Factory air box with intake support,
The big problem is the blower heating intake air.
Just as I chicken lift going into 1 it is 194 mph and a little over 150 under the bridge, really stout acceleration for a non turbo car. I also have AP rotors, Carbotech pads and spring rates roughly 2 times higher than stock.

I am surprised that your factory airbox is sufficient to flow enough air to support that kind of boost & power. I just put a 4.0L Whipple on my GT, and have been figuring out how to have my local fabricator make a better intake setup, similar to the GT Guys, only better. So many people have said that the factory airbox is a major power limiter once you go Whipple. People have told me that they picked up anywhere from 2-4 psi of boost just by either drilling holes in the bottom of their airbox, or going with a dual-conical filter/dual snorkel type setup.
