1/26
I recently purchased a ATI Damper only to discover that the drive pulley hub
that comes with it is appro. 3-5/8" diameter at outer lip vs. the Alloy thin
belt damper/pulley's appro. 5-1/8" diameter (stock pulley was appro. 5-1/2").
The thin belt water pump pulley is appro. 4" at outer vs stock's appro. 4-1/8,
so no diff. there. The thin belt alternator pulley is appro. 2-3/4" outer, vs
stock generator's 3-1/4". Since output is apples to oranges between alternator
and generator am wondering if there is a consensus on what speeds the
alternators should run at---am using a Delco 63 amp unit. Am also wondering if
the slower speed that the water pump will run at will be a problem as I am
going to be using the six vein aftermarket pump in alloy housing and running an
12" electric fan. Thoughts? Suggestions? Other's experiences?
Thanks, Dan
