Has anybody ran these filters on a street car, and are they any good?

I run this filter on my street/strip car and have no issues. But I only drive about 3-400 miles a year on the street and change my oil twice a year. The filter is recommended by Hughes Engines.

Thanks. I knew they sold them, wasnt sure if you could run it on a street car.

Yes, and with no problems.

I think all the oil filters used on Chevy motors have no internal bypass valves in them like the Ford and Mopar oil filters do I have seen a lot of the oil bypass valves in the adapters on Chevy motors epoxy closed The System One oil filters have a internal bypass built into them that could be epoxy closed

Some good info in this thread at YB (relatively work safe). Not only does he cut open the filters, he contacts the manufacturers for data. Many, but not all, provide specs. (Yes a Jomar is in there)

My moroso oil filter doesn't have a bypass neither and is one of the reasons I buy it. I was going to buy wix racing filters but their tech people are assholes and turned me away from them.

I read that whole yellowbullet thread last night, very interesting. I never thought of the bypass the way they describe it, makes sense.

Am I correct in assuming, if you use a non bypass filter, and it starts plugging up, your oil pressure as shown from the gauge port at the rear, will drop proportionally?

Filter is made by Baldwin--long said to be the best by McCandless
we like them--safe to use in any application--anytime
It filters oil all the time like you would suspect should happen but doesn't
If it is plugging up you are blowing up so....best thing is it does not add to the problem
Jomar and guys that run it are fantastic folks and know what they are talking about you can call them direct for fast shipping and a no BS experience Love those guys!!!!

500 years ago Bill Jenkins recommended the AC832 truck filter, the canister is as big as a garbage can so it's safe without a bypass.
Safe is a relative term. Straight 60 weight and 20 degree oil temperature will blow almost anything off the engine even with a bypass - it's just too much pressure.
It also depends in part on what the capacity of the pump's pressure relief system - some are pretty small.

So if the filter starts plugging up, will you see that as a decrease in idle oil pressure?

When oil pump speed come up with RPMs, would the oil pump bypass then allow normal pressure to oiling system?

Most oil pressure relieve valves/springs are set
at 70 psi so it will by pass at that point.. BUT
flow is what your after.. if the filter plugged up
100%you have ZERO flow
EDIT
The pressure gauge is after the filter

If the gauge is after the filter, a restricted filter would show up as lower gauge pressure?

This will be on a weekend warrior engine, oil will never get dirty, just thinking it through.

I think this is how it would work, just wanted to run it by the discerning minds of Moparts.

Geeezz! I have NEVER had a plugged filter in one of my Mopars street or race
If pressure is dropping you have a problem
Any filter will do and is not any problem
Never seen an engine failure due to a dang filter
Snap out of it!!!!

I have had a pressure drop of 20psi with a
Fram filter.. so did my brother and my buddy..
we dont use Fram filters anymore

I don't fully understand how the pump bypass would behave in a full or partial restriction, with a filter that doesn't have a bypass.

IF the filter starts plugging up the back
pressure increases which puts more pressure
on the pump... the pump by pass opens up BUT
if the filter were totally plugged up the pump
by pass CANT handle the total flow of the pump..
but if your smart the gauge outlet would show
zero pressure and if you put a low pressure
switch on that point to the ignition it will
kill the engine

Thanks for the explanation.

I always thought the pump bypass diverted back into the pan.

I am going to run the Jomars, ordered 3 from Jeg's.

I change the oil once a year, maybe go 2-3000 miles.

Oil pressure gauge should start to show a decrease with less flow.

Thanks again.
