Darin,this one's kinda context related.For ram-air it's hard to beat the forward stagnation point of the car.In NASCAR,where your drafting behind another car,you lose this ability,so the cowl area becomes the first runner-up.Not as much pressure,but some pressure,even when drafting,and it's further from the track surface and likely lower temp for better charge-density in engine.----------Cowl -induction was introduced in production Chrysler cars in the 1960s which were also racing NASCAR.It probably wasn't as "good" as front harvesting of air,but was very sexy and loaded for testoserone-packed car sales on Monday after the races on Sunday.--------------- The thing I did at Bonneville was strictly an attempt at drag reduction,and you can tell from the numbers that Honda had done a pretty good job with the CRX.
