want to make sure I don't do anything that could starve the oil system or create an air lock.
Unfortunately I have not found any reference that explains the proper placement of a cooler.
I should draw a schematic of the oil system stock and with a cooler so I can get a better idea of exactly what the ADBV does and if my cooler will screw it up.
If anyone has a good reference, please let me know.
