- 2015 GT A6 3.55 Gears ..
On my ho kit I went to a 3.50 from the stock 3.70 and made a big change in power ..I now have changed to a 3.40 from the 3.50 and made zero difference in my ETs and MPH at the track ..So a pulley change of that small size ( 3.50 to 3.40 ) was a total waste of time ..So really for you to feel a change in power you would need to go from a 4.75 to a 4.50 .. What most people don't get is when you pulley down your boost comes on earlier and that is great fun and helpful for drag racing ..
