Quote: When you seal the scoop if the car does not pick up,the scoop is the problem. Most of the time being the scoop opening is not large enough,also some scoops just will not work on some cars. You may also need to go up on your jet size a few steps. The extra air can cause it to lean out.This will most likely be your problem than the scoop opening being to small.
No factory type scoops work for ram air. The opening has to be in the boundry layer which is a few inches higher than the factory scoop opening. As the car moves forward the front of the vehicle diverts air up and over the scoop and very little into it.
