Here you guys go. We were able to get solid numbers (before/after) today.
The baseline was done on a stock car with the charcoal filters removed. Adding the scoops gave us 5.5whp while adding the filters netted us another 2.7whp to give us an 8.2whp gain. This is with no ECU relearn and reflash. The gains should be more significant as the ecu learns.
