Gauging Interest: GT Oil-cooler Fan support Options

[gereed75]

Nice set up and to my “seat of the pants” engineering eye, it should be quite effective. Yes a larger exit area would be nice

The efficient design of heat exchangers in air flow and their attendant plenum “systems” is very complex. Compared to what is done in places like Formula 1 and aircraft design, the 914 GT inlet and shroud is a very quick and dirty system. The addition of the fans kinda dominates the system’s airflow characteristics making the other design features pretty much secondary. It is also the fans that will make it effective no matter how clunky the rest of the design is.

It’s a KISS system. Don’t over think it.

I don't personally like the traditional GT solution with the small louvers. I use the two access holes to the back of the floor. The round covers are held in by seam sealer so there is no cutting involved. It wont work with the stock style GT shroud but I want something custom anyway. I'm going to convince Ben to make me a stainless steel shroud - (IMG:style_emoticons/default/biggrin.gif) - I think it will look cool and I won't have to worry about throwing things in the trunk and damaging a glass shroud.

@mepstein - Thinking to do something in fiberglass after seeing the unit I had and how much work it needed (IMG:style_emoticons/default/shades.gif)

Ben, I did my fabrication 21 years ago durning the restoration. I just mimic the factory design. No fans, no over heating problems ever. I’ll add pics below.

Unlike Armando‘s, all sheet metal openings that I cut on the car I retained a return edge of the 90° angle to create structure.

Armando has a very good write up of his journey to duplicate the factory design. He spent all kinds of money fabricating his design.

Armando‘s design


Factory tow hook design I believe.

It would be nice if you opened up the “air” exit on the bottom floor of the trunk. The louver slot openings are tiny. The exit side should be twice the size of of the opening, less pressure more flow.

In fact, I bent the floor sheet metal down on the leading edge of the air exit to help suck out the air creating a suction. Its the same theory as the little plastic flappers on the bottom of the car at the engine bay..!

@Bucci - Pretty cool. Do you have any photos without the shroud? Also, did you retain your on-engine cooler?

[gereed75]

Looking at the Armando thread and the work that went into that cooler and plenum setup, and as much as it represents the factory effort, I would say that the factory effort was significantly better than quick and dirty.

It is all about directing and controlling airflow. The air is being driven by pressure differential and that differential is surprisingly small in these kinds of systems. The effort done to smooth and contain the airflow in the factory setup is what optimizes the flow and makes it work.

Again, the addition of fans kind of changes the whole equation and makes up for a lot of less than optimal design features.

Any chance you could supply it with the fans and wiring harness?

@mepstein - Not a problem at all. Can supply wired with a male/female connector ready to install. (IMG:style_emoticons/default/beerchug.gif)

How about just the hardware, no fans. Curious if my existing spal fans will work? What are the fan specs?

@Steve - Also not a problem, will PM you spal fan specs (IMG:style_emoticons/default/bye1.gif)

@riquemar how much for just the bracket?

@RiqueMar ,
Still doing these?

@RiqueMar ,
Still doing these?

I emailed him about 2 weeks ago and he said he was leaving for a vacation. He didn't say when he was going to be back. To answer your question He was making a list of people that wanted these brackets or whole setup. He was going to work on it when he returned.
I can send him an email to see where this stands and to check in here.

Hi All - Thanks for the patience.

Traveling alot for work currently. With COVID still a hot-topic, I've limited travel to just myself to avoid our installers being in the field.

Yes, still doing these. To those interested in just the bracket, total is $128 before shipping. Comes pre-bent, painted, and ready to install fans.

Hi All,

Back in California and filling orders now, PMing individuals now!

[RiqueMar]

Thank you to all who placed the first-set of orders, shipments going out tomorrow. Very proud to show these off! (IMG:style_emoticons/default/smilie_pokal.gif)
