Ran across a reference to a new Blue Thunder Thunderbolt head coming out, and details out yet? I keep swinging back and forth on my next build and this time I am going to set a plan first LOL. I am thinking it will probably be a big medium riser. They already have a small port medium riser, tall port and tunnel port. The tall and tunnel are probably big for anything but a drag car, so I would be looking for something in between a standard med port and a high riser.
