Mando,
those TB's look about 48mm, or so. Have you got an air filter strategy?
As you probably know, I have the vertical version (
8 Pack) and use Velocity Stacks for the track and fliters for the street. I am still scratching my head about how to get the stacks on inside filters.
I have had no luck with socks as the roll on the stacks does not allow a spring to fit without disturbing the airflow.
Can't wait to line up against your beastie.
