I recall seeing pics of them dressed in olive drab paint...

Howitzer? The canon? Never heard of them running TIV, well in any case that is not VW, is it?
Corvair seems to be the main commercial car with similar type cooling.
I simply like the open layout and looks. With CF shroud it really is stunning.
Cooling capacity works good too without any extra needs of directing fins.

This Horizontal fan conversion was used on a FH (70mm Field Howitzer)-a Type lV propelled cannon used by many NATO army's. This info was provided by a gentleman
from the Netherlands. All I was told by Ahnendorp when I bought this one, that it was made for the Military.

It was made by Riechert Tuning, the head covers are very thin fiberglass, and do not have
the ducting outlets for the heater boxes for heat, like the earlier versions, and OD green is a Military color



Here is a pic of the earlier version, the head covers are 3 to 4 times thicker fiberglass than the Military version, and these have the heating vents, just blocked off.



I picked these up, cause I believe they provide a more even cooling & higher cooling capacity, for one reason, but the most important is they will be easy to modify to accommodate
a much wider motor, anywhere's from .500"-12.7mm to 1.0"-25.4mm per side.

I'm still trying to figure out how to get Richard to make some molds off them, I think a cut down Corvair fan would work out ~ perfect in the middle of those, with a ~flat circular plate in the middle, perhaps w/a nice inlet.

Probably could be much lower profile as well, and the air doesn't have to make the 90 degree bend by itself-- the fan does it. (Almost weightless fan at ~9 inch size, thin magnesium, but the alt has to go somewhere else, not under the fan)

IIRC the side bits are separate?
(Thus easy to make wider)

Just a thought---
The Corvair used one (later 2, one each side) bellows assy. very similar to what VW used for the thermostat... GM simply dumped air pressure from the cooling plenum with it when the thermostat(s) were active via a linkage and a hinged door.

Yes the head covers are seperate, so yes it would be very easy to make spacers to move the head covers out. All that would be needed is a spacer to match the spacer thickness under the cyl's.

I don't think that there is any other cooling set up that could be so easely modified for a wider motor.

Sorry blitzvw, I believe that this was the very last NOS that Ahnendorp had. And I had the chance to buy 2 from Ahnendorp, but passed on one, but changed my mind and went back but it was gone. I had found it on the German Ebay.

From what I understand Ahnendorp had the military contract to have the military version made, and had Riechert make a large # of them, and mine was one of the ones that was left over.

There are still used setups out there, I found one & Wally had found one, and the timing wasn't that far apart, but the locations were he found his in Europe And I found mine here in the US, and don't let me find any more before you do... ...
NO just kidding, I have what I need, one for a Turbo motor and the other for a really big stroker, which would be about 2.0"-50.8mm wider than stock width motor...

Hey Wally I don't see why it wouldn't work on a Pauter motor...

This pic really turned me on. Sorry "owner" I do not remember who you are. UK somewhere I believe.

Pulleys from the local hardware store, double roller bearings, 10mm marine grade aluminium plate, spacer for the pulley, bracket for the pulleys.
Cylinder shrouds will be aluminium with directing veins which helps reducing temps again... I know the date...kids slow every project down...

At the moment the 914 2 liter stock engine will be used to fit everything and so I can drive a little sooner. Good thing I test fitted the EFI parts as I needed to mod some parts...
The larger riechert pulley has gotten an even larger toothed ring (never thought it needed to pass the ds-pump
So the pump cover was clearenced:


This is the status at the moment:

Test fitting intercooler and some of the ducts (plenty more to follow)
