Repro of the Judson air scoop for Karmann Ghia

[dmercer]

Hullo folks,

I recently did a write up of a reproduction of the Judson air scoop for the Karmann Ghia. If you are interested, you can find it along with images at the following URL:

Best,

Great report Dan...it's always good to have a first hand report on something like this...especially when this repro was being sold with pictures that didn't show enough detail.

Human nature being what it is every seller will want to show their product in a good light so you rarely get pictures showing any shortcomings.

The original Judson Scoops were certainly of a better quality but I'd imagine with a bit of elbow grease you should be able to iron out a few of the repro imperfections.

The problem with having a batch of these scoops repoped is that you need to throw an large amount of cash at the project without having a good idea of how many you'll be able to sell.

We have a member who has offered to repop these in fiberglass but I've resisted as some will resist fibreglass in favour of a cast repop or an original...it's a bit of a conundrum.

So how much was that original one I sold too cheap worth when I sold it too cheap in 93?

And for more abuse... how much would it have been worth in today's market?

[DaveM]

two or so years ago, 150-200 was the going price for an original.

Thanks Dave... I knew when posted about abuse I could count on someone like you to chime in!

When you consider the Judson Gauge is more readily available but carries a higher price, current prices for scoops aren't THAT bad. Recent price around the $300 mark.

The problem with buying an original scoop is that there aren't enough to go around.

Strange really...rarer than a Judson Gauge but sells for less. I suppose the reason for this is that there are less people bidding on Scoops.

Most people who come to me looking for an OG Scoop usually find one in a year or so. So a small market would exist for a cheap fibreglass repop to use while they look for an OG version.

Perhaps we could use Dan's alloy repop to make a really cheap fibreglass repop. My brain hurts

John, wasn't someone working on a scheme to re-work a Judson so that it could fit in a Ghia without the need for a scoop? As I recall their solution was rather simple and the results looked original and not hacked.

Any progress on that front?

[John Moxon]

I'd buy a repop. Sure would be better than the stand-off kit I fabbed.

[John Moxon]

The modified manifold idea is what I remember reading about on your website. That would be a much better solution than the scoop for ghias.

I love Judsons, but it would take a lot to make me butcher a decklid to make one fit.

[DaveM]

[dmercer]

Clearly I'm not adverse to modifying a (plentiful) deck lid in a period manner, however for the record, the deck lid original to my '58 is not being cut. I have a second one salvaged off a '58 rear clip that has some dings and moderate rust that will run with the Judson once it is all straightened out.

I agree that MAG superchargers are cool, though evidentally they don't provide as much boost as a vein based blower like the Judson. For those who are interested, check out the following links with info on MAG:

It may go without saying, but finding a complete, usable MAG kit makes obtaining an early Okrasa setup look easy. Some folks, like DaveM are lucky enough to do both. ;-)

Been exchanging emails with a couple of Judson Ghia owners and it seems most don't have any problems sourcing a spare decklid or making an original, bona fide, period modification. They did however think twice about cutting the original Judson Scoop Template

It also appears you would need to take over 2 inches out of the height of the stock manifold to accomodate the Judson Aircleaner and from what I can see that would not be an easy proposition.

Certainly not a straight-forward cut and shut.

Hi does anybody know how you can see
the diffrens between an org and repro scoop?

[coolairX2]

The surface seems just a touch rougher than an original and the letters are not as crisp. Other than that its a great repro and would fool 99 people out of 100 once painted and on the car.
