Default Re: Factory Pro Velocity stacks

They're from Factory Pro in the US: http://www.factorypro.com/Prod_Pages...650,03-12.html

According to Factory Pro the 35mm & 70mm stack combination in Tapemonkey's pics give a power & torque boost (about 3bhp / 3ft-lb) in the mid-range, and a small increase at the top end without losing anything elsewhere.

There's a thread on SVRider at the moment about using the stock Suzuki stacks from the Gladius in the SV airbox. They fit straight in (ideally the holes in the SV airbox should be widened by a couple of mm but it's not essential).

I've got some curved Suzuki stacks from a 2010 V-Strom on the way to me and I'll be posting about them when I've got them fitted (hopefully this weekend). Only cost me £20 so worth having a play with.

In general, longer stacks are supposed to be better for mid-range (in the 4,000 - 7,000 rpm region) while shorter stacks are best for top-end power. The V-Strom stacks are about 75mm in length.
