I hope Melkman chimes in on this one, because I'd like to know if this is right... but I don't think the Works stacks are far from the stock ones. Like the previous poster said, they are both variable, and move based on throttle. They both do the same thing essentially.There's a decent amount to be gained with the works velocity stacks. The works stacks are a strictly crafted race part for the r6. These stack stack vary in length 2 shorts in the middle n 2 longer ones on the outsides.
NOT what OP is referring to....Google is your friend.
There was a post on here that graves claims a STUPID amount of power with their insanely expensive stacks. Nobody has dyno proof. Nobody runs them. You're gonna be hard pressed to find any good info or results. And I'm sure you'd give up the 5 HP mid range the variable stacks offer over the 06-07 stack setup.It's not the same install as the factory pro staks for the older r6, kinda the same as the yec setup for 2010+.
And yes the variables move up and down by the stock stacks are all 1 size. The works stack are different sizes and move up and down.
Post pics! Then dyno results too please!!!Well the stacks are installed, just have 1 issue so far. The rubber bottoms in the short stacks in the middle doesn't go down all the way and the short stacks hit first before the larger stacks make a seal.
And yes I'm install adjustable sprockets and Manuel cam tensioner have them timed and dynoed by orient express
