first attempt at a real oil cooling circuit (need approval)

[supraguru05]

currently the oil cooling setup in my car is as follows. its a 1989 NA supra. i have a permacool sandwich adapter with 1/2 in outlets going into this cooler

http://store.summitracing.com/partd...924500+4294888847+4294782888+115&autoview=sku


i have no thermostat in. and used non braided hose from permacool and barb fittings.
i am now putting in my turbo motor and am ready to step up and do this right. here is what i have come up with
i was going to run the outlet from my oil filter adapter to this filter mount mount

http://store.summitracing.com/partd...400006+4294851620+4294851462+115&autoview=sku

putting a oil temp sensor in one outlet and sending the other outlet to this thermostat

http://store.summitracing.com/partd...1070&N=700+400006+4294843279+115&autoview=sku

blocking the extra inlet and outlet ports. sending one outlet to the cooler i currently have which is linked above. then taking the outlet of the cooler back to the oil filter adapter on the engine.

i am going to plumb everything in 1/2 in braided which i think is -8 an line.

i need feedback on whether this setup is a good one or if i can put some better parts in here. thanks

You're on the right track

Plumb it like this...filter adapter like this one (you need it in 3/4-16)on the block using a 7M-GE filter stud:
http://store.summitracing.com/partd...=PRM-114&N=700+400006+314600+115&autoview=sku

- "Out" port from above adapter to the "in" port on filter head...I see you are using a dual head. Suggest a Wix stock size filter and a Trasko by-pass filter:
http://www.trasko-usa.com/

- "Out" port from filter head to "in" port on thermostat...the link did not specify the temp...you want a 180 deg stat.
The thermostat works by by-passing oil through the middle "stud" until it closes off when the specified temp is reached.then oil is routed to the cooler. You want the filter head "out" line and return line to the block filter adapter "in" port on one side of the thermostat...both cooler lines on the other (same) side of the thermostat. If you think about it, it makes sense...oil flows to the filter head, to the thermostat and back to the block until it gets hot. Thermostat opens up to the cooler and follows the same line back to the block.

- Your cooler choice is excellent

- AN-8 lines should be fine.

- The filter head you linked to is dual sided...you will only need one side for the above set-up. Get a 1/2" NTP plug at the hardware store, drill/tap the center for your temp sender, and use on the side of the filter head with no line. This will give you pre-cooler temps. If you want post-cooler temps, you will need to install a "T" fitting on the line from the thermostat to the block.

id go with regular rubber lines, braided is total over kill and expensive. unless your running 800psi of oil pressure just use regular rubber.

 

[supraguru05]

thanks for the advice. i copied the oil cooler choice a year ago from a mk4 supra guy so i figured since he had tons of money it must be nice. is rubber hose really safe to use on a track car. ivve been told no way by multiple people but it would be so much easier to use.

o and sorry about messing up the plumbing of the oil return line. i knew that the cooler is routed back to the thermostat i just was not thinking and i tend to type in half sentences that make no sense.

 

[gixxer750]

I used regular rubber hose my first time and had leaks.... Braided hoses are the way to go IMHO...

 

[TurboStreetCar]

well really the only added benifit besides pressure capability is that its much more resistant to abraising because of the outer layer of SS. Personally, i wouldnt use braided stainless when theres cheaper alternatives that are much easier to work with.

Braided line is used for nitrous lines that can exceed 1000psi, oil pressure shouldnt really be much above 100psi for any practacle purpose, theres rubber lines that will handel that with ease, Also you wont have to spend 15-30 bucks each for fittings. just use NPT (or whatever the connector on the oil cooler, filter adaptor, and filter mount) to hosebarb fittings that can be found at any decent hardware/plumbing store and use hose clamps. cheap, effective and easy.

A matched barb an hose shouldnt leak, They fit REALLY tight.

Well, it has to be oil specific hose, not just regular hose. But chunks is right, you aren't stopping the car, it is the oil cooler.

parker makes some real nice high pressure oil hoses. really tough stuff and wont seep thru. plus they are local.

b&m coolers are nice, near indestructable unlike the fin type.

 

[jdub]

This is also a good option for hose that's cheaper than stainless.

You will still have to use AN-NPT fittings on the cooler, etc.

Pirtex Rubber here (much the same quality as Parker) 0 leaks.

 

[supraguru05]

when i first plumbed it a couple years ago i used some hose i got from perma cool and have no leaks on barb fittings. im thinking of using push lock hose from jegs heres a link

looks like easy to use and relativly cheap.

i think this would work with the barb fittings from local hardware stores.

Great link John, I'm saving that site for future reference .

It will, but I would clamp it...if you take a close look at the fittings for this hose, the barbs are more pronounced. The hose at Jegs is basically a copy of the Aeroquip stuff.

Yep...Baker Precision is great and prices aren't too bad either. They have a lot of metric fittings too, but you might have to give them a call. They have more than is listed on the website.

 

[starscream5000]

Do the hoses come with metal ends on them when you order your footage? It says the hose ends are AL, so I guess I'll have to make sure how long each section needs to be before I order?

 

[jdub]

If you order from Baker, it's by the foot for hose. Just measure what you need and add a little length for those bends you forgot. Cut to length when doing the install with a razor knife.

You gotta buy the fittings, scroll down below the hose...the barbed end is for the hose itself, the AN end screws on to the AN-NPT fitting (gotta buy these too) you have attached to your filter head, sandwich adapter, etc. These function exactly the same as stainless hose...you simply screw the hose to the AN fitting. Makes taking the hose off a breeze too

 

[starscream5000]

Yeah I seen the fittings, the statement on the hose description is what threw me off.

 

[jdub]

I see what you mean...plus the pic shows a hose with a fitting attached :icon_conf

This hose is really easy...cut to length, push on the fitting, screw on. That's it!

I had parker hoses Dave and they sucked....they didn't last 6 months before leaking from deterioration. Get Aeroquip hoses they are better made and don't wear or leak. I used aeroquip hoses and socletless push lock barbed fittings with no leaks. I don't reccomend any of those cheap ass summit cast aluminum adapters, and filter mounts. I had them they suck....they easily crack and if you try to tighten them to seal they will crack. I got billet aluminum adapter mount from earls, and a dual aluminum billet filter mount from Amms oil. Summit has a dual billet filter mount for 80.00. The billet pieces cost more but they don't crack or leak! Going cheap will kill you in the end at some point. I used the summit aluminum earls thermostat as well, with the B&M 70266 oil cooler!.
Dont cheap out here. Use the mobile 1 oil filters for they work really well also.

 

[starscream5000]

There are better oil filters out there that are cheaper than the Mobile 1.

Do tell....the mobile 1's were the only ones to take 120+ psi cold start ups without bursting.
