[VB] redux: Porsche Pulley

[C. Dreike]

Hi,
Ran an experiment on my upright engine. Last weekend I motored down 
and back up the freeway at WOT using the stock pulley on my 
alternator. Today I ran once again however with a Porsche pulley. 
Slightly smaller diameter, have not yet made an estimation of how much 
smaller. Ambient air temperature was about 70F on both runs. With 
stock pulley I saw CHT at about 365F and still slightly rising. Today 
with the Porsche pulley I saw a max of about 345F. I hit 75mph before 
I let up on the throttle.  I think I'll keep the Porsche unit in 
place.

BTW, the stock belt is 905mm. I went to a 890 for the PP.

Cheers!
