The rear was slightly flared from when it was new. So far I don’t know how to post more than one photo at a time! The Webers on mine work flawlessly. Fires up hot or cold immediatly almost like FI. It was dyno’d at 235hp.


Freeman, so nice to see you posting on this site! Could you elaborate further about the rear flares being done when it was new? Does that mean you finally did confirm they were done at the factory? For those that don’t know, this was my beloved car for 25 years! Here’s another pic of these unique rear flares.

Michael, sorry for the hijack on your thread.


Steve, nice to see you here as well! Back in 2019 I visited the Porsche Museum with my ex-colleague, Porsche designer Grant Larson. We didn’t find any documentation on the rear flares. We did however get access to the Piech 914-8. We made a template over the rear flare. It matched very close to mine. So, it’s still a mystery (IMG:style_emoticons/default/confused24.gif)

Way to go Michael. A brave endeavor !!!

Saw your spotless car over at Chris's ...beautiful as ever...I can see why Chris is a little hesitant about mixing your car with even the hint of welding. No doubt I'll be spying on the progress of the seat belts and want to see the details of the fan install...a project I might need to copy and paste on my car.

It happened it was the year the Porsche Museum was celebrating 50 years of the 914!

What belt retractor and receiver are you using in the seatbelt upgrade

I did this back n the eighties on a car I no longer own and now can not remember the details. I seem to recall I used late 914 or VW belts/ retractors

Would like to do this on my car now. Love to drive it but those old belts do not inspire confidence!

My car has the PMS front Setrab cooler along with dual fans (on a manual switch under the dash). In -most- normal driving situations here in SoCal, just the cooler without the fans works pretty well, when temps pop up a bit (driving hard or sitting in traffic) I will flip the fans on for additional cooling, have considered just putting them on a thermo switch so they kick on or off at temps but doing it manually isn't really a big deal... But then again I also have that massive Petersen style oil tank with 12-14qts in it --This is a pic without the fan shroud in place (IMG:style_emoticons/default/chowtime.gif)

This is an interesting layout. Do the fans get in the way of ventilating the heat out when the fans are off vs having the fans mounted to the cooler? How big is the inlet hole on the bulkhead?

For anyone interested, the oil cooler and fans in Eric's car appear to be the same cooler and fans I just listed for sale in the classifieds. http://www.914world.com/bbs2/index.php?showtopic=369378

The fans don't seem to be in the way as most times I'm not even running them and it takes a bit to come up to temp... inlet pics:

get access to the Piech 914-8. We made a template over the rear flare. It matched very close to mine. So, it’s still a mystery

How did you pull this one off?

Either way, very cool

It was through my ex-Porsche colleague, Grant Larson. I was a Porsche designer in Weissach 1983 to 1990. Great years to be at Porsche!

Michael opted for a dual-pass Setrab cooler and three fans. Setrab doesn't offer a fan mount set up for that particular cooler so it's CAD/plasma table to the rescue.
Here's the start of the fan mount. The green lines indicate the edges of the cooler core, the outer shape is the cooler body. This just gets me started on the fan positions.
Now I need to work out how I want to mount this to the cooler. I think it'll be sections that'll fold over and serve as the attachment points.

Parts have arrived- Yay! I know Chris wants to get this off his plate- and out of his shop. I am looking forward to going to pick her up and get busy with the 3.6 implant. Thanks for everything Chris; I am proud to have you working on this oil cooler set-up as well as the seatbelts. (IMG:style_emoticons/default/beerchug.gif)

I'm working up a one-piece cooler/fan mount with built in front lower shroud. Typical At The Red Barn approach: Do as good a job as possible on the first attempt but be prepared for a do-over, once I see it in real life.
This design needs a couple mount holes moved and that lower shroud area widened.
Off to fab V2...

Looks NICE!

I prefer the fans on the cooler versus fans attached to the floor over the lovers.

Not picking nits here but maybe add a few more holes to that backing plate so some air can go trough without having to hit the fans?

I see no benefit to only having those 3 holes for the fans. I'm guessing you are not trying to "funnel" air through the fans.

RE: comments about how the fan mount, clearance to the cooler, vents in the mount, etc:
Every pic I can find, and specifically the ones on the Setrab site, show the fans dead against the cooler with no other openings. Note that I spaced Michael's fans back .5".
I'm certainly not saying y'all don't have valid comments. I'm no expert so I'm thinking we'll go with what I've done, test it and if mods are needed, we'll go after them at that point.
I really do appreciate the input!

I like the flares and the green metallic. You don’t see many in that color.

I am sure it will work great. I am thinking it may not even need the fans but having never been to CA I really don’t have a good grasp on temps year round
