What sort of shroud is he running? I spent about 8 hours reading a Samba thread that Jake, Clark, (Volkaholic) and several other luminaries participated in. Two main points I got before I bought my replica Thing shroud:

  • Engines under 2L shouldn't require any external cooling
  • 90% of aftermarket shrouds are crap. They don't have the correct internal baffling to properly cool the engine. 

In testing Jake did, the only thing that came close to his DTM setup was the Thing* shroud. I don't have specific temps, but my 2L motor used to get right up to the red line on the temp gauge pulling grades or long freeway runs at 4,000 rpm.  Installing a Thing Shroud and TypeIV oil cooler solved that. I can run flat out all day and my temp gauge never gets past 12 o'clock high. 

 

*According to someone who posted in that thread, because of the low speed, low RPMs VW expected Things to run off road, theyre-engineered the shroud and it's the most efficient one they ever made.  And supposedly all Brazilian and Mexican VWs used it from them on. I bought mine from a Canadian company, but AAPiston sells them now, with and without heater holes.
