The amount an engine will suck air is dependent upon:
1. Diameter at butterfly
2. Intake tract diameter and configuration
3. Porting of heads for flow (both intake and exhaust)
4. Size of valves
5. Characteristics of combustion chamber
6. Cam profile
7. Cam timing
8. Stroke
9. Bore
10. Exhaust system diameter and configuration
Study up on volumetric effeciency of engines.
Uhhhh...... putting a bigger hole in the initial intake prolly won't do much except empty your wallet. The money they want for this monstrosity is better spent on driving lessons or suspension upgrades - far more bang for the buck. It goes along with the "billet" injector rails.
