Tommy Meyer is a Ford guy and is manufacturing new Ford Cleveland blocks and parts in Minnesota.

He offers this oil filter adapter which, I believe, will screw into a Mopar block and allow the use of a higher flowing oil filter. He reports at least a 10% increase in oil pressure on his customers engines. Not a bad thing.

Take a peek...


Oil filter adapter
 
Will this adapter raise your oil pressure? Maybe/May not.
The purpose to use this adapter is to use the Wix 51268 oil filter.You will see in the documents here, the the 51268 has almost the same flow as the 51515R, and almost the same filtering as the 51515. So really the purpose to choose to use this adapter is you can have the filtering quality and flow ability

*51268 WIX max flow rate 18-20, Filtering micron rating 25 (smaller the better)

*51515 WIX max flow rate 7-9, Filtering micron rating 21 (smaller the better)

*51515R WIX max flow rate 28, Filtering micron rating 61 (smaller the better)


Why would you need it when the 51515 is a Mopar filter?
 
I wonder what the K&N HP2004 fitter compares to the Wix?

The larger the micro the more it will flow, it lets larger partials thru.
 
Just like the 51515 WIX and 51515R WIX, K&N has 2 separate part numbers usually recommended for street and race use (less restriction) - "R". Also, does the smaller end of the adapter cause any restriction that would minimize the benefit of a better flowing filter. But a smaller micron rating is usually recommended for the street and higher flow for racing.
 
i cant imagene you couldnt find one that flows at the higher rate and has the right pitch

i dont think i trust him much, with his "maybe, maybe not" statement
doesnt sound very knowledgeable

It is also a Ford filter.

I was going to order one of these adapters when first available but I decided I didn't really need the better filtration on my race motor/engine.

Higher volume is always desirable on an SBM to oil the mains.

The stock block 351c also has similar oiling issues to the mains. Meyer has fixed that on his blocks.

I just threw this out for discussion. Lots of ways to skin a cat.

I avoid the 'R' (race) filters for a reason. That 61 micron converts to .002". What is you rod bearing clearance? .0015-.002"? If .002" then the gap from rod bearing to crank is nominally .001" all around. So you're allowing a substantial number of particles into the system that are twice as large as that nominal clearance.....ow!
 
That's Timothy Meyer. He's a smart guy, but I don't agree with his theory here. Any filter (air, oil , fuel, "whatever") that allows "more flow" also allows more of what you're trying to filter get into the system. Nope. Not for me. If you're looking for an increase in oil pressure by using a different filter, you got something "WRONG".

a small increase in particle size 21 > 25 microns but twice the flow
 
so use a longer filter with a fine micron
or use a remote dual filter
I run a dual filter on my boat motor using the LONG GM truck filters
have a water to oil cooler in the adapter
