60mm/2.25" cooling duct?

Hi,

got a Porsche 944 that should have an alternator cooling duct, but it
was lost by one of the previous owners. I have scavenged all the pieces
except for a short length of flexible duct, it's 60mm in diameter but
2.25" would probably work. A quick look at some racer's supply sites
show that this stuff is generally only available in 2" or 2.5" diameter,
can anyone think of an underhood application that would use a 60mm air
duct hose? Trying to avoid Porsche dealer, not only is it very far away
but prices are often shocking.

thanks,

nate

How about flexible exhaust piping or heater duct from a ... um... volkswagon?
This site lists: TYPE 3, 63mm X 1000mm, EACH $4.95

Good call, Paul! Volkswagon: the people's Porsche.

Nice! I like it! (and VW parts are a lot cheaper than Porsche
parts...) I actually thought of something like that, but I didn't know
where to begin looking.

Now if I could just get someone to verify what model VW the CV joints
originated on... (the boots have a 411 part number, but my ETKA coughs
when I try to look up the vintage stuff. I was hoping to confirm that
it's the same as a 90mm inner CV as used on the early watercooled stuff
but no joy...)

I see the beginnings of a book - "the frugal Porschephile, or how to
drive a sports car on a people's car budget"

I used to have several VW bugs when I was a teenager.
Turned one of them into a dune buggy with mostly 411 parts.
Dynoed at 180 hp at the wheels. Had problems keeping transmissions
together though. Had a 356B once but it was all rusted out and I
junked it. The 914 slid into a light pole sideways at 20-30 mph.
And I junked it.

Try Aircraft Spruce or Waco(sp?) look for aircraft heater hose.
I use some on my IC to throttlebody with good results. I would be
surprised if they didn't offer 2.250" size. Firberglass, rubber
covered, wire reinforced and good for well over 1 bar boost pressure.

Actually Aircraft Spruce was the first web site I hit...
