Heads up runs in Stock & Super Stock

These are what I found TPI Intakes and runners

The following airflow tests were performed on the University of Northwestern Ohio's SuperFlow SF600 Flow Bench.
All CFM values are corrected for airflow at 28 inches of water.
Injector flow rates are flowed at 43.5 PSI on an injector flow bench using test fluid with same density as gasoline.
