We've had a very nice dual-fan replacement for the 928 for several years and it's been just great. A perfect fit, and excellent cooling.

Only problem was there was no provision to hold the cold air intake tubes - so owners often had to chop off the tops of their old shrouds and mount them above their new dual-fans just to hold their cold air inlet tubes in place.

Well no more.

We have a nice all-aluminum air dam that fits perfectly on top of the radiator, and it comes with two stainless steel mounting screws to clamp it in place. Just transfer the weatherstrip from your old air dam/shroud to this new one, and you are all set.

We are making them available in satin aluminum finish or powder-coated in black as shown.

If you already have our dual-fan system, this air dam upgrade will just set you back $96.50.

If you need to replace your fans too - our upgrade to 2800 CFM fans will cost you $452 with this air dam included.

And if you happen to still be using the EGR/Air pump system, you will need a little filter for the air pump to replace the one mounted in the center of the old fan shroud.

We have this nice little K&N unit for $19.

Very nice Carl..

Thanks, Nic!

How exactly does the fan shroud attach to the radiator, im confused on that.

kelanel

Passes through the fins with plastic zip locks if I recall.

Carl Fausett

There are two tabs on the top of the radiator provide by Porsche/Behr. We provide two SS bolts to attach to those tabs. No mods are needed.

You can see the SS fasteners in the photographs at post #1 in this thread.

I see the ss bolts holding the air dam, but not the fan shroud itself

The weight savings of these fans over the stock motors/fans is considerable.

Carl Fausett

The dual fan and shroud are attached to the radiator with push-through radiator mounts designed for that purpose. They are provided in the kit.

IMO, something about pushing those cheap-*** things through a hundred(s) of dollar unique-to-our car radiator just seems ghetto. I'm sure I'm not the only one who doesn't want to do that....

You may want to to come up with a more elegant mounting solution, Carl.

Carl Fausett

You are not the first to express that.
We are not the first to mount fans directly to the cooling core.

The benefit that you may be missing is the seal of the shroud to the cooling core. Any gap between the fan shroud and the radiator will reduce the effectiveness of the fan, as the air can be drawn around the shroud rather than through the cooling core.

So, mounting the fan to the core - which creates not only a better seal (but also moves the fan blades much closer to the core itself for a better draw as a puller fan) - is a good thing and increases the effectiveness of the fan.

This is why so many of them are mounted this way now.

In contrast - a system of brackets usually holds the fans further off (and reduces their effectiveness) and creates the opportunity for brackets to come loose, mounting bolts and screws to fall out, etc. Just saying, the old ways we used to attach fans were not without their flaws, either.

So do you cover the cost of a new radiator when the radiator develops a leak from those things sticking through the fins on a car with one of your kits on it?

I know first hand that those glorified zip-ties don't hold on forever, they'll fall out just like nuts and bolts. Especially with the weight of even moderately heavy electric fans alone, never, mind with a shroud attached.

The zip tie mounts have their purpose and place, and it's not on a 928.

Lol damn Carl, I just bought an entire new shroud just to replace the damaged air damn air intake, if only you had been a week earlier...

Pretty neat Carl...thanks for the continuous innovation!
