Radiators

Hey everyone,
I have been doing some digging on what donor sources I could use to fit a radiator in my car.

I had thought about using the Porsche cayman/boxster system which uses a triple radiator system in the nose of the car. But the price for them is prohibitively expensive as one would presume.
Not being undone, I continued to look for more options.
I contacted a racing radiator manufacturer to find out how much a completely custom made radiator would cost. With the dimensions of 12" x 26" x 3", no filler neck, and only side tanks with air bleeders installed the price was approximately 500 dollars.

This news was not bad, but also not good.
Being Im using a WRX engine, I will need adequate cooling for not only the coolant, but also for the oiling system, with enough cooling capacity left over to use the Subaru OEM AC system.

So I kept looking.

Thus far this next option has been the best in price, size, and even with optional oil cooling built in. Its odd size may lead me to new and uncharted placed with the oil cooling and AC condenser location. But heck its worth a look...

When thinking of sources for donor parts, you have to think small... Like the Lotus Elise....:D

Finally here is a picture of the radiator

In some versions this cooling system is actually mounted horizontally. Which adds a new dynamic to options in our car.

Per a retailer of this radiator (without the fans or duct work) the radiators dimensions are: The core sizes is 23.6" wide, 10.5" tall, 2.2" thick,the overall sizes is 29.3 inches wide (including the hose fittings and tanks on both sides)
If you use the 1x1x1" per HP rating rule of thumb, that would give a cooling capacity of 545HP which even for a WRX STI engine is plenty. This would leave cooling capacity room for an oil cooler, and AC cooling systems.

How much? how about $198 dollars plus 50 for shipping from one eBay seller.

So add a note in your build log. Given this radiators vertical height, it could be mounted vertically, at an angle, or even horizontally like in some versions of the Lotus elise.

Just an FYI for those out there wanting to go to a liquid cooled setup.

The seller also claims cooling capacity of up to 500 bhp with his setup.

I measured the vertical distance at the front of the front tub area. Inside the tub was approximately 12" tall directly below the lock for my hood.

^ I'm curious as to what those hoses are feeding. It isn't the brakes, and it doesn't appear to be the radiator.. but I digress...

I don't think you need to overthink this Yaughn. Plenty of off-the-shelf units out there that should easily meet your requirements. When I was looking, I simply googled the overall dimensions except the thickness and ran through the gamut of what came up. Many were linked to aftermarket parts for production cars. And don't forget to check your local radiator supplier/repair if you have one (they are getting a little scarce). Chances are they could build you one for less than you think...

The problem has been physical dimensions, combined with cooling capacity. Remember, for me at least I'm also trying to squeeze in a fuel cell in the nose as well.
The sterling is such a small car, that either the radiator is the size of the entire front of the car, or it doesn't have enough cooling capacity.

This kinda solved both issues, and with a very realistic price to boot.

Looks like a nice radiator, and compact too. I'd try to source on from a US distributor though - personally would be a bit nervous trying to buy something directly from China.
The side exits could prove beneficial for fitting into the nose of the car - allowing 90 deg. hoses to come off in any direction desired and go rearward.
I'm using an Afco Scirocco radiator in my build. It was about the best combination I could find in size, cooling capacity, price and availability to fit in the nose of my buggy.

For s&g's, a fiero radiator will cool a caddy 4.9 V-8 set up & the same radiator fits nicely in the front of my Cimbria SS, as posted on page 1 of my build. Just my 2 cents. Rick

Don't forget that you need to keep in mind the capacity of the radiator as specified by the donor engine. But even then, that requirement will change due to weight of the car, location of the radiator, how much air flow the radiator gets, how much ventilation the hot air has to escape, etc.

Here's a handy formula Probably not perfect, but will head you in the right direction hopefully.

As for myself, mines up front with a dodgy install, radiator is from a Holden Commodore (I think), with air coming in from the front and underneath, with all hot air escaping under the car. I've had the idea to 'steal' the idea from the Lotus in the OP.

Damn cyco--I'm confused--Man!?! 'Um do ya add & subtract by the 1-6 as a whole % or by a tenth of a % because of the periods in front of each ##? And not to be argumentative, but the A/C is cooled by a separate core, not as part of the engine coolant liquids flowing thru the radiator. Granted, the A/C core is usually in front of the radiator though. But the mustang figures are close to the caddy 4.9 which is 300 cubes, +/- a tenth of a %, so the fiero 2 row flutes is the preferred sorta "stock" GM radiator for the 4.9 swap into the lowly fiero, which will scare the hell outa many Camaros, firebirds & mustangs. Awh, hell way off track-again. ydeardorff, good luck with your search, your build, your way Man. I'll add, a person can over cool a motor, as they are designed to operate @ a certain temp for various reasons, which I guess is what you're figuring out, therefore the research. I don't know how to add a (me) dumb-ass smilie! Best of luck. Rick
