underdrive belts

[broncos97]

I recently bought an unorthodox underdrive pulley off a buddy and i was wondering if anyone had either the drive belt part #'s or length specs. ka24de with a/c and power steering still. let me know if you guys can help. thanks.

alright all i'm seeing is stock parts on there lazy. the underdrive pulleys are smaller to help with parasitic draw so the belts are smaller. I'm sure some of yall have dealt with this before. thanks for the help

Just go one belt size bigger. And if thats wrong, not likely, change it for a bigger one. Duh!

I had the ASP racing pulley. Best thing evarrrr!

PS. Its not that the pulleys are smaller, they're made of aluminum, and weigh dramatically less, so they take less force to fully spin. They lose rotational weight which is where that parasitic loss is. one pound may seem small and meek, but rotational weight makes more dramatic differences than regular dead weight loss.

PPS. Before anyone mentions so without facts, these motors are internally balanced, so these cranks won't FUBAR the engines.

When u put the belt on and they're loose that means u go with a smaller belt... underdrive not overdrive. read previous posts please...
