Oil Cooler for 2366? Options

[VWTortuga336]

What would be my best solution for adding an oil cooler on the 2366 build I am starting? I've read about coolers that mount under the rear of the car and are cooled with a fan. Is this the right direction?

[Dave_Darling]

Probably not.

The amount of oil cooling an engine needs can vary quite a bit, depending on a ton and a half of things. So just seeing "2366" won't tell us how much cooling the engine needs.

But chances are that it will need a pretty decent amount, and under the trunk floor is far from the best location for the cooler. You ideally want the cooler to get a good supply of cool, clean, high-pressure air. Under the trunk floor it will get an indifferent supply of air warmed up by the engine and especially the exhaust. The fan helps, but only so much.

That setup is a compromise, and is generally used when there are other constraints that need to be satisfied. In my case, for instance, I did not want to run hoses forward in the car, nor cut holes for the air ducting. Mine is almost adequate for my particular 2.0 engine.

If I had to pick a setup for your car, I would say that you need to run a front-mounted cooler. It doesn't have to be a 914-6GT style, but that is a very well known setup. You need to duct air to the cooler, and duct the warmed-up air out from the cooler. You will lose some front trunk space to do it, though.

I have hi-comp 96mm P&C "2056".
914Dave & I came up with this setup to keep
my oil temps healthy. Originally just a Mocal cooler sitting next
to trans. When I upgraded to the "2056" we added the electric fan and shroud/box. Never really above 220F on a hot run,
on a 90F day. Stays between 180-210F per the vdo gauge.
This works for my set up. Not knowing your set. I imagine the
heat units will be greater. Maybe trombone or other 911 style setup toward front
for more volume of cooling air. Good luck.

Cheers, Dion

I would imagine that it will need a bow mounted oil cooler - thats a lot of displacement for a T4.

Most of us running stern mounts are cooling 2L engines that don't need a lot of extra cooling to begin with.

Sorry about that, I should have told you more to begin with. Here's what I'm building:

Stock 71mm crank
Stock 2.0L connecting rods
Stock 2.0L 3 bolt heads with new 36/42 valves
Forged JE 103mm pistons
Cast iron 103mm cylinders
SCAT C35 cam - .495" lift, 285 duration (matching lifters)
Weber 44 IDFs
Stock flywheel
Bursch exhaust
2.0 SS heat exchangers

[Dave_Darling]

Put the cooler up front, and hope. The cast-iron 103s aren't known for running cool.

Are you planning on running the stock fan and cooling for the engine, or is that planned to be upgraded with a DTM, or a Tangerine horizontal system?

Big engines require big cooling.

And by "not known for running cool," he means they are known for running hot. (IMG:style_emoticons/default/blink.gif)

Yes, I'm planning on running the stock cooling fan and tins.

When you say "up front" at what point do people just mount between bumper and chassis and at what point is the cooler installed in the front trunk with ducting?

A design that worked for almost 30 years.

Put the cooler up front and don't fear the cast iron cylinders.

I have the same question. If someone could give me some more direction on this setup, I'd appreciate it.

30 years, 1/4 mile at a time...

Have you owned one?
I have and still do.
Built a few more that are still out there running around.
You are spreading another myth, and it's sad coming from you.

Bursch exhaust

There's the bottleneck right there.

I've been considering ditching the HE's. What would be a good alternative?

[JmuRiz]

Give Racer Chris a call and he'll come up with a setup to help your big 4 exhale better...can even have heat boxes put on.

My 2316 has the Tangerine Evo .... That along with the big ITB's put out 165hp at the wheels....and the sound will put a smile on your face that you can't wipe off with a handful of hundred dollar bills!

[Dave_Darling]

So you have an engine running 103mm cast-iron cylinders for the past 30 years? For 100K miles or more? Impressive if so.

The "1/4 mile at a time" was an exaggeration, for effect.

The fact remains that the QC on the 103s and 105s that we could get for so long was pretty miserable. They also have smaller fins to still fit under stock tins, which doesn't help with heat.

Do they all have heat issues? Probably not. But I'd bet that the ones that don't either live in a nice cool climate, or had a whole lot of attention paid to the details of the configuration and setup. Details that, sad to say, most people don't seem to bother with.

So, I will retate an opinion--if you are running a 103x71 motor, put a big cooler on it, and hope. Unless you've sunk serious bucks into it, you have pretty strong odds of it running hot and living a short life.
