[QUOTE="iismet, post: 15392328, member: 15250"] I was looking at => a1 v1 p1 = a2 v2 p2 and by reducing the inlet area we could increase the velocity while maintaining the pressure. I have no idea what the pressure is, but my car stays cool while running up to 135. => solving for a2 => a1 v1 p1 /v2 p2 Since we want the pressure to remain constant p1 and p2 cancel each other out leaving a2 = a1 v1 / v2 So v1 = 135 a1 = factory inlet area v2 = 160 (170, 180 etc) I was thinking of fabricating contoured blocking panels which could be drilled to provide the appropriate a2. Take it to the track and run the crap out of it paying attention to h20 temp. Tape and or drill as needed. Pegasus sells different density wire mesh that may work. This would move the air around and over as opposed to the bottom. I am not this far along. Top speed on the 3 tracks we run is around 135. It may be possible to get more at The Ridge, but I don't have enough experience there to know how much speed I can carry into turn 1. Should I run into lifting issues this is a path I plan to pursue.
