Amsoil EAO76 is about 1.4qts and has a 20 micron rating. With that amount of surface area of high flowing synthetic media, I doubt it will have any difficulty flowing what you require. I run my 522 to 6k and I have no problems.

I was looking for the oil flow rate. As in GPM.

In speaking with a professional racing motor technician/engineer, he pointed out the importance of the flow rate over the micron filtering capability.

Getting all of the specifications on a selection of racing filters has been quite a job. And, when a flow rate is given, most do not list "at what pressure" "the visc of fluid" "the temp of the fluid".

Do you guys really know what filter (beyond the name and model #) you are using on that expensive motor of yours?

anybody know???

Looked on the Amsoil site and could not find a tech sheet on the EAO24 oil filter. Help. Does this filter truly have a 3/4 NPT fitting?

The Amsoil EAO24 and EAO25 are more or less interchangable. the -24 is longer with maybe 25-40% more capacity. the 25 is commonly used on boats and GM V-8s in cars and light trucks, while the 24 would be found in 2500 and up trucks with GM engines. I think the EAo25 is what would come up if you did a cross reference on the more common Merc V-8's in boats. The -24 seems to fit fine on installations where the filter is upside down. On older motors the -24 is a tight fit- you might have to loosen the filter mount bolts when changing it but it otherwise fits. I use the -24 for both of my boats.

Perhaps I over simplified the comparison, both filters are designed for the same motor, but there are design differences between stock and racing filters. The key difference between most stock and racing filters is the filter media. In order to increase flow as required by a high performance engine, filter manufacturers use a media with more open space per square inch to reduce back pressure. This of course allows larger particles to pass through the filter, in the links you so graciously provided, I noted that the stock filter is a 21 micron filter and the racing filter is a 61 micron rating. The key to selecting an optimal filter is to find one with both high flow capability and smaller particle filtering. This is why I prefer the Amsoil / Donaldson filters, the synthetic media they use has a finer fiber which allows them to keep the mesh size small but still provides the open space per square inch desired for higher flow.

Someone should write/call Bob Teague and see if his website information is correct. These spec numbers on the HP6A Fram oil filter are great.

Summit Racing has the same specs on their website, except they do not mention flow rate.

Summit is about $ 10.00 cheaper than Teague and you can also buy them on Amazon for about $ 17.00 each.

speed channel had a car show that featured a new fran filter,,,i think it is the one you are taking about,,,better flow with better filter qualities

I just talked to Melling tech support and Amsoil tech support. The Melling 77HV pump will pump 9GPM at 7000 without any restrictions. They figured it's more like 6GPM through the motor. The Amsoil EAO76 filter is rated at 10GPM minimum. These numbers are all based on a number of other factors such as oil temp, viscosity, engine clearances etc.

FWIW

Anybody use the shell rotella disesel oil 15-40?? Also looking on amsoils website and they have 15-40 but only says diesel oil can it be used in 454's

If you want the AMSOIL 15w-40, use the AME 15w-40 Marine/Diesel.

Thanks so could I use the shell rotella 15-40 disel oil in the boat. I use it in my truck and I know the oil is bullet proof. Just wondering if it has all the correct ratings
