28 tube oil cooler?

[VaSteve]

Does the 28 tube oil cooler have a better name? I want to start searching for one and 28 is too short for the seach engine. Also what year did these come out, early Carerras?

Thanks!

[klaucke]

try including "brass" ?

You can use the wild card with it to make it 3 characters 28*. You can also use google to search the appropriate forum without these 2 character restrictions.

Why not get a Carrera cooler? Are you doing a period-correct update?

I think with the real Carerra cooler, you have to move the horns, and wire it for the fan. I just want a bolt on solution. See my other threads for why I want to keep it easy as possible.

I think they came on the 81 to 83SC and possibly the 84 Carerra. Then they changed to the finned style cooler.

As Klaucke said most people refer to them as a 'brass oil cooler'. When I purchased my car it had an after market finned oil cooler installed and it got a small crack in it. I replaced it with the brass cooler and it works very well at keeping temps down.

I have been told that if you intend on tracking the car you should upgrade to the finned one, otherwise the brass cooler is ok for normal conditions.

Steve,

The 28 row cooler is not as effective as the carrera cooler. You can install the Carrera cooer w/o a fan and moving the horns is a piece of cake. To make things even cheaper, check out the 'off brand' coolers (bigger and cheaper then the Carrera). Just make sure you get good air flow to the cooler (remove lights and duct around) when on the track and things will be fine.

Some would disagree with that statement. Some belive the carerra cooler more effective in slow moving traffic, but less effective on higher speed situations. The 28 row is primarily radiant cooling while the carera cooler uses more convection cooling effect. Maybe check out Bruce Anderson on this for a more respected "opinion". I don't know if there is anybody with data to support their opinions. That would certainly be more helpful than a thousand opinions.

Damo,

To answer your question my 84 Carrera came with the 28 row brass cooler. I don't know if it was an option or choice between the two or not. I don't think it was but may be wrong. I can't speak to the other carrera cooler but mine works fine in stop and go traffic which in this area is pretty bad. I'm sure Charlie can back me up on that.

"primarily radiant cooling"

- I doubt if either of them loses a significant amount of heat by radiation. Has to be a different reason.

The 'conventional' wisdom I am familiar with says exactly the opposite. In particular, if air is ducted through the radiator type 85-89 cooler, normally referred to as the "carrera cooler," it is quite effective at reducing engine temperatures during the high load but quickly moving conditions at a DE, even with no electric fan. Due to much less surface area (including fins), and substantially larger frontal openings, I personally do not believe the 28 row cooler to be as effective in this situation. I have not experimented with the 28 row cooler in (mostly stopped) traffic, but have heard that it is fairly effective. in this situation the 'carrera' cooler sans fan is not particularly effective.

I do however view the installation of a 'carrera' cooler to be bolt-in. if you get the elephant cooler you'll get all of the right parts. the lower bracket is recommended to be welded in but it can be bolted. The relocation of the horns is very easy with some galvanized strap.

K.B., I think you've got it backwards (although I honestly don't have data to support my point). The Carrera cooler needs airflow to work effectively, which is a limitation in stop-and-go traffic, but not an issue at speed. The 28-row cooler acts like a heat sink, which is good in stop-and-go traffic. Adding a fan will address the shortcomings of the Carrera cooler, but won't do much of anything for the brass model. On track days, the 28-row cooler typically comes up short.

[K.B.]

Yup, I did type it backwards.......... Long day. Thanks Jack. Randywebb, Radiant cooling must have some effect, or those Elephant Racing finned oil lines wouldn't be effective. My old house used to have a "radiator" in every room for heat. They looked a lot like the 28 row radiator.

at FIR in AZ with 100F track temps i get 13min out of my sc turbo...then its reading 230....

cutting a DE sesson short sucks alot...
