Thanks. Pictures would be good too.

I'm still hacking away at it. The holes I made in the front are pretty small, I may have to open them up but I wanted to try it out first. I have more pics at http://www.marinerc.net/914/front_mounted_oil_coolers.htm

Thanks for the front view.

Follow-up on the drive home after work after 6pm in traffic. By the time got to my destination I was back at the 260 mark

Did it used to run this hot? Or is it just after you got it tuned that it runs hotter? The state of tune of the engine can have a large impact on the oil temps.

the timing a bit too.

It used to run pretty consistently at 220 or lower. What would have happened during the tune-up to change the temp readings?

Well since my car will not hold an idle setting, most likely because the MFI throttle bodies need rebuilding, I can't control the timing. It is supposed to be set at 1000 RPM, but sometimes it idles higher and sometimes lower.

Timing. The Cap'n

So are you now telling me that if I get my throttle bodies rebuilt and the timing to stay at a fixed idle my cooling problems will be solved?

your oil temps will drop *SOME* if timed right


what is enough drop in temp? only you can decide

Gwen,

timing affects a lot more than idle.
I really don't know MFI at all.. (wish I did)

but I'd bet that MFI has capacity to adjust idle independent of timing.
perhaps your throttle shafts prevent you from getting a steady idle...

but you should still be able to retard your timing and then readjust your idle independently.

It has been advised that my car's oil temp should be between 180-220.

Gwen, why not put the spare in the rear trunk?

I've have this set-up on my 3.0. The car was my daily driver. Never runs hot.
Fog light/horn grills mount over the coolers. Plumbing's not purdy...but it works. Vents out through the wheel wells.

Then the targa top won't fit in the rear trunk.

interesting...what's the inside of the front trunk look like? And where to the lines run to get to the engine? Where did your horns go?

All you need for the spare is that it's the right height, not width. Just use a stock steel 911 wheel & tire, and your top will still fit.

Horns??? One is bolted to the interior of the trunk, the other currently is not (note that the front panel of this car has been replaced with a '73+). Lines run under the right rocker panel (jack piont needed slight modification).

Well I have good news and bad news...

The bad news is that I can't go to this year's RRC party in the desert

The good news is that this gives me more time to properly sort out this oil cooler installation project

BTW-I'm back to wanting to do the fog light design.

McMark? Up for the challenge? I liked your offer. Can I trust your abilities?

We will miss you Gwen,
but it will be interesting to see the project.

brant

I'm disappointed about missing RRC '06 too, but family matters take priority.

Gwen,

If you can get Mark to take on the project, I strongly suggest you do so. You will be happy with his work.

You up for the fog light cooling challenge McMark?

If so, what's your schedule like?

hooray innovation!

My schedule is crazy. I'll have to PM you Gwen. I need to look at my calendar. Maybe Septemberish. I'll pm you and give you a real date.

OK. Standing by...

Terrance,

where are you going to exit the air?
any duct work planned?

brant

It's going straight out through the front of the wheel well. Probably use thin gauge aluminum for that. I used some foam tape to form a good tight seal between the cooler and the front of the car.

Gwen, don't know if you saw my latest development.

I was out in the hills today busting it up and the oil temps stayed below 200°
It was near 100° in Napa today...hideous.

Will the report from Sear tomorrow night mean anything to you?
My goal is 220° or lower. Forecast in Sonoma is near 100° Arrrghh!!


KT

Ya, it's scorching in the south bay too. GTEENER is in her shady garage....

Did Mark help you with your oil cooler setup?

He has seen it. I'm the wrench

I was installing my Mocal cooler today in the front and I was wondering about water drainage. Since the cooler is inside the vehicle instead of outside, water will get in from washing and rain. The only thing I can think of is put some water in there and drill holes in the low spots.....What did you guys do?

Has anyone mounted a cooler where the fresh air vent is? It is a good low pressure area.

High pressure area, but it's still a decent location. I don't know anyone who's done it, but for a smaller engine, its a possibility. the issue becomes getting rid of the hot air.

I've seen it twice.

good it you plan on gutting the car.. (race-ish)
a guy in my vintage club runs his cooler there on a stock 1.7/4 and it is adequate for that motor.


of course it raises weight and the center of gravity a bit.
for a serious race car, do you want that weight going that high?


brant

McMark's right. The base of the windscreen is a high-pressure area. The air has to be forced up and over the car, and pressure builds there. This is why you see air intakes for ventilation systems on most cars.

I've seen one 914 with an oil cooler mounted there, on top of the fresh air box. It was a 3.2 Six conversion, and that smallish cooler seemed to be enough to keep the oil cool. It didn't, however, generate all that much heat into the cabin, which was the other reason cited for mounting it there.

This with a factory 6 oil cooler keeps it plenty cool (tested in AZ heat!). Thermostatic fan kicks it on when necessary. Not my doing, I miss my wipers.

Lee,

I forgot you had your cooler there.
so that is 3of them done that way in colorado!

Lee, why don't you come out the moab RRC06?
it would be great to see you again, and a nice reasonable objective to get the yellow car back on the road!

brant

This is an interesting placement.

Can a cooler be mounted there without losing the wipers?

I'd get a GT valence, un-block the plug-holes and wouldn't need to cut much of the chassis...

Years ago, Wayne Bake used this location in his IMSA car. Very cool. The traditional front location he used to divert air to cool the brakes.

Gwen,

no pictures, but Ed C. in San Antonio(?) TX has an oil cooler behind the fog light grills on each side. It works on his street/auto-x/DE car in HOT Texas contrary to the nay-sayers that "think" it won't work

Having said that, I'm a fan of the GT oil-cooling method, it's proven to work and looks the best..........

As long as you don't want to keep your full-size (205/50 15) spare tire and be able to stash you targa top in the back trunk.

Yeah - I'm not sure this is entirely needed, but I like it enough that I am trying to find a different way to do my wipers (Jeep ?). You're right on not cutting much of the chassis, but I have a big hole in my firewall, and it's not a real 6 anyway, so.....

And Brant, Free time is my whole issue right now, I have become a major workaholic, spend all the rest of the time trying to keep the girlfriend happy (gardening, not cars are her thing)... but I lurk, so there is hope. September is out, though <sorry>

I really don't see how the GT cooler method (or a nice variant of it) and the front mounted tire cannot happily co-exist....just mount the tire on the bulkhead of the front trunk instead of having it lay flat...that size tire should have an envolope size of ~8.5" X 23.2"...maybe it is too tall, don't have a 914 in front of me to measure

dang...
we will miss you.

best of luck
brant

gwen...

just upgrade or get a spacesaver...

i posted the pic of mine on my front bulkhead, aft of the cooler right?

heres mine.

Note, the car has a 3.0, the former owner says he never had heat problems, I've only driven it twice, although on the hottest two days in the history of the Santa Cruz mountains.

It does seem very exposed thought, that worries me.
