PWR vs OEM

[IcemaN]

just had my oil cooler installed, now using a s2000 or dc5 one. i dont have an oil pressure guage yet so i dont know if i got issues atm:S getting one soon though. i was told im going to lose around half a psi. will find out how its going when i get the guage tho.

[tinkerbell]

you cant even measure 0.5 psi on an automotive gauge...

it is too small to read...

i lost about 5-10psi on my install

[szymonsta]

wtf.. i didnt know there was more than 1 filter we can use.. is it honda? and why do you recommend it? raises oil pressure?

reduces fluctuation in oil pressure in racing conditions.
yes u can get a smaller honda one (its for a different model honda - dc5 or jazz or something?)

And it will just fit directly to a B series engine ?

[Jingers]

yes

[00dc2]

can you get them from honda dealers? what is the part number etc? any links?

[tinkerbell]

part number?

use a K20A2 oil filter

[vtml]

Ah, so just the AUDM DC5R oil filter in that case. I am extremely tempted to go back to Honda and change mine as I just purchased one on saturday so I can service the car this week.

How does PWR compare to koyo, or they are pretty much the same stuff?

[JCE]

Tinkerbell,

Looks the goods, a shame PWR Australia couldn't come to the party with the price.

Have you driven the car with the PWR radiator yet?

I am interested to know whether the car will mantain correct operating temperature during normal street driving (i.e. not run too cold).

no, i have multiple fractures in my right hand after removing my engine a month ago (due to incorrect use of tools )

so my car has no engine in it... plus i have been waiting for my head to get finished... picking it up tonight... then getting my dad to help me fit it, then i have to finish rebuilding my gearbox (waiting on ONE lousy seal from Honda...)

then i will be putting it back in the car...

then i will test the living crap outa it, a full tank of Ultimate and explore the backlands of the central coast in summer...


but JCE - my car ran at 80 degrees all the time anyways, i doubt it will change due to a bigger radiator...

the thermostat controls the temperature, not the radiator...

[JCE]

Yeah,

I just didn't want to say it without evidence as I have no gauges/data to support to my claims.

This is why my spoon thermostat/thermoswitch are now in the bin and not on my car as they made the car run too cold during normal operating conditions.

I think an aftermarket radiator should be the first step taken in order to mantain engine temperatures.
From what I have read oil temperatures only seem to peak when the stock cooling system reaches its maximum cooling efficiency.

Therefore fit a bigger radiator (keep the stock thermostat/thermoswitch) and if oil temps still need controlling fit an oil cooler.

Any thoughts/criticisms on my above assumptions?

[freakygeek]

I think pretty much what James says is correct.

As far as I'm concerned installing a lower-temp thermostat and thermoswitch is only delaying the inevitable. That is, with the stock radiator, regardless of thermostat you will eventually exceed its cooling capacity... regardless of how early the thermostat begins to open.

I believe that we should be looking more to *maintain* the correct operating temperature. This can really only be achieved with a higher capacity radiator, such as what Tinkerbell has purchased. This larger radiator should negate any need for "patch fixes" like lower temperature thermostats and allow him to use the standard thermostat meaning general driving (read: not at track) operating temps should be maintained.

Problems associated with your engine running below correct operating temps :-

Worse fuel economy
Possible premature engine wear
Possible losses in power output


Feel free to comment and correct me if I am wrong... I think there is lots of knowledge out there that needs to be shared!

Very interesting, so upgrading to a low temp thermo stat and switch could have negative effects for road use? I am in the process of getting a thicker radiator combined with low temp stat and switch, but my car is 99% road driven, so it wouldn’t be a good idea to use the Spoon stat and switch?

[JCE]

Take my advice with a grain of salt.

If you are fitting an aftermarket radiator, ditch the thought of spoon/mugen thermostat/thermoswitches.

As the aftermarket radiator is more efficient than the stock one, keep the stock thermoswitch and let it do its job.

When temperatures start to rise, the thermostat will open and the more efficient radiator should do its job of dissipating the heat.

With my stock radiator and spoon thermostat/thermoswitch, the car would not reach operating temps under normal driving and during highway/5th gear driving they would drop to under a 1/4 on the stock temp gauge.
