[QUOTE="Catmonkey, post: 15550022, member: 124025"] Yes and no. There comes a point of diminishing returns when big is big enough and larger won't gain you much. Not to mention camshaft selection is going to dictate just how much air the engine can use. Same goes for how much boost you can run. But realize the bigger the throttle body, the more it's going to fell like an on off switch. The throttle body reacts in terms of angles. With the large throttle bodies, you could be flowing as much air at a 45* opening as the stock throttle body at 90*. Now that's a consideration, for me anyway, on the street. On the track it doesn't make a whole lot of difference. It sort of depends how you use your car and how finicky you want it to be. I've had my share of temperamental rides in my lifetime. A lot of people contend it's in the tune. Sure, you can tune some of it out, but look at my comment at angles, the motor reaction is linear. Here's a pic of my supercharger inlet ported for the big Whipple eliptical. Is it overkill? Absolutely! My street TB is the 72mm twin. When I go mile racing, I can swap out the twin for the eliptical. The adapter plate is the same dimension as the throttle opening in the throttle body. Certainly something a little smaller would probably make as much power, but the eliptical curvature won't move quite as much air at lower speeds (angles) as the conventional monoblade shape of the same size.
