Last I had heard and read, A wind/smoke test was done on the barracuda sport hood. And results showed with the design of the hood, the smoke went right up over the scoops and wasn't good for ram air. I can't remember all the details, but the only thing it helped with was letting heat out when parked. Something about the wind hitting the windshield caused the scoops to be air deficient since they were too low. The challenger scoops were up higher and did show an improvement. You may not want to cut up your hood. Goodies set up he has done seems it would work with better results if made propper for flow and release of extra air
