The Bergmann 911 style shrouds look really cool, but are expensive, do not distribute air evenly over all the cylinders (iIrc the fronts get significantly more air than the back), it's not designed for the thermostat flaps and an exterior oil cooler is the only option. DO NOT SPEND YOUR HARD EARNED MONEY ON ONE!
Al, thanks for the quick reply. You are the king of acronyms BTW.
I would've figured with all that air from the jet-engine turbine, cooling would've been a mute point.
My cash is hard-earned so I will take your advise seriously.
Will, there's a thread on the Samba where a guy takes (I believe) a Bergmann shroud (and after studying a 911 unit), builds some interior diverters, and after some trial and error, gets much more balanced cooling out of it. IIrc there was work to balance it from side to side as well as front to back.
Here's some reading if you're bored-

And thanks for the compliment; my 16 year old son might disagree with you though...
I've seen some reviews looking at cooling efficacy, and I understand that they're quite bad. The standard doghouse shroud works better, from what I recall. I wish I could locate the article I read about this.
Pat: can you chime in on this?

The first time I owned my IM I put on a BB 911 styled shroud. I never had any cooling problems, but I also didn't have a CHT gauge, so who knows.
It looked really, really nice, but was a bit of a pain to install and I had to cut away some of the engine hood's fiberglass to clear the unit.
With my new engine I went with a stock VW shroud with flaps.
If you want something else besides stock go with a Jake Raby shroud, which is proven to cool properly (but can't be used with heater boxes).

Will also consider that turning that big Porsche fan eats up more hp (sorry, how much I know not) than the type 1 fan.
PS- more reading for when you're bored-
My car came with one. I just put a temp gauge on # 3 and have not seen it go over 362*, oil 190* slight up hill. Drop a gear and bring the rpms up and the temp starts to drop.
I am satisfied!

There's no arguing with the fact that they look bad ass.
