Any successful radiator in engine compartment conversions?, Or other than front trunk installs? Options

[mepstein]

it's easy to cool when the car is moving. It's driving through a slow moving traffic jam in the summer that has my concern.

[DBCooper]

Yup, lots of theory to go around, but to answer the original question, no, I don't think anyone's done it successfully. Well, Lamborghini did, I guess, but then in the same situation Ford, Toyota, Ferrari and GM all used conventional front radiators.

So go for it, just please don't re-body the car to look like a Lamborghini.


Aw heck, screw that, if that's what you want then go full Lambo.

Same idea as the 914+Jeep,
Better tho.



Can't think of a reason why a dual rad set under the targa wouldn't work.

I love to watch this subject resurface. A lot of arm chair engineering and suppositions! While the idea has merits I doubt I would ever do this even "if or when" someone "nails it". If your wondering why then it's most likely because you haven't done one of these conversions. Not trying to be snooty or snotty, just a word from the experience side. First and foremost is the fact that you will spend countless hours refining your design and a very big chunk of that time is thru the "Hell Hole". As we discover, the work in that area is made easy by "QUICKLY" removing the deck lid with just 2 10mm bolts. Mine has come off at least 10 times since it first started and is off again as I type this. (New electrical modification) I don't want to guess how many times it was on and off all together. (IMG:style_emoticons/default/dry.gif) That being said' if I had to work around a radiator or remove, drain and fill that SOB every time I needed to work in that area I would have abandoned this project long ago. Secondly, why worry about cutting up a front trunk? Once you have a good water cooled system in place you will never regress and re-install an air cooled. Besides, all of those areas can be welded back up quite easily.
I don't wish discourage anyone from trying something new or attempting a new design but I doubt that I would ever go this route even if someone had a proven design just because I know that occasional maintenance is needed in the "Hell Hole". Just my 2 cents. (IMG:style_emoticons/default/beerchug.gif)

the advantage of front mount is that once the car is moving you have air moving through the radiator with out needing the fans.

having the radiator out of the airflow you would need the fans to run all the time.

even though there is an negative pressure area at the engine lid I doubt it would be enough to draw enough air flow to cool the radiator enough with out the fans running.

if you a using an engine driven fan then this is not a concern as with a Porsche six or the t4. but if using the electric fans the constant high amperage draw might not be desirable.

[veekry9]

If you planning to race it exclusively,a rad mounted in the rh seat area is possible.
Ducting to direct air to and from the rad has minimal weight.
A passenger seat would negate the proposition.

[SirAndy]

So, running an air cooled big 6 gets enough air. Why wouldn't a large 4 get enough with fans?
Inquiring minds want to know.

Exactly ...

No, not exactly ...

On the air cooled engines, there is a clear separation between the intake side of the engine and the underside where the hot air is expelled.
Without that separation, our aircooled engines would be very short-lived.

I have yet to see any watercooled solution that followed the same principal.

[SirAndy]

water is a more efficient medium than air so

And the (armchair?) engineer in me cringes at that statement.
Because last time i checked each and every "water-cooled" car i know of uses air to expel the heat from the system.

Where do water cooled 911 s mount the radiator

Cause it would seem if it's boxster style , on both lower outside
Bumper area

That they intentionally stayed away from big single right in front style
????????

????

?

I see no reason no to implement what ever current water cooled Porsche s
Are doing

[Chris914n6]

^^ most newer mid engine cars do the corner rads and exhaust the air out the wheel well. Otherwise it cuts into the possible trunk space and exits out the hood or under the car, both are less than ideal.
The 914 doesn't have the space unless you cut into important parts of the chassis structure or make a deeper bumper.

Could mount them at the sides.Something like this.

Here is my rear mounted radiator in my 904 kit car (engine is a Subaru WRX)
I'm using a stock Subatu radiator and fans, the engine runs at 195 degrees. I'm
using the air coming off the rear deck to supply cool air into the radiator and
having the air exhaust under the car (low pressure area when moving)

Here are the pictures

And that would fit in a 914 how exactly?

There's alot of room for the radiator out in back... unless you want to save your rear trunk. Great looking 904 by the way!

Just to prove a point. As long as you can get the air flowing thru the radiator and exhaust it (air flow) you can mount the radiator or radiators any were.

[JRust]

My NA 2.5 subaru leaves a bunch of room in the trunk as stated. I also don't have any cutouts in front for air flow. It is just the stock holes without the rubber plugs in them. My car has zero cooling problems with it up front. It does exit through cutouts in the wheels wells. It also pretty much wipes out my whole front trunk. If we could get a solution to get headlights in the turn signal buckets. I think the dual radiator boxster setup using the front light buckets would be killer. I think with a flared car you could do those in the engine bay on each side with some inlets. I haven't seen to many inlets on the side of a 914 that I have really liked.

I think if you could have a short but wide radiator. Say 10" by 40"+ it is possible. If you could mount it low in front of a NA 2.5 suby. I think it could work. Only because I know how little it takes to cool mine. It would take some inlets in the rocker at the least. Then some pretty powerful fans to help pull it through. I think low instead of high for working on the motor. If it's up high with a GT lid it will definitely interfere with getting to the motor for basic maintenance. I would love to see it done (IMG:style_emoticons/default/confused24.gif) . I don't see it being me that does it though (IMG:style_emoticons/default/evilgrin.gif)

[Andyrew]

I think it has all to do with the size of the motor and the ducting. I would almost guarantee you a 1.8-2.5L could easily survive a small radiator in the engine compartment if there was a proper amount of both ducting with ram air and cowl induction.

How about Targa top mount

As crazy as it sounds , it almost makes sense

Sure is a beautiful design,tho I can't make out the origin of the car.
Did you do the build personally?

A lot of questions looking for answers.
1 rad or 2?
Up high or down low.Add a scoop or leave it stock?
20Ft of hose or 3?
How to bleed the lines as they make their way forward and back.
Should you make your trunk useless.
It's not real,but should you make a drawing after using a tape measure and Gimp/Photoshop/Draw etc..?
A custom rad or a used one?
