Took the speedster out today for nice run. Outside temp was 75*. Oil temp climbed to 220* but CHT was only at 280*. I have an external oil cooler mounted under the driver side read seat. It kicks in at 180*. The engine bay is all sealed up.
I am thinking about getting the DTM shroud, welded fan and smaller 356 alternator pulley to speed up the fan.
Any other thoughts or ideas?
Bobby, do you have a Type I or IV engine? Like Stan said, a DTM is a pretty expensive solution. When faced with overheating issues I went another route.
According to some info Jake Raby posted in The Samba, the only shroud he tested that even came close to a DTM was the original Thing shroud, which was re-engineered because VW assumed that Things driven off road would be going slower at high rpms. It was a close second to the DTM.
The good news, a company called Cooled1 makes a repro, and sells a kit that includes the shroud and a larger Type IV oil cooler. I bought mine from them, along with the bigger fan, but IIRC, someone in the states sells them now. (AA Piston??) All in I think it was ~$550, including shipping from Canada and import duty.
Problem Jake reported is that a lot of cheap aftermarket shrouds have bogus, or worse, missing, internal baffles. Which, I believe, is why Carey asked if you had a chrome one. They’re the worst. The one I replaced had 1.
More than you ever wanted to know about shrouds.
