Default Vortech Serp belt swap 3.33 to 3.12 pulley

hi,

i was just curious.. will the supplied 79.5" serp belt that comes with the non-rev vortech kit.. work with the a 3.12 pulley..?

or do you have to change the belt too to accamodate for the smaller pulley..?

if so.. what serp belt ( brand/size) are people using.. when upgrading to the 3.12 pulley..

for a stock belt layout.. no pulley mods, or timrods layout..


much appreciated in advance..

thanks
Tony..

Yes it will work as long as you still have enough adjustment in your pully. When I switched to the 3.12 pully I just got a new belt though bcause mine was pretty narly looking, dont remember what size, just went to the Autozone and got a Gates belt that was 78" i think...

you drop 1/2" in belt size for each 1/4" decrease in pulley size

in the end its easiest to buy 3 or 4 belts around that size, use the one that is the tightest and return the rest.
