I think the problem with the 80mm BBK is that despite its larger diameter, the diameter of the intake is smaller than 80mm, therefore you won't have a clean passage for the air to flow through.

port your stocker. if you have the patience, you can do a really nice job yourself. take a dremel with a nice conical shaped rounded cutting bit, a few sanding wheels for the dremel, a few sheets of different grit sand paper, and you'll be good to go. putty-form jbweld works really well

Unless you are using an aftermarket mass air body a larger throttle body will do little if anything. The stock mass air body has an equivalent flow diameter of a 66 mm bore.

You do not mash your pedal all the way to the floor off the line. If you do, you obviously don't know what you're doing. As the engine speeds up, your foot should get heavier. Obviously quick-like, but that's how you work the throttle. No matter what you're on, track, or street. @ ALL throttle positions, a larger unit would be an advantage, period.
Even on a factory intake. Anything over 80mm may be useless there, but it's definitely better than 75mm.

Thats the first i've heard of this technique. I assume you are alot faster than 12's. But for us slower cars... full thorttle all the time works best at the track.
