Default PULLEY SIZE

i was wondering just how small of a pulley can be installed before you reach the ends of the mechanical limits of the M62??
i run a 2" right now with no knock but ive never heard of anybody even remotely close to running any thing smaller

Have i reached the limits of the Series 1 L67??

You're over the limits. And I've run a 2". It'* self-defeating because of the amount of heat it makes.

I'm surprised you were able to do that w/o knock. Can you please list your other mods out for us.

Thanks

Thanks Squirrelly...while the sig is a great start, I wanted to make sure nothing new has changed. Frequently we forget to update our sigs.
