[Tigers] Reduced diameter water pump pulley

[michael king]

As you said if the radiator is up to the job its more about air flow.. and
if you block the horn holes and have a good flex fan.. that's probably
enough.. or a 10" electric pusher fan that comes on as temps rise. The
enclosed shroud and cross member gap will also help.

The cars are generally good on the run.. more an air flow issue at idle..
and the reduced pulley is "a" solution.. but certainly not "the" solution.

i find with my fluidyne radiator, 10" pusher and horn holes blocked my car
is fine in traffic even on 40+ days...and i dont run the shroud.  that
said.. the carb certainly gets hot. but that's another issue....
