i hear the v1 is alot better because of belt issues. anything else?

 

Nothing to do with the Vortech blower itself...supposedly the change in brackets offered by Stillen with the kit... Internally, minor changes like higher multiplier (more boost) and helical cut gears (less noise) in the V2.

 

so a v1 bracket matched with v2 blower would be the best? the v1 bracket is better..
