Looks like your setup is pretty awesome. Have you raced anything good. The only thing that I would suggest is positioning your bottle a different way. Since its sideways, the siphon in the bottle won't get all of the nitrous when you're accelerating. But since we're only running smaller shots, it doesn't matter as much anyways.
Great job setting it up.
BTW, did you run your line to your bottle under the car, or how did you get it to the trunk? Any drilling involved?
