I run a regular side mount ProCharger and am upgrading to a PROCHARGER AF006A-019 Bell Mouth.

Any recommendation on a efficient screen cover?

I am concerned about rocks and stuff flying off the tires and into the inlet.

Best people to ask is ProCharger!

I personally don't run a screen. I talked to Danny Nelson awhile back, and he sold one of his 6.10 cars to a guy that put a screen on it, and the car wouldn't run better than 6.30. Once Danny saw the screen, they pulled it off and it went right back to 6.10.

So if you do it, make sure your not restricting the inlet.
