Belt size question.... 4 lb lower guys in here please

[1slosnake]

Hey guys I plan on putting on my 4 lb lower tommorrow and need to know which belt size to get. I have a Steeda 2.80 pulley with a 90mm idler. I was wondering if somebody was running the same combo and which belt did you use. Any help would be appreciated thanks in advance :coolman:

i was using a 77.5 with a 2.93 upper and 4 lb lower..so you more than likely will need a 77" belt or maybe a 76.3/4 hope this helps..

Actually the 77 5/8's did the job. The 77 was to snug and didn't want to go over the snout :shrug: But everything is all kosher now. I will get it on the dyno sometime this week to get some numbers out of the old girl. :coolman:
