For everybody out there running a GT style cooler, would you mind posting a few photos of your cooling setup and fans?

Currently re-routing my system to use a SETRAB type cooler (example here: https://patrickmotorsports.com/collections/oil-system/products/oil-901-207-gt-foc-pmp) however I don't see any reference to fans, and it doesn't seem as though it's an option to purchase.

Also, appreciate any 'pointers' in the right direction when it comes to vendors that might have similar products / solutions. Thanks in advance for your help!

Gts where fast = air flow

Posted by: Retroracer Jul 18 2020, 05:41 PM

Hi - so for my 2.2 six based GT tribute, I used a Behr oil cooler from an old 300D Mercedes. Sourced from a pick-n-pull. It fits nicely in the space under the shroud, you just have to deal with the metric threads and the placement of the inlet/outlet (one each end; its a single pass, unike the original GT ones which were double pass). I recall it cost me more to have it flushed & pressure tested as it did to buy from the yard....!

So like the GT, no fans used. I run a thermostat near the oil tank and 10AN lines running up and down the rocker panels. In CA weather I rarely see oil temp above 80degC (bear in mind I also have the forced air cooler on the engine too).

Hope this helps? Photos below show build progress; I made a up a long bracket to support it which ends being part of the front end reinforcment. Also, I didn't do the full floor cut out - just two openings near the back of the shroud to vent the hot air.

- Tony

20 row Setrab with fan pack and thermostat switch.
Air comes in through the stock holes in the front body panel and exits through the body plugs.

I don't run any fans on mine, the only time i've ever seen oil temp get up to 210-ish was when i got stuck in stop & go traffic in Salt Lake City with 100+ ambient temp.

Posted by: Steve Jul 18 2020, 06:45 PM

Same with my 3.2. When stuck in traffic it would get hot. I installed an in-line -12 fan thermostat from summit racing.

Patrick use to sell the fans that fit perfect on his setrab cooler. I bought the same ones from Amazon. I have the part number some where. I installed a relay with the thermostat. Never have to worry about it over heating. Like a modern car the fan comes on and stays on until it cools down.
He used to sell the fans separately

They sell a pusher and a puller fan. So depends on where you mount them . Spal 30103013 5.2" Paddle Blade Pusher Fan https://www.amazon.com/dp/B009OBP182/ref=cm_sw_r_cp_api_i_uU5eFbFP0DH9Z

I think using mb911’s oil lines also help dissipate heat along their length instead of the braided hoses. My conversion just used a Turbotrol cooler in front to control temps with AN-12 lines with good results.

Depends where you live and time of year. if your six is bigger than a 2.7 and it’s over a 100 degrees outside and your stuck in traffic with no air flow, it will over heat no what setup you have. In so cal it can get up to 110 in the summer. AZ and Vegas is worse.

Posted by: mepstein Jul 18 2020, 08:29 PM

That's why I decided on a fan pack. It's my only cooler. I'm using a oil cooler bypass plate on the engine.

Posted by: RiqueMar Jul 19 2020, 08:41 PM

Thanks everyone for the recommendations! I should have specified my current setup; 3.6-964 engine, no on-engine cooler, braided 12AN lines with a thermostat upfront. When complete, the oil will travel up the passenger-side, and meet the thermostat before either cycling back or going through the cooler (inlet and outlet on the same side). As I'm in Southern California and quite often subject to very heavy traffic, I feel I absolutely need a fan setup.

Currently looking at either having the fan on the floor pulling air in and then out, or directly on the cooler itself (preferred). As it goes, at the beginning of this processI didn't fully understand all the options associated with the fans attached to the cooler and didn't know the plastic rod mounts were an option. I assumed you had to fabricate a bracket, so grateful for this help and understanding from you all.

From what I see on the PMS site the general dimensions of the coolers are 17.75 x 4.25 x 1.90. Calling a few vendors tomorrow (PMS, CSF, etc.), and will update here and my project thread for the community.

No fans on a 3.2 six. My temperatures used to be dramatically high on the gauge till I replaced the sender with the proper one for the guage...

Curious if you are running a Steve Wong Chip? Mine seems to run a little hotter with the chip, but it's worth it. Drive-ability is night and day better. Much smoother response.
Mine is also a high compression Euro 3.2 motor, which probably also makes it run hotter.

Posted by: Steve Jul 20 2020, 08:54 AM

I started an AC project section in my blog. You can see my cooler, fans, thermostat and condenser. http://www.914world.com/bbs2/index.php?automodule=blog&req=showblog&blogid=259&st=

Hey Steve! Not sure if you remember, but we met on that 914 run back in June, when we were chatting from some time at that mountain cafe. Just wanted to say thanks to you and everyone on this thread for all the photos.

Posted by: eric9144 Jul 20 2020, 01:58 PM

PMS did fans on the floor section for mine, I only turn them if it gets too hot with little air flow, i.e. sitting in traffic or really pushing hard when it's hot outside. I have a manual toggle switch to turn them on, normally I don't need them at all.

Posted by: GregAmy Jul 20 2020, 03:19 PM

Holy shit that's a gorgeous underside you have there.

Posted by: RiqueMar Jul 20 2020, 05:30 PM

Having seen it in person, Erics car is a 'case study' for perfection.

Called around this afternoon, most vendors I talked to couldn't quite comment on exact fitment, and so I eventually went with the PMS Setrab unit. Happy to get that checked off, and very grateful to the help of all here on the site.

Posted by: ConeDodger Jul 20 2020, 07:54 PM

Steve,
No chip for me yet. Steve wants to burn a custom one on a dyno so we wait until this shitstorm ends and I’ll bring it over the hill to the Bay Area.

where can I source a shroud for front oil cooler? the PMS one looks nice, but pricey.

Posted by: Steve Jul 21 2020, 11:13 AM

I think PMS gets it from Getty. AIR also used to sell the main cover. Getty sells the bottom piece to.

Your welcome!! I'm looking forward to the next get together. Otherwise you can find me at Cars & Coffee every Saturday morning at 7am at Crystal Cove. Right behind Javiers.

Posted by: RiqueMar Jul 21 2020, 12:13 PM

I remember that I sourced mine on eBay a few years back, I believe it was the same guy/company that was producing side-skirts and valences. If my memory serves me right, he/they were out of Murrieta/Temecula, CA

Posted by: RFoulds Jul 21 2020, 12:39 PM

I thought the Crystal Cove C&C was gone? I will be out that way in August, if its still going, Love to attend.

NOS RX7 oil cooler with widened GT shroud to fit cooler

Officially it's gone and they don't advertise. So far we haven't got kicked out.

Posted by: RiqueMar Jul 21 2020, 03:05 PM

@http://www.914world.com/bbs2/index.php?showuser=262 - Curious, how much did you have to 'widen' the shroud?

Posted by: gereed75 Jul 21 2020, 03:19 PM

Enrique, Not sure whether you have seen it or care to go this way, but in my opinion the very best front cooler shroud treatment is the one used by Eric Shea PMB on the car in this thread

http://www.914world.com/bbs2/index.php?showtopic=345715&hl=

It has been seen in some other cars also. Not sure if it incorporates fans but it could easily accommodate two pull fans in each side of the split plenum. Not original GT looking but very cool.

Posted by: mepstein Jul 21 2020, 03:47 PM

Yes, Kelly's car. I believe it was a McMark design. Rory did a similar one in his white GT car. Lots more work than the store bought shroud but very cool. I'd like to convince Ben to make me one in aluminum

Posted by: rktmn247 Jul 21 2020, 07:56 PM

I second that idea!

Posted by: gereed75 Jul 22 2020, 06:42 AM

Actually making it out of aluminum is not a bad idea. A top, bottom and the sides.

Of course it always seems easy in my brain but is invariably two or three times harder and more time consuming to execute in reality!

Posted by: rgalla9146 Jul 22 2020, 08:29 AM

If I may.... as Mark sayes, more work.... but for me it's personal satisfaction.
Rory

^^ That approach is great because it leaves you with a Frunk that's actually "usable"

Between the ducting and the Petersen oil tank, I can't realistically put anything in mine



@http://www.914world.com/bbs2/index.php?showuser=9478 aren't you still using the Petersen "keg" also?

Posted by: rgalla9146 Jul 22 2020, 08:56 AM

You've still got a rear trunk right ? man that's beautiful

Posted by: Marv's3.6six Jul 22 2020, 09:28 AM

Here is my system which is a Patrick Motorsports Setrab unit on a modded 993 3.6. I ran mine for a couple years without fans BUT I got caught once on a backed up freeway and the temps went thru the roof. I added 4 puller fans with a tstat switch. The system configuration, install, fans, and electric circuit were all my design. This system has been a life saver.

Yes

Posted by: RFoulds Jul 22 2020, 10:24 AM

I like the shroud that vents out the side, but mine is for a vintage racer, and any ducting that cools the brakes is not allowed.
I have to stick with the GT style for now

Posted by: mepstein Jul 22 2020, 10:41 AM

It would be very doable for Ben to make these. get aluminum cut with water jet, weld up pretty but it would take a group of committed people. I'm guessing it would be a similar cost to the aluminum oil tanks and it would be based around a chosen oil cooler. Other coolers might fit but we would have to pick one (Ben has a great one already picked out).
I can get a quote from Ben and run the group buy if there is interest but it's not worth it if your not ready to pay $750 for one. It may be more, it may be less but $750 is a reasonable number to get the conversation started.

I also thought stainless steel would be pretty cool.

Posted by: RFoulds Jul 22 2020, 10:55 AM

Getty FG one is $350. the carbon fiber is $550. AIR FG one is $175. $750 is pretty steep premium.

Posted by: mepstein Jul 22 2020, 11:35 AM

Yes. It would be styled like Kelly’s orange car. Air ducted around the spare and out the side. Completely different than the traditional GT style. I’ve also talked to Ben about a more traditional GT style but in aluminum or SS. He made one for his car in aluminum and even if we don’t do a group buy, I’ll have him make me one. I’m guessing $500 +\- There are already plenty of companies that do cheaper glass. I want a premium product in steel or aluminum.

Posted by: RiqueMar Jul 23 2020, 10:36 AM

Thanks for the continued references everyone. PMS Setrab unit arrived yesterday and it's a 'perfect' fit inside the should. Now, I'm eager to see how I will need to cut and modify the fiberglass to accommodate the inlet/outlet fittings. Not sure if I should create a small 'box' on the side, or notch it so that it slides on-and-off.

For those interested in the Setrab unit, a few basic dimensions for you regarding sizing....

Overall length: 21-7/8" (22" with included fittings)
Overall height: 4-5/8"
Cooler width: 1-7/8" (3-3/8" with the brackets)

For those of you that have a similar solution, this thread would be very helpful to see how the hoses enter / exit the shroud and any suggestions on fan wiring. I've purchased 2x Spal 4" pullers fans, and the plastic tabs to mount them directly to the cooler; I plan on linking to it in my blog. Looking at you all, @http://www.914world.com/bbs2/index.php?showuser=12876 and @http://www.914world.com/bbs2/index.php?showuser=3165

@http://www.914world.com/bbs2/index.php?showuser=12876 - To your previous question, no only the stock 914/6 oil tank for me. The engine setup in the previous car had a similar setup to yours with a large tank in front and 2x breathers, but that was specifically for the track.
