size diff. between HAMP filter and RYCO Filter.

Does anyone know. Thanks

they are different. Are you after specific measurements?

not really. im looking for a smaller filter since i got a fat oil pressure sender. i cant use normal size filters anymore.

Hamp are the oem ones right? They are definitely smaller since when I switched to them last oil change I couldnt' use my freakin oil filter wrench on it. Wouldn't go small enough.

do you mean under the same product code? I dun think so....

You can use the one for the DC5 Integra,

it is much smaller, but has the same thread and o-ring size as normal Honda one..

i am using one now, as i believe that it improves oil pressure (as it is smaller)

thanks

he's talkin about oil filter not pod filters

ar k lol soZ

so using a smaller oil filter increases the oil pressure somwhat?
and the 'con' is that it doesnt filter as good as a larger filter?

change the link on the oil pressure sender and relocate it.

no, no con... (if you change filters every 10'000km)

just higher oil pressure...

so whats the gain of higher oil pressure ??

how do these compare to standard honda ones ?

so whats the gains of using the hamp filter over the honda one ?

this does not concur with my personal experience...

but this is with a oil cooler and oil filter relocation kit.

apparently (and in my own experience) smaller filters increase oil pressure and oil pressure consistency...

eh?
all honda filters are the same bar the nsx and some other v6 hondas.

prelude
teg
civics
s2k
crv
euro
accords.
practically use all the same oil filters.

The stock oil pump pressure relief valve keeps the oil pump from producing excess oil pressure no matter what volume the pump is pumping into and it's set at the factory oil filter volume has no effect on the valve.

The pressure relief valve inside the filter they are discussing in your links is just internally to the filter and the valve opens when the filter is TOO CLOGGED to continue operating safely inside it's burst rating it is NOT controlling engine oil pressure it is just determining which path the oil takes inside the filter, like normal operation with unclogged filter or bypass the filter element when the filter is clogged only.

so why, when i fitted a smaller K20A oil filter to my system, did the oil pressure increase?

so what is the 15400-PLC-004 oil filter?

i went from:

a Ht=75mm Dia=84mm size oil filter:

to a Ht=85mm Dia=69mm size oil filter:

http://image.racepages.com/live/A6000116609OES.JPG

and my oil pressure increased?

was this a coincidence?

if so, why did my oil pressure decrease after i went back to the original sized one?

PLC was the older one.
RTA is the newer one.

both the same, just a diff part number.
same size and all.
PLC is made in jap
RTA is made in USA and jap, depending which batch it is.

so what is the top filter in the two pics i posted above?

the first one, must be a old type honda filter.
the newer ones is like the bottom. small, it's been the small one for at least 4 years now.

could it be internals of the filter , rather than SIZE ? IE one flows better than other type etc

yeah im just wondering what the gains of using the hamp filter would be..

even if it did help oil pressure increase.. wat would that do ??

The CEO of Spoon recommends using a smaller oil filter to increase oil pressure and stop it from fluctuating in the best motoring video about the ITR

i guess having a more constant oil pressure is always better.
lol.

my *problem* was that once i installed the 19 row oil cooler, the oil cooler lines, the oil filter reolocator, my peak oil pressure dropped to 70-75PSI above 3000rpm... wheras it sat on 80-82PSI prior to the installation.

by fitting the newer smalll type of oil filter, i improved it back upto around 79-80PSI peak oil pressure.

well, compared to the "old type honda filter", the "new small type" improves oil pressure.

and FYI - if you buy a oil filter for a pre 2000 Honda at most auto parts stores, you get a Z79A or equiv. from the dude behind the counter, which is the "old type honda filter"...

are HAMP filters smaller than the oem honda filters?

they are smaller than the "old style" honda filters...

http://www.we-todd-did-racing.com/we...ZkMzF5NTQx.jpg

on the right = "old style"
on the left = HAMP filter

well as long as you buy a genuine honda filter, it's the same size.
from the 1980's model til current, most of em will use the same filter.

so i don't understand why they would give you such a big filter when they can just give you the small one.
since it's all the same.

isnt there 2 HAMP styles? the short and stubby one and the tall and thin one?

Resurrect an old thread :)

So seeing as I use a Ryco Z79A, is there smaller filter used on another honda which will fit my B18C?

OEM honda one is smaller

if HAMP is OEM honda filter, like i see people saying, why are other OEM's blue, and differently sized?

filter with less "total filtrate area" would result in less head loss (aka pressure loss, cause some pressure is used to push the oil tru the filter), assuming the smaller filter has less filtrate area. well, that is my understanding from the fluid mechanics class þ..

Actually from my own experience about asking about filters in the past...

quite a few parts places still stock the older "fat" filter types....which they offer for the older "normal" less sporty models and the thinner ones for the more performance orientated models...

I've generally only used the thinner type (you can also get aftermarket oil filters (non honda) jap made, that are the same size which can be used up to 10,000kms (thin type)

oh and the thinner one usually costs more lol

Sorry, had to dig this thread up because I wanted more info. Tinkerbell, is your oil pressure sender located before or after the oil filter?

BTW, hope you passed your fluid mechanics class. :p Larger surface area means less pressure drop. Think of 10 people trying to get through a single door at the same time in a rush. Then compare that with 10 people and double doors.

located at the remote relocation plate, so after i guess?

Because a smaller filter with less surface area should give a higher pressure reading before the filter and a lower pressure reading after the filter, assuming that the flowrate the same and that it is maxing out the smaller filter. Unless, the bypass valve was opening earlier in the smaller filter because of the higher upstream pressure. I'm asking this because I just bought a batch of the HAMP ones, only to find that they were smaller filters.
