Front Mount Oil Cooler

[BSKI]

Guys I have an 82 930 with the 28 brass tube OEM front fender oil cooler. Looking to upgrade. I am thinking the B&B or the elephant racing wide mouth cooler. Any opinions/pics/suggestions?

I have the B&B and no problems so far , It would be nice to have a fan to cool it at the track ,

I have a 1980 930 that I intend to track in hot weather. So I'm going with the stock fender cooler plus the front mounted cooler tucked behind the RSR bumper. Figure two should do it but it gets hot in California so I may need a fan, too. Had oil heat issues before. Will update once it's out of the shop.

Seems to me that upgrading your brass cooler to the er widemouth would be fairly costly for very little increase in performance. You might be better off adding a fan to your brass cooler and finding an additional cooler to the other side or front. I had a trombone type 'cooler' (if you even won't to call it that) that I replaced with the er widemouth and fan, I'm very happy with the results.

I think the ER stuff is top notch above all others. For the fender mounted cooler getting air to it is the major issue. The fan helps but is not the end all answer.
If you intend to track it, which you did not mention, then a front mount cooler is the only way to do it. You wont get enuff air flow inside the fenders to the coolers there at a track event with the 930 engine. Even with another mounted inside the drivers side fender.
The front mount cooler in tandem with the ER fender mounted unit that replaced my stock trombone cooler was what I did after having oil temp issues during the summer track events at Watkins glen and Mid ohio in my 79 930. It still gets hot near the end of a 25 minute session for me with oil temps about 220-230 degrees and I am making about 420-450hp in my 3.4 liter engine I have to guess.

What's your reason for upgrading? Are your temps getting too high, are you looking to lose weight, or are you wanting the aesthetics of a front cooler?

If you are getting high temps there are some things you can try before the time/$/hassle of an "upgrade" which may or may not solve your issue.

ER stuff is good. BAT makes a kit.

I've got the ER fender mount (ie stock replacement) cooler with a fan, and my temps are much lower both on the track and in summer traffic. I've also got the scoop thingy from our host which replaces the front right marker light - haven't installed it yet but I suspect that I will see even lower temps on the track once I start using it.

HAPPY NEW YEAR-GUYS


Poor mans way-but effective

Personally I installed a 2nd generation mazda rx7 oil cooler..Approx 25-27inch.long 2-1/2thick, 4-6-height.(junk yard-$35-$100).Search-Some guys on the board it. And I tried it out. Brought the lines-bradied & 12an fittings on amazon-cheapest place...Brought the 2 -30mm straight fitings & 2-12an fittings/weld on the oil cooler at BAT-INC-Florida-
I was under $200 after I was done.(good if your handy)...Worth it...INMOP.

Thanks for the replies. I have tracked my 930 but for the most part it is for blowing off steam after work. I've owned the car for 4-5 years now and have always questioned the running temp mid summer or after running it hard. This past fall I did remove the front running light to see if the increased airflow would make much of a difference. Obviously it did help. My only problem is I don't like the look of the scoop thingy and do want to keep the light in for estetics. I do like to do an upgrade or two each off season and figured the OC with a fan would be a good investment. I have thought about the front mount OC but would be getting into a new front vallance which may or may not happen at some point.
By no means am I rolling in cash but when it comes to my ride I don't mind spending the dough to do it right. Just want to do it right the first time.

Depending on what you run for a valance you can also box in the FMOC. I know when I was working in NASCAR we would build a box from the bumper cover to the radiator and it would drop coolant temps a ton. Almost like "ram-air" for the cooling system. I am planning to do this on my build. Anyways, that's my $.02 for what it's worth.

My opinion: Go big or go home. When it comes to oil cooling the engine there is not enough you can do to help out the turbo 3.3.
I decided that going to a front mounted cooler is the best option as the fender mounted units are not even close in heat rejection. The key to any radiator style cooler is getting airflow over the cooling fins, and secondly lots of oil flow thru the cores. The front mount is like ram air when moving at any appreciable speed and the fender mount style are hidden behind the bumper and headlight bucket. Dont choke down the oil line diameter from the fender mounted unit to the front cooler either. ER units maintain a 30mm fitting on their coolers.
If you do any sort of hard driving for any amount of time the oil temps on the turbo are going to increase quickley. If tracking the car this is quickley apparent.
Get the largest front mount cooler to fill the entire opening in the lower valence, then provide space behind the cooler for the heated air to escape. Might as well get the biggest oil cooler you can fit up front if getting any at all. If the oil gets too cold the stock fender mounted thermostat will limit flow to the units up front anyhow.

Nice set up! Can you please post more pics of the underside mounting of the front oil cooler? I need to install my front mount oil cooler and upgrade my fender cooler.

Thanks,

I believe we all have gone through the same issue, IF you track your 930... There is ONE trusty solution = front valance cooler.

I was running 250* at the track, tried all of the above (i.e. timing, scoop, fan, no headlight, second fender cooler, no turn light...) with little improvement. Got an ER Setrab cooler, installed it in series with the fender one without any tub mods - there is 2" gap between the cooler and the tub, modified the OEM valance to accomodate it keeping the OEM rubber lip; since then, I don't see any temps higher than 210~220* at the track.

Being in TX I think I am going to run a front and two sides with fans on separate manual switches for heavy traffic.
