High speed stability issues

It was bad. The jersey barriers were flying by and close . I do believe that the scoop is pling the hood up as I have developed a crack at the peak of my glass hood. I have picked up a steel factory hood. I think a cowel scoop makes sense. I asked Harwood about an open rear scoop. They told me I can drill holes in the back of the scoop to let air pass through. That's a cheaper option! Just not sure if it'll do anything. I may try to do some sort of pan underneath. It'll be tough to fabricate and mount. Hoe about lifting the rear of the hood or punching vents in the rear?
