6.0-928S

I'm in the matket for a new aluminum radiator. I can weight the advertised features of all the aluminum radiators on the market myself but I have no experience with any of them. What is the best rad out there from those who've had experience with them? Pros, cons? Including fit & performance, workmanship. Even what you've heard. Thanks in advance.

928 Internationals. Great unit.

Wait one week.

I will. They are being built, as I write this.

Solving all the problems.

I can wait . What am I waiting for Greg? Yours? Or are you seconding the 928 Int'l rad?

Thanks, Hammer

After 2 failures in about 6 years, I now stay clear from the integrated cooling units (OEM & Custom Built). I have found that the best option is separate (e.g. individual) cooling units for Water cooling / oil cooling and transmission cooling.The separate cooling units makes the diagnosis / removal and repair so much more easy.

my 2 cents worth

I'm very happy with my 928 Intl rad.

A separate unit for an auto transmission is fine, but only if it has it's own pump and fan. One good reason for putting the cooler in the radiatior is to keep the cooling function when in slow traffic, in the city waiting at stoplights and waiting for a herd of sheep to clear.

I finally got so frustrated with what I was working with that I had to do something...it just shouldn't be that hard. I've been charging an extra 3 hours to install the aluminum radiator...and found that I was loosing my ***...it took way more than that to make them fit and work properly.

I'm having a completely new radiator built that will fix all of the problems I've been having.

First batch here, this next week....maybe the beginning of the following week.

Greg,
I'll wait for a better product every time. What's the cost? My car is an auto BTW.

Exactly right. Not many people get that.

Porsche moved the oil cooler out of the radiator to get more cooling capacity, in 1990. They stuck the oil cooler under the radiator. This worked OK, in Europe, where the roads are more open and air can get through the cooler. This absolutely sucked for the USA cars...these babies sit in traffic and the oil temperatures. go through the roof. In the summer, here in Southern California, we've seen oil temperatures of 300 degrees...in traffic. (Ever wonder why the cam lobes on the late S4, GT, and GTS cams look like crap...wonder no more.) Yeah, the oil temperature drops, once you get some air moving past it...but it is hell while it sits there and idles with the A/C on.

We now have oil cooler hoses, made up, that allow the customers to use both a cooler in the radiator and the external cooler. The best of both worlds. Rapid oil warm-up, since the radiator warms up faster than the oil. Good cooling while driving down the road (that air oil cooler works good, when there is air going by it.) Good cooling while in traffic (again, the radiator oil cooler.)

Every single one of those cars needs this oil line modification and an oil cooler in the radiator.

We're also doing this, for the automatic transmissions. Hoses available soon.

Here's a plug for Carl's radiator from 928 Motorsports. I didn't need either internal cooler but he offers them as well, and they are extremely nice. I have zero problems with it, car runs cool as a cucumber and it is simply a beautiful piece of work. I did have to trim the lower rubber radiator pads by about 1/3 to get the larger aluminum unit to fit but otherwise zero fitment problems. Went in like a glove, everything lines up and fits exactly as it should.

I'll have firm prices, this next week. We are going to only supply the radiators with the oil coolers that people need. (We won't be installing transmission oil coolers into stick shift cars.) Therefore the prices will vary, a bit.

If you read my previous post, I think that almost all 928's need a radiator with an engine oil cooler...although we will make radiators without that cooler, for the people that don't want to change their oiling system.

Our goal was to make a new, better radiator, at/near the same price as 928 International's current radiators. Mark is aware we are building a new radiator....we've discussed this, before I decided to have them built. Hopefully he will sell ours, when he uses up his current supply.

So your rad will be a bolt in replacement for my car with both coolers, trans & engine oil, in the rad?

Try and picture/imagine me using something that Carl had anything to do with....

I can't picture/imagine that happening, either.

Building my own, from scratch, thank you.

Without fitment issues, cooler issues, etc.
