We ran into Justin Starkey of VMP Tuning (www.vmptuning.com) at AETC '09, and he shared with us VMP's new-design Big Bore inlet elbow for Shelby GT500s with stock or TVS blowers, plus GTs with Roush P51 superchargers. The new inlet facilitates mounting a dual-bore, 72mm throttle body (or a large monoblade piece) onto its face using the OEM bolt pattern, and eliminates any need for port matching the throttle body or inlet. Notice how the inlet opening has been reformatted into a D-shape. Justin says this maximizes and improves airflow by opening up the inlet of the blower, and using a throttle body that will take advantage of the flow capabilities of the new inlet.
