Today was productive.

I fabbed the bracket to mount the cooler, some attachment points in the front trunk and painted everything when I was done. Some pics:

mounting point before paint:

A good day overall. Now to decide on the air inlet and exhaust configuration, as well as where to run the oil lines.

I was thinking about mounting some puller fans behind the bracket. Any suggestions on the best place to source these?

Looks great, is that cooler an oil Porsche unit or an Mazda?

Looks good. White cars are so cool. They make touch up and spot painting so easy. (IMG:style_emoticons/default/beerchug.gif)

Wish Home Depot had Zambesi on the shelf.

Looks great. Hey did you see John Petersons oil tank thing? Maybe you could buy his old tank and have it stripped and repaired.

Thanks.

The cooler is indeed an RX-7 unit that I had some AN -12 fittings welded to. It should work fine.

I am going to use one of GPR/Patrick's tanks in the stock location, but the Peterson tank looked cool too.

Thanks for the tip on those fans. (IMG:style_emoticons/default/bye1.gif)

Looks good but i would highly recommend to mount that cooler using rubber spacers.

I don't think a hard mounted cooler will last long.

(IMG:style_emoticons/default/agree.gif) I would also say that you should consider using radius type 90 degree connectors for the cooler for better flow and less restriction like the ones in the pic....

Thanks Andy. I wasn't aware that vibration would affect the cooler.

What do you use without raising it too much higher? Some high durometer rubber spacers?

Any suggestions without having to re-engineer the whole thing?

That's interesting, because when I asked the guy at the local hydraulic hose and fitting shop, Orme Brothers, that question he said that given the pressure and flow volumes we use in the automotive applications there is not a measurable improvement from one fitting over the other. It seemed to make sense and he was very emphatic, so I bought the tight 90s. (IMG:style_emoticons/default/headbang.gif)

Speaking of better flow and less restriction - on how many mid or rear engined cars with front coolers did Porsche put the thermostat in front? I'm going to guess zero.

I found this in McMaster-Carr. Do you think this would be adequate? It even has an 8mm hole through it for my mounting bolt.

Even thought Porsche may not have put the thermostat up front many of us have and that doesn't make it wrong....it's not the popular spot for it but mine and others work fine with it there....and what does that location have to do with flow and restriction???

And how much flow & pressure is there?
Sure, I know one & have a SWAG on the other but ask to see if your salesman does.

BTW,Mounting the thermo up front makes the pump work harder moving oil....particularly when cold....but seems to be an OK way of plumbing it in.

Dunno ...

I mounted mine "floating" to minimize stress on any mounting points.
It sits in two channels that are padded ...

I've used this style http://www.mcmaster.com/#rubber-isolators/=bfktec to mount my fuel pump,ignition box on another car I'm working on and they've worked great but everyone has there own fabrication ideas .....

Thanks for ther input Jeff. I think Neoprene will be a better material than PVC since it is heat rated to 180F vs 105F.

We do need to get together after work one day and meet. Perhaps Wednesday night or Thursday night this week? (IMG:style_emoticons/default/beerchug.gif)

The idea of a 'floating' cooler is that if the chassis twists, the cooler doesn't. A twisting cooler can workharden the aluminum and crack. There are a million ways to do it, but the 'rule of thumb' is that a bolt/fastener should never touch the cooler and the chassis/bracket at the same time.
