I want to install front oil cooler, for a high compression 2.8.
What the best on the market?

Thanks,

Retro

I like Fluidyne. Dunno if they're the "best", but they're a good lookin' unit and customer service is top notch. You can deal with them direct.....Goggle ought to find them.

Fluidyne all the way. The thermal characteristics of the Fluidyne are leaps and bounds above the sandwhich style Mocal/Earls/Setrab. Bottom line: they are more efficient.



B

Yeah.....what he said...all them thermalthingys.

The radiator style just works. All the factory Porsches use a radiator style oil cooler (993's came stock with one mounted in the right front fender) Even our stock 4cyl oil coolers are radiator style.



B

how much for one?

i have the "while i'm in there" itch ...
Andy

What could I expect to pay for a nice set-up?

KT

Thanks Brad & JP.
Which model do you suggest?
Do you still agree to vent under the car, which seems wrong to me.
I would think out the hood would be best?

oh oh, you shouldn't have said that ....

oh, oh, why?
Now what have I started?

Retro

You'll see...

Out the hood works best. It tends to dump heat into the passenger compartment when the roof is off the car. Track car.. exit out the hood. Street car.. exit beneath the car.

B

brad hates the "through the hood" idea. i have argued with him on several occasions and he has nothing good to say about it.

if i recall right, his main argument was "with the roof off, you'll be getting all this extra hot air inside" ...

i guess guys from texas don't need hot air?
Andy

Choose from these. I have installed/ran just about everything on this page:

B

so, b. meister, seriously, what's it gonna cost me?

- good front cooler, braided lines, thermostat and all?

i have the sandwich adapter for the oil-filter pickup ...
how much scrilla?
Andy

I just dont see a need to vent any of "our" cars through the hood. The inlet requirements and outlet requirements are VERY small. You dont need a big HONKIN hole in the hood.



B

Figure 1700$ to be safe. That should be everything including a GT shroud/fittings/-12 braided line.



B

I use the DB-30416-12 (the -12 is AN IIRC)....bout 300 bucks, but that was a couple-3 years ago.

Venting? None of the above...kinda.....hay, it works.

hmmm, that's not too bad ...

if i use the pass. long for the lines, i'll still have heat on the drivers side.
plus, i'm going to cut up a perfectly fine hood (of course!), no need for a GT shroud.

alright, can you order the parts on monday?
cooler, good thermostat, ~12 braided lines + fittings.
anything else?

Andy

Here is a picture of a 914 I had with hood vent. I never noticed heat. I assumed through the hood would detach air flow, retarding lift, creating down force?


Retro

The nose naturally creates downforce with any kind of splitter on a lower airdam.

I can order the parts Andy.

I suggest the way JP did it. Two vent holes above the steering rack. The air escapes out the fenderwells..



B

Off the top of my haid.
Cooler 300-Fluidyne
thermo 210-Troutman....I paid less but you won't
lines & fittings 285ish.......there was some dickin' around involved here gettin' the right fittings. I have 8 feet of -12 & 2-3 straight fittings left over if anyone wants for cheep.

I thought I remembered reading some where that the exit was to 2 - 3x larger than entry?
Not so?

It's amazing how much bullsh....ah....info we can generate in a short period of time, eh?

Brad: 3 holes, damnit....wouldn't wanna short the venting

Summit Racin' for lines & fittings.

Somewhere in this world there is a formula for calculating the exit needed for a given entrance. Obviously the air expands as it exits the cooler...so yes the exit should be larger, but how much is the question. 2-3 times is a little much.


B

Yeah, I heared that also.....but....
A nice high pressure intake + low pressure outlet(WAG). I was prepared to cut more holes as necessary...it wern't. 100C is the peak oil temp I have seen. 90C at a track day.

You've seen me flog the car......20 AX passes in about 2 hours that day....and it was 80ish.

here you go, from my favorite science website ...

Andy

I agree. Stick with small openings and small exits. Right this minute I have HALF our Fluidyne cooler blocked off to get the car to up to temp during a 20 minute race (8500RPM injected 3.2) NO engine mounted oil cooler.


B

couldn't you run a thermostat near the engine?

Anyone familiar with the P-51.....besides Andy's granpa

The vent for the radiator was about the same size as the inlet.
I read that it supplied jet thrust to the airframe.....a design featurette. Them's were some fart smellers.....smart fellers....whatever. If true, it has no application in this discussion......humph.
