Porsche Fan Conversion on Type 1

[Andy]

Preheater sounds a good idea...

Covering the oil cooler is not going to help, as the oil only flows through the cooler at 180.

Just want to do what I can to try and minimise the wear at start up, when oil is cold.

Have thought about putting a baby bottle warmer on the oil filter for about 10 mins after start up. Not sure about that though.
The Porsche Fan seems very efficient, I am running 9.5:1 and an 88 mm crank, and I hardly ever see the temp rise above 180.
