PURPOSE: Group buy feeler.

HISTORY: Porsche OE radiator is marginal at best. It has plastic end tanks that are crimped onto the center tube section. When the gasket fails (approx 60,000 miles +/-) you get coolant leakage. Plastic is also a poor thermal conductor.

SOLUTION: Install a custom made all aluminum, welded radiator. Better performance, increased service life, long term savings.

CONCLUSION: I have contacted Griffin Thermal Porducts (www.griffinrad.com). They are a true manufacturer with complete engineering on staff and a 120,000 sf facility in South Carolina. They manufacture individual custom radiators, racing radiators for Winston Cup, large industrial heat exchangers, to full production run OE replacements.

I have done my homework and no other radiator available will surpass the Griffin product. The $480 Factory part is plastic. The $250 E-Bay radiator is just components that someone buys off the shelf and assembles. It uses brass fittings that will cause electrolysis and premature failure. It also has no warranty.

I sent my OE radiator to Griffin and they are willing to make a direct bolt-in replacement all aluminum radiator. This radiator should be approx 15-20% more efficent in heat rejection than the OE radiator. It will also last longer. Griffin incorporates a unique manufacturing step to assure long life. Each radiator is reinforced with a special high temperature epoxy. This adds tube to header strength, prevents vibration failure, increases corrosion resistance and gives an extra level of leak protection. This process is Q1 approved by Ford Motor Company, one of the toughest standards in the industry. This radiator will carry a two year warranty.

GROUP BUY: The price for a single unit is $575. Five units will be $489 each. Ten units will be $365 each.

I do not install cr@p in my car, only to replace the part again later (or should I say sooner). So am going to order one of these for my car. Is anyone else interested? I will place my order on 3/18, so speak up!

i feel i need one, but can not for the life of me afford that! i hope it works out for you, and want to give the suggestion to post on the turbo/s boards, i would think all of the super high performance cars over there would be very interested in a piece liek this.

Jakerx

oh la la. i'm interested.

Thanks, Bill... I'm interested in this as well! I had a Aluminum Corvette core clipped and shoved into the radiator shell for my Austin Healey 3000 (r.i.p.) and it made a world of difference.

$365 is not bad...

Jakerx

365 is actually a great price in my opinion

Bill

Ok! So far we have 9 interested in a group buy.

One more and we can all get this "too cool" product for the exceptional price of $365 each.


CROSS POST FROM THE TURBO BOARD - Go to the turbo board to see questions.


cas951 - With as close as we are, yes I can wait for 10. Since I wont be able to drive my car until I get a new radiator......PLEASE can we have one more step up to the plate!

Tom M'Guinn - Yes. According to the Griffin engineer, the all aluminum radiator should provide approx 15 - 20% better cooling over the stock radiator. In my mind a must for modded cars that produce more HP and thus more heat. Yes the Griffin rad will be a direct bolt-in replacement. That is why I sent my stock turbo radiator to Griffin, so they can duplicate the mounts/dimensions exactly. This brings up a point, I looked in the PET and it appears that the NA radiator is a different part number than the turbo radiator. So if they are different, Griffin only has a turbo radiator to match. And lastly, I do not know what a NASCAR radiator looks like, but the one I have been discussing will be all aluminum, no black paint. You will not be able to see the radiator from the front as the AC condensor and inter-cooler are in front of it. And in the engine compartment the fans cover the rear.

Ski - Since I have never chaired a group buy, how do I contact John D to ask permission?

Zero10

Just PM him, or wait until somebody reports this

The turbo radiator is taller than the NA radiator, necessitating a longer lower rad hose, and different brackets on the bottom. With some coaxing, a turbo rad can fit a N/A car, just not worth the trouble IMO.

Bill

Thanks Zero10.

I will PM JD.

Bill

Ok, ten!

I have just sent John D a PM, asking for his blessing on this group buy.

Anyone else that is on the fence, this deal is too good to pass-up, get in on it! I can't guarantee it will be there after this purchase.

That is a good deal at $365. I bought the copper & brass rad that Perfromance Products has been selling for 10 years or so. It's been in my car for 8 years with no trouble at all, but was $400 back then! I was careful to be sure it was isolated electrically because of electrolysis concerns (aluminum being anodic to both copper and brass). I said the hell with it after the 3rd aluminum/plastic unit went bad (cracks in the plastic tank at the crimp). If I didn't have this already, I'd certainly be in on this group buy.

por1984

i would be interested depending on when they will be completed and shipped. any idea on time frame?? thanks bill

Jim 944S

Bill, I have an "S" and my parts book is at home... is this the same radiator as the 8 valve car? I'm asking since I noticed that the Turbo is different.

Jim 1987 944S

Jim 944S

OK... I read the entire post and checked vertex. I cannot use the Turbo radiator, so I'm reluctantly OUT of this purchase. DAMN!!! It really seems like a great opportunity!!! If there's any opportunity to do this with the NA cars (5spd) let me know.

Bill

Sorry guys, I just figured out that the two radiators were different. If someone has an example of the NA radiator and is willing to send it to Griffin, I can ask my contact if you can be included in the group purchase. So far, three NA guys are interested.
