Does a Turbo bumper really work on a Carrera / how to make it work?
The Turbo bumper, like the aerokit/GT3 bumper, gives you almost no front end lift. But it’s much less likely to get banged up by speedbumps, driveways, and perpendicular parking, because it isn’t quite as low in the front, and bexause the lowest part is a rubber spoiler which I presume is flexible, and not too hard to replace.
The problem is that it is designed to accommodate slightly larger radiators and air conditioninng condensors, as used on the C4S and the 40th AE. So I’m wondering what happens if one uses it on a regular Carrera. Where does the air that would have flowed where the C4S radiator extends beyond the Carrera’s? Does it end up causing a lot more drag or lift? Do the Carrera radiators get less air because the standard bumper would direct some of that air to them, but now it’s lost? Or does the radiator surround or something else make sure all the air ends up in the same place anyway?
If just bolting a Turbo bumper on doesn’t work for such reasons, is there any solution?
Alternately, does anyone make a Turbo style bumper for Carreras with the radiator intakes modified so the air gets to the right place?
Any insight into this would be greatly appreciated!

Just throwing in a link to a previous thread and car with this transplant. I'm interested in this question also.

I have a turbo bumper on my 996.2 targa. I've never had any overheating concerns and I run it pretty hard at a local track. Although my oil pressure does drop significantly when it is hot which implies the engine gets pretty warm.
I wouldn't be concerned at all with the turbo bumper for street driving. For track driving it still seems to be okay and you could always install a third radiator when you do the swap.

Changed out my base bumper with a Turbo Front bumper but decided to keep the original duct work in order to funnel the air (i.e. split) through the front vent into the rads. I was ready to purchase the newer C4S duct work, but the temps stayed right at 180F with no problem with overheating. My only concern is that some air may be getting trapped above the base duct work, but so far no issues.

My experience is with a 996 Turbo the front bumper/air dam is quite low and scrapes almost every where. The part which hangs down the most is the air dam and it is not real flexible. If one is not careful entring/leaving driveways and not pulling too far into a parking space it can break. A new Porsche air dam is several hundred dollars. There are less expensive ones avaiable but I know nothing about how they fit, their quality, etc.

Let me know if I can help further.

Do you realize that Porsche charges $150 - $200 each for the front black vents on the Turbo bumper? Simple piece of plastic that didn't cost 25 cents to make. ha!
Now on the other hand, if the OP doesn't have a Carrera C4 tip, then more than likely he doesn't have the center radiator; therefore, he won't need the center air dam than funnel air below the car. Maybe the OP can post some pictures.

Absolutely right!

This air dam (and the other aerodynamic aids of the Turbo) works very welll as my experience with my Turbo is it can maintain a very stable and reasonable coolant temperature even when operating in extreme ambient temperatures, even with just one radiator fan working.

I would like to reference it to the OEM parts break down. Porsche tends to use several names for the same thing.
Are you talking about the front lip spoiler - part number# 9965055550201C
