full flow question, anyone make a filter blockoff plate with fitting? Options

[Aaron Cox]

hey all!

fullflowing question.

i have a 38mm pump (yes 38mm) with gears supported by both sides, and a regular cover plate on it. (cant find manufacturer - got it from steve stromberg :cringe: ) i do not know the pump manufacturer, so thus i cannot get a full flow cover for it. i like the larger pump because i have a front cooler and -10 lines.

i want to full flow my motor....
so the passage from the pump that goes diagonally upwards toward the filter and 1st galley plug....
i could tap that galley with an elbow to EXIT the case and go to a remote filter... and come back into the case through the standard galley plug next to it....

but my question- to make it more simple.... and not require two elbows out of the case...

does anyone make a filter blockoff plate with an AN fitting in the bottom passage? thus i would not have to use a second elbow-

Ok,

1. Those elbows are actually 2 45 degree ones -which makes 1 90 - (-not two 90's as you presume.) That makes one 90 + another 90 at the elbow.

2. I never said anything about the CASE passages - that is something only a select few can negotiate around ( making the case 'dry' and running only external lines, believe me it CAN be done and not have a single solitary hard 90 anywhere)

3. Take your pump and look at the outlet hole size (you do not have to measure, it is noticeable to a blind person) and compare to the available diameter of the case passage you want to use - the difference in size is prolific. Do not 'take' my word for it, just look, even on aftermarket pumps the difference is profound...

4. You WILL heat the oil unbelieveably -AND- you WILL cause unnecessary friction and sap energy to pump oil in a pump that has nowhere to go. I can quote physics and all that but will not - the difference in sizes of pump holes vs. case holes says it all.

5. There is a huge difference between a hard ninety and a sweeping ninety. A simple check method would be to take a straight piece of PVC pipe and pour a measured amount of liquid through it and time it. Now put a hard 90 in the same pipe, make it the same overall length and time it again - the results are startling ( I say this to anyone else who is inquisitive)

6. The oil cooler has three passages. Cooler in, cooler out, and cooler bypass. Even when the oil is hot and fluid, a sizable portion STILL BYPASSES THE COOLER!! Only 50-65% of all the oil is actually cooled!! This gives an overall increase in fluid passage and largely negates those bends....

7. The pump is another product of fluid motion. It does not matter whether it has an outlet cover or not - just look at the internals. You have so many mm's of pump gear and ONLY so many mm's of outlet size. The natural outlet size is intangible because the case hole is nowhere near the same size -

BUT-

The outlet hole on a full flow cover IS the same size as that of the main galley.... (IMG:style_emoticons/default/idea.gif)

If you have a haynes, open it up -the oil diagram is there, - it is all there in black and white (again, for those inquisitve)
