2 hour oil cooler install, Preparations for WCC Options

[cha914]

Aaron,

I ran my cooler up front using the blue hose and fittings above...and I used the chepo thrucooler oil cooler also.

I think the whole setup from racerpartswholesale was right around 400. That was ~35ft of line plus fittings and adapter and cooler, oh and -10 lines.

The highest temps I have seen are 210 on a 95+ day while floggin the car up a long grade, otherwise it barely gets above 180...so if you have a better fluidyne it will probably work even better.

HTH,

Tony

Well, today was the first day in a week and a half without (forecasted) rain. So I finally drove my car to work this morning - first time since the cooler install. Previous mornings like this I would see oil temps around 210F. This morning I saw nothing over 185F. (IMG:http://www.914world.com/bbs2/html/emoticons/clap.gif)

Currently the fan is wired to run whenever the engine is on but at a very low speed(just enough to circulate a minimum of air through the cooler). I will still need to add a switch to run the fan at high speed when needed.

I'll probably pull the relay that controls the fan for winter operation as I like to see the oil a little warmer than 185.

But I was very pleased with the results. The cooler is doing exactly what I wanted/expected. Of course, a nice hot day will tell the whole story.

Demick,

Congrats!! (IMG:http://www.914world.com/bbs2/html/emoticons/smilie_pokal.gif) (IMG:http://www.914world.com/bbs2/html/emoticons/beer.gif)

Could you list out the parts you obtained for this project as well as approximate cost? I need some additional cooling and don't really want to cut up the front of my tub.
I'm a mechanical dumbass so I'd appreciate anything you have to offer.

[Demick]

Here is what I used:

Mocal Thermostatic Sandwich plate SP1T ($90)
Derale Atomic Cool Fan and Cooler ($160)

and about $60 for the following:
Two socketless 90deg -8AN fittings (cooler end)
Two socketless straight -8AN fittings (sandwich plate end)
Two 1/2"MPT to -8AN fittings (adapters to sandwich plate)
6 feet blue socketless hose

And I'm using a PH3614 oil filter.

[AZ914]

Demick,

Thanks for the quick reply.. pardon the stupid questions:

Are you running a remote oil filter?
No thermostat but just a switch (coming soon) that you can turn on/off the fan?

[Demick]

No remote oil filter. The sandwich plate fits between the oil filter and oil filter console. The filter ends up about 1.5" lower than stock position, which is why I run a different filter.

There is a built-in thermostat in the sandwich plate that doesn't force oil through the cooler until it gets to 180F.

But as far as the wiring, you can add a thermo-switch that will turn on the fan at a certain temperature. However, the only one that I could find that fit in-line with the oil lines turns on at 180F. That was lower than I wanted, so I designed mine to run at low speed whenever the engine is on. This way, it keeps a little air circulating, but doesn't draw much power and doesn't fully cool in this condition. I will add a manual switch that will bump the fan to full speed.

Here is how it is wired. I have a relay that turns power off and on to the fan based on the ignition (gets power anytime the ignition key is on). But the ground wire from the fan goes through 3 ohms of power resistors, which is how it runs at low speed. The manual switch will bypass the resistors and ground the fan normally which will give full speed. Currently I can't turn the fan completely off except by pulling the relay, which is easy to do. I'll probably end up pulling the relay during the winter and putting it back in during the summer.

Sweet.. thanks for the information. (IMG:http://www.914world.com/bbs2/html/emoticons/clap.gif)

cool stuff. (IMG:http://www.914world.com/bbs2/html/emoticons/smilie_pokal.gif)

with temps hitting high 90s and 100s in the summer, I am probably right behind you.

thx

me too... trying to see if i can run a slim cooler up front in the valence....without cutting the tub..... (IMG:http://www.914world.com/bbs2/html/emoticons/ohmy.gif)

Aaron,

If you figure something out with the valance, let me know. I'd think that a front mounted oil cooler might work a little better but I don't want to chop (IMG:http://www.914world.com/bbs2/html/emoticons/sawzall-smiley.gif) .

I may go with Demick's setup but I am curious about what you are looking at. I wouldn't mind cutting a hole in my $100 valance. How would you get the lines from behind the valance to the longs? In the wheel well? Would you need a better pump?

[kenpolives]

I've got a similar set up on order for air cooled net (more $$$$ dam it) What did you up up the power wires to? I'll got webers in the car so could I just pull some power from the relay board?

Like I said, I used a relay. Power wire goes through a relay directly to the battery. The relay is switched on and off by a wire running to the pos side of the coil.

This is what I was looking for guys- thx. Search function wasn't much help- never is so I'm probably doing something wrong being relatively computer illerate. Thank God a 914 is computer illerate as well with carbs!

[EdwardBlume]

Classic thread!

[Beebo Kanelle]

Good Job! Additional cooling surface area is always gonna help.

A question: why wouldn't be OK to mount it inside the engine compartment? You have huge amounts of air exchange from the engine cooling fan.

[Dave_Darling]

It warms up the already-warm air in the engine bay. It makes things more crowded, and there's a lot of the engine bay you want access to. It puts the cooler up high, which can make things a bit more difficult for your oil pump. And can get messy very quickly if you have to get the cooler out of the way or drain it for any reason.

To be clear: None of those are absolute reasons you cannot do it, but they are inconveniences that can be avoided.
