for my 968, how bout we start with new ps pumps, lines, oil cooler lines, and radiators that say something other than "Porsche" on them to run after the current residents living inside my engine bay quit ? And btw, next time my AC fails, is an AC delete a complicated matter ? No use hauling around dead weight that I'm not keen to replace.

Todd, go check out Groves Aircraft Supply or DeComp( in Tulsa ) web sites. Think the deal for a one- of or low run would be carbon fiber with vacuum resin deposition. I think one of them sells a starter kit for less than $1k. You still have to make a mold but can be very creative. They also have release film etc. If someone REALLY, REALLY wants to try this I’ll send you some free bagging material (heck, I’ll make you a bag and kick in a vacuum puck along with some yellow seal tape for the end). You need a hose and a pump that can pull down to like .5mb or so, probably an AC service pump would do. For small parts you can use the kitchen oven with a digital temp gauge. I made a test oven here for samples and R&D stuff with a cooking range bought at Best Buy. The production oven is a walk in gas fired affair you can drive a car in so a little cheaper when just playing around to say the least. If someone has some expertise and wants to do this I might score some free carbon fiber from one of those guys too. We can talk.(Did I mention I need some carbon fiber intercooler tubes for my 951 while you are at it? )

Great info and offer Goal, but I'm more an idea guy and less into production. lol
How about a two piece sheet metal press?

My problem too Todd. Time. I was thinking on the intercooler tubes making out of something that would be solvent based so once formed could disolve the male form. Except for the heat of the cooking process styrofoam would be nice. Same for manifold. However that won't work. Maybe plaster then break it out. ( or sand with a solvent based binder? Like in a sand casting internal) Still thinking and might actually try it some day....

Goal:
I tried PVC several years back for the IC pipes and they were ok, except where the band clamps were on the ends of the pipe and the heat and pressure caused the ends to deform.

An injection water cooled mould for an intake would be $43,755.00.
Mould would take 8 days from design to machining. Fitment prototypes 2 days after, finish product in 2weeks fromt that point.
Mould would yield approx 2300-3000 units before compromise. Lower yield equals higher/repititive production. Higher yield equals slower daily production.

From the conversations I have had with some reputable builders on this board, not much. Maybe 4-7%.
The stock intake is not bad at all for most applications, including modified. Maybe not the strokers and 16v's, but for what 98% of people are doing they are more than accpetable.

90 @ 500
180 @ 250
360 @ 125
So there is your break even analysis.
If lighter, better/more even flow, etc. I think 200-250 would be a done deal for most 951 owners.
Ideally would be to mold one that can fit 944,S,S2 and 951, if possible.
But even if only 951, if a small % of worldwide 951 owners ordered one.... ????? $$$$$$

generaly speaking the best way to make any performance product oem or stealthy looking is to make it from black plastic . I'm realy suprised china is no all over this..high flow plastic airbox's plastic inlet manifolds for various cars plastic shelled liquid intercoolers.
I guess its more about bling for many ..
