Found a BBK 75MM locally for cheap. Compared to the stock TB:
The orifice:
An aerial view: (really brings out the difference in the throttle blade)
I threw it on. Looks at home:

I haven't driven it around yet or anything because it's currently on jack stands right now. I'm right in the middle of installing some rear lower control arms. They had the wider 99-04 sleeves pressed in them so I had to order a special 12in long 9/16 drill bit to drill out the control arm mounting holes. I might have some pictures of that later this week.
Well, I watched a video on YouTube posted by BBK where they take a stock 5.0 SN95 and install a 70mm throttle body and cold air intake. Their "completely stock" test car gains 24hp and 20 ft. lbs. of torque. This was through an automatic transmission.
Is this totally bogus or is it legit?
Or does the SN95's Upper Intake shape contribute to such a large gain compared to a Fox style upper?
Maybe they bumped the timing down on the initial run, then bumped it up on the modified run, therefore inflating the numbers?
Any thoughts on this dyno graph or BBK's claims?
Kinda seems like a very generous gain for just those two mods.
