Low Profile Fan Shroud
#136
Hans - you probably have never seen Todd's "lower-further-back" radiator placement have you?
What would you need from me (pictures, measurements) to see if your shroud would still fit? Its because of a Novi2000 placement in the engine bay.

On the good side, I have added a provision for a 4-pin weatherpack connector. This is entirely optional, and the mounting point is hidden by a flap for those who dont want to use it.
...
With the weatherpack connector, shroud removal is as simple as unplugging the single connection, and removing the two retaining screws. All can be done above the car in well under 1 minute....

Pictures showing placement. It was the best location I could find to make it accessible and reasonably concealed without effecting flow from any other flap.
A standard flap can be installed, concealing the mount for cosmetic purposes. by punching a .25" hole through a flap, it becomes a nice mounting and anti-rotational washer for the press-in connector mount for those who would want the updated connector. The round mounting flange allows the clip to be rotated/clocked in any direction for wiring routing preferences. In theory, the combination of the rubber from the flap, and the spring pressure of the clip should keep the connector clocked at the desired angle.

This is a good idea. I did it to the GT and fan extraction is just the two mounting bolts, undo the electrical connector and remove the fans. A couple on minutes work at most.

Mine is not exactly stock. I wanted the left and right to be mirror images. I also changed from 3.25" OD outlet to 3.5" for better plumbing options.
So, on mine, the inlet (oval) is 5855.5mm^2 and the outlet (72.2ID) is 4093.5mm^2. Factory is a bit less on both.

What's the number for stock oval outlet, in case you have that easily available?
#145
Actually, I gave you the wrong numbers. that was for the 3" outlet not my 3.5" I have a couple designs here, but all have the same inlet size. Factor in a wall thickness of 2.5mm from OD to ID and do a normal area calculation. I can make a custom part in any outlet size you need for your project.

Hans, any chance these will end up anywhere near pricing on those ff dynamics kits? It's obvious you're stuff is well thought out and well made, just trying to figure it out, you may not be ready to disclose any pricing yet. Thanks

Hans --
I am having a bit of a hard time following this thread, plus I don't have the time right now to go thru the whole chronology. EDIT: I did read it all thru and got some answers.
Some dumb questions, please explain to me like you would explain to a smart third grader:
1. What is the motivation for this project? Is it to fit a deeper radiator to a stock car? Is it to fit a supercharger or some other devices with the stock radiator? Or something else? EDIT: Seems like it's to fit superchargers etc. and have easier time removing the shroud.
2. Will this product come with a different radiator? Will it fit the stock radiator? If not, what are the specifications on the radiator you'll be selling with the shroud? In particular, the core dimensions? EDIT: Seems to fit both the stock radiator and the less deep custom radiator. Also seems to fit the deeper radiator.
3. What stock radiator shroud functionality will be accommodated? Will the early S4 cooling flaps work/be incorpodated? Will the smog air pump filter be accommodated? How about cars with and without the external oil cooler in the bottom? EDIT: The S4 cooling flaps are in front of this thing, so there's no reason to expect them to be affected. Seems like there are provisions for external oil cooler.
4. Any predictions about the change in cooling capacity? At low speed (with fans running) vs. high speed (mostly stagnation pressure at the nose)? EDIT: Some CFM numbers listed, but we don't know the stock flow capacity.
5. What's the shipping date for these?
Those come to mind first.
The ability to custom fit the air inlets is nice, as would be the extra space to run pipes etc.

Tuomo,
Basically the advantages of this shroud are:
-Narrower than stock - clears in-tank cooler fittings for easy removal
-Slimmer than stock - allows easy access to front of the engine (can turn engine with breaker bar)
-Lighter than stock
-Less current draw than stock
-Quieter than stock - curved fan blades instead of paddles
-Provision for custom intake options
-Provision for single electrical connector for quick-disconnect
-Can be removed in under 1-minute with screwdriver
I hope they will be available withing two weeks, I am waiting for the shrouds to come back from the metal fab shop, then I need to do a final QC check.
This wont be the cheapest option out there, but to the best of my knowledge is the only complete shroud replacement option with the upper airdam and intake snouts.

I have the first 10 sheet metal shrouds here, and they look great. I need to double check fit tonight, but think we are on the home stretch on this one.
I have contacted my fan supplier to see if I can get a discount with a "large" order. Depending on what discount is available, I may just assemble these units.
I plan on trying to take one to SITM for demo, and will post pictures and pricing as soon as I have a chance. The innitial batch is only 10 units, so if you know you want one, shoot me a PM and we can arrange a deposit.
Thanks
