Hans,

Thank you for your kind offer. I know the cost of having plastic parts made, and If i can use your air scoops I will - that could allow you higher production quantity numbers and perhaps help you lower your per-piece price.

I'm happy to look at them. Thanks for the offer. Let me know when you are ready.

Carl,

I should have the prototypes tomorrow. I didn't get a chance to go pick them up today. Next time there is an opening, I will try and print you one for evaluation. Those early parts are great, but one day they will run out.

In regards to the dual 10" fan, had you considered a one-piece design, like below. I just whipped this up in a few minutes using the posted spec sheet and the geometry from the shroud I modeled, so its a bit crude.

Thanks
Hans

That's a sweet piece on paper.

Remember you have to clear late-model oil coolers below the rad, and one or two integral oil coolers on each side, and provide for the EGR filter.

Hans - I note from your drawings that your cold air scoops seem to have an angle to them. That makes them early 16v models. The air scoop/funnel changed on the late model cars to a more straight shape. Perhaps you are designing two styles, and I am only seeing one?

I finally had a chance to get the new snouts yesterday. Pictures posted below.

Also, there is a prototype shroud underway. The flat stock has already been lasered, and it is in the process of being bent now. I think I may have an assembled unit as early as next week for testing.

So hopefully this option will be available soon.

Thanks
Hans

Very nice indeed!

Carl Fausett

Looks like a nice part, Hans!

Thanks!

After taking a look at them in person, I found a couple things I want to change. I reduced the wall thickness by .5mm and it flexes a bit more than I would like. I am going to go increase the thickness in the flat section, and then flare the junction inside the mouth a bit for better flow.

It is so nice to be able to actually hold a part for validation before committing to tooling.

I should have some spare parts to send your way as a sample soon if you want to take a look.

I have Revision5 of the "S4 compatible" intake snout designed, and it looks to be the final version. The last parts I printed in black were very nice, but after holding them, I saw room for improvement, so the production parts will use those, but the first prototype will get the Revision4 units.

I have two shrouds being built now from two different vendors to compare the process.

I also have the matching radiator being made, which I am quite excited about. It will be incredibly close to OE dimensions. The reason I say close, not exact, is I have opted to go with a *slightly* thinner core. The stock core is about 40mm (1.57" thick), and while I can source a matching metric core, the radiator fabricator I have selected has access to a 1.5" (38.1mm) core that he has had excellent reliability and performance with. There are some other fun features, which I will hold back on until I have the first unit in a week or two (core is a custom order, so will be delayed because of the holiday). This should be good news to Murf car owners, as the radiator will be compatible with the front mount Vortech.

Pictures to come soon of the shroud, and a new thread for the radiator when its in my hands.

Thanks
Hans

^^^ OK..was that printed? flipp'n unbelievable!

hans14914

Yep, and let me tell you, in-house FDM really speeds up development.

I would normally wait to post pictures till I had something in-hand, but these just came through by email, and thought I would share some pics of one the first physical prototype shrouds. Cant wait to get it all assembled and start some testing.

Schweeeeetttt!!!

DZGunner

Send me one, i'll test it for ya.

Ducman82

yay! something else to spend money on!!!! Hans, Greg, and Roger always end up with all my money...

OMG!. You are using a spec that is less than the typical Porsche over-engineered and over-built product? lets see, your proposed radiator is going to be 1.9mm thinner? Thats the equivalent of a fat 1/16 of an inch (3.2 mm = 1/8 inch) of perceived newer technology in construction and efficiency........and certainly closer tolerances than the body parts of our 928. I think we can live with that. Great effort, as always, Hans.
