OK, so shook the stupidity off(for now). Removed TF and compared measurements to oem 69 340 balancer. Extremely close in measurements, or at least the ones that matter. Timing marks in "wrong" spot for my application, so did the math and came up with 0.06" per degree. I've seen 0.04", which is wrong for my application. On my build I've discovered a few "specs" now that are NOT absolutes.
Circumference = pi×diameter
3.14x7"
=21.98" ÷360*
= 0.061" per degree. I verified this by checking the TF markings already on balancer. Set balancer in bucket of hot water to help install and used the rope trick coming up on compression to get 135 lb/ft.
Thanks for the help folks. :thumbsup:
**Edit**, I forgot to add I also gave it a couple coats of clear before install.
Thanks for heads up from a few members that while the balance looks nice, it's cheaply painted and not durable.
Oh also the weight difference is substantial, TF=5kg, and oem= 3.2kg.
