DTM Cooling or 911 type?, any improvement? Options

[RFoulds]

Since I live in the desert, and I am keeping the a/c for my latest project, I am researching Raby's DTM (down the middle) cooling and FAT Performance's 911 type fan conversion and shroud. The car is already dual carbs so I dont have to worry about clearance over the FI intake tubes.
But, I will also be running a small compressor for the a/c.

Initial search tells me the 911 style looks great but doesnt cool any better, and the fit is questionable.

DTM should be better cooling, and reviews of the kit for Type 1 or type IV converted Beetles is really good.

anyone ever do one of these options in a 914??

I've used a bunch and I made my shroud for my '67 bug, which is a custom made all steel DTM/Joe Cali hybrid.

For the 914 it's a custom made DTM with no cooler outlet, as this outlet interferes with the engine lid. You then have to plumb an external cooler, not included.
I don't know if these are still being sold, as the stock cooling system is still the best choice for most apps.

The 911 fan, you have to be careful as some like the FAT set up is also too tall for the 914 engine bay. They didn't cool overly well because they push too much air and the shroud doesn't fit tight enough to the fins, the air is pushed over the engine instead of being rammed through the fins. Also like the 914 DTM there's no provision for the oil cooler, so you have to run a external oil cooler set-up, again not included.
If you could find a Sharpbuilt T4, 911 fan shroud that would likely be a better solution as it has accommodations for the stock oil cooler.
