Belt measuring help

[muscleatsrice]

What’s up SVT P. Does anyone have any good tips on how to measure for correct belt length? I’m replacing the 3 blower idler pulleys(will be running all 100mm, no snub idler) while keeping the stock upper blower pulley for now. My stock idler bearings are beginning to wear. Thanks in advance.

Pretty sure there’s a thread with a ton of pulley and idler combos with belt lengths.

Otherwise putting a string around em and then measure is about all you can do

String is your best bet. Then buy a few belts right around what size you measured. Save yourself some aggravation and just buy a few different sizes. 3-4 trips back to the parts store gets old.

Thank you everyone for the replies. I’ll give it a shot.

I keep an old cut belt in my shop for this reason, just keep tensioner travel in mind when measuring.
