[Tigers] Reduced diameter water pump pulley

[FHSLOTH13 at aol.com]

I blocked the horn holes, had the radiator cleaned, added a smaller water  
pump pulley and a 13" flex fan.
My stock MKI went from running 215 F to running 190 F on hot days in  
traffic.
 
I did all this for about $75. Well worth the time, money and effort since  
the cabin temperature decreased as well by approximately the same amount.

Hi  Owain, 


I see Michael has already posted the main part of the  answer. I would just 
add that there were positive results from such a change  in the in-depth 
cooling study a few years ago that is posted on the TE/AE  website. 
http://teae.org/cooling-the-tiger/ Somewhere deep in the study they  report positive 
results with conclusions similar to Michael's.  


Anecdotely speaking, I would say my Fairmont pulley has been  helpful. I 
have heard others who have used it report similar favorable  results. That, 
along with running the engine distributor vacuum advance off  manifold vacuum 
instead of ported vacuum and a six bladed fan have been  especially helpful 
for me with the idle and low speed cooling. And that was  after putting in a 
recored radiator.

Hi Gene, 


What's the motivation?  I could understand _increased_ diameter for high 
revving engines, but why  smaller? More water flow is unlikely to aid cooling 
and could make it worse.  Recirculating airflow is the only issue I've 
encountered with tiger cooling  whatever the engine or climate if the radiator 
works properly.
