I installed the very same radiator a few years ago, and pretty much noted the same issues. I do need to mention though that I thought the build quality of the radiator was top notch. I expect many many years of great service.

The next time I take the radiator out for my TB and WP service I plan on also trimming down the lower rubber mounts to let the radiator sit lower. My concern is the overflow nipple. It sit 1/4" higher than the stock rad. I also plan on adding the new 928 Specialist fan assembly. It's a higher rated cfm fan set that stock and is also smaller to boot.. That will take care of the slight added depth of the C&R.

All for all, my opinion, I don't ever plan on going back to the Behr unit.

Convert it to a 5-speed. Roger has some manual gear boxes lying around me thinks.

Hey, Mister monster-big-horsepower-supercharged-custom-piston-man , why haven't you chucked the stock fan shroud and substituted the little electric fans that come with the SC kits?

On that note: I sure don't see any problem at all with the 928 International radiator for folks that have a setup where the stock S4 fan shroud is already history. In that case, presumably, extra cooling capacity over the OEM unit would be a good thing anyway.

I agree. It is nice and, as I wrote, better IMO than the Devek unit.

It's hard for me to tell how my posts are coming across. I'm not trying to be critical of the 928 Intl unit. I just want folks to know what they need to look at and think about to fit it in an S4.

It's kinda funny though. Carl's post comes across with a mild tone of frustration. During the actual act though, he was all Mr. Calm Zen Master while I, hopped-up on his 105 octane coffee was all !@$#%$!@

Starbucks, ground into fine powder and put in a french press...turns Dr. Dave into Mr. Hyde.

I drove the car (50 degrees f today) for 1.5 hours, even stuck in Foxboro stadium traffic and no leaks or overheating. The temp guage shows the temp moving around quite a bit though, but without an IR temp gun I don't know if it is meaningful data.

Sure, it looks like a quality piece. As we all know there are many pieces that contribute to the cooling system working properly, the rad being only one of them...

I think the big diff between the Devek (Ron Davis) rad and 928 Intl one is the fact that the end tanks on the 928 Intl ones are welded versus epoxied (in Deveks case) or tabbed like the stock one.

The factory ones don't fail much (based on rennlist reports)..but when they do..it's usually the end tank..hence the aluminum end tanks..first epoxied..and then finally welded...Plus the fact that a factory fresh one is like 800 or so and hard to find..

If mine goes..I'll get the 928 Intl aluminum one...and take the time to install it correctly..thanks to the tips above..

Personally i'm glad that there are options out there, I do know what you are referring to when you are talking ease of fitment and other niggly bits that come up when doing the fit. I always appreciate honesty when people are selling stuff, like when Jim Bailey told me about the strut piece for the grill of the early cars which is NLA from Porsche, he said it was a little rough. In fact when I got it it was pretty good and I was happy with it.

I also had to do this step when installing the C&R radiator on my 86.5. The picture shows the OEM Behr unit, the red is the area that needed to be trimmed for the intake ducts on the C&R. Everything else went together fine, but I also have not had a chance to test the cooling abilities as there has been two feet of snow on the ground here since the first part of December.

I also have one of DR's twin screw fan units on order to use with the C&R radiator. I will post a thread on how these two work together once I get the fans and they are installed.

Hi guys !

Anyone tryed 928 Motorsports Alu.Rad. ?

If your core is in good shape, it is easy to replace the end tanks and rubber gasket.
The biggest question is if the core is in good condition (not clogged or leaking), if it not then an all aluminum is like someone said is a great option to have.

My own tank replacement is still holding up, although in cold storage now, if worked great w/AC on and 95 deg. F. days this past summer.

I think the 928 Motorsports radiator is the 928 International radiator.

hhhhmmmmmm

Yes we sell Carl (928 Motorsports) our C and R radiator which like the Kemp Tension tool is an exclusive product which exists BECAUSE we guaranteed a sufficient minimum order and sales to get them made. We wholesale them to other retailers . I recently put the aluminum radiator in the old very brown 1980 at home with out the lift or air tools and it took about 1 1/2 hrs total and fit right in. The C and R is slightly heavier than the original Behr and holds a bit more water neither of which is such a bad thing

I installed the 928 Intl radiator. Took me about 30 minutes out and in. The only thing I found was the replacement stood a little taller, so I leaned the unit up slightly on the driver side to clear the hood. All else was great. And most of all, my car runs much cooler and no more leaks. Yehhhhh no more antifreeze smell. Great product, just pricey, but why?

It costs less than the Behr. This is a problem?

I was not bashing the product, and have high hopes for the heat shedding ability of the new unit. 928 Int has always been a stand-up place that gives 100% for the 928 owner.
