2nd Gen Non-Engine/Transmission Amsoil Ea filter

[Vaughn MacKenzie]

I made an Amsoil order this week and thought I'd try the Ea080 filter I've read about, but after looking at it today I'm afraid to put it on. There's 6 dinky oil flow holes versus the 8 large ones of the Fleetguard line. Is the Ea080 the right one to get?



I did some measuring & calculating to figure the total combined cross sectional area of the flow holes. The results were more dramatic than expected and I had to remeasure and recalculate to make sure I wasn't making a mistake



Results. . .



Ea, with 5 holes at . 23" and 6th hole (one larger than the rest) at . 31" gives

. 283 sq in total



Amsoil, 8 holes at . 37" diameter gives

. 860 sq in total



That's more than triple the cross section area, something to consider on an engine with an oil pump that flows 22 gallons per minute. I would have concerns about more oil being bypassed during cold starts, but more so concerned with adequate piston cooling when pushing EGTs towing or playing. Food for thought, don't know if many of you run the Amsoil filter. . .

This has been brought up before. The EaO80 is the correct filter.

The media in the EaO80 is higher flowing than the fleetguard, therefore it doesn't need the entrance holes that a Fleetguard needs.

The Donaldson ELF7349 is the same filter, just different paint, and it's what I run. It flows plenty of oil. I monitor oil pressure on the drivers side of the block and it's never an issue. If you are concerned call Donaldson and ask for the flow spec's.

They are the best full flow you can run.

That's good to hear AH64ID. I think reading oil pressure from that location is a little ways downstream of the oil pump so you should know if there was a real restriction. What kind of numbers do you usually get starting up cold, and at operating temp? Is it a mechanical gauge?

 

[AH64ID]

It's an electrical gauge. I see about 70 at cold start, it will get to 80-85 at 2K rpms when really cold. Normal operating pressure above 1500-1600 rpms is 50-60, depending on ambient temp and if I am towing or not. Normal idle is 20.
