HOT ROD Magazine Camaro and Misc.aero @ Bonneville

I spent some time digging through HOT ROD Mag..
In the Feb. 2008 issue they did a piece on their Camaro.Here are some interesting tidbits:
* full depth front airdam
* the car is lowered
* nose is completely sealed
* mirror delete
* wiper delete
* full aluminum bellypan
* extended rear spoiler

With the supercharged engine and 1,178 Bhp the car's top speed is 249.832 mph.

With a single 4-bbl Holley Dominator,normally-aspirated,and 175hp shot of NOS,developing only 925-950 Bhp,but with a Pro Stock hoodscoop,top speed is 261.602 mph.
A close inspection of the supercharger suggests that airflow would separate at : * driven pulley
*idler pulley
*blower front plate
*throttle shaft/accelerator-pump pivot plates
*carb body
*float bowls
*air cleaner body
*"accordian" filter element
*blower explosion-proofing buttresses

Also,it looks like maybe,the rear wheel inner wells have been removed.

All these would conspire to aggravate flow,especially the blower.

I'm including a photo of the HR Camaro and also a shot of Gary Spencer's # 630 Camaro,which sports the Pro Stock scoop.
I've also got a shot of the underside of a 1944 North American P-51D.I think you'll see a resemblance to the HARWOOD scoop.
These would be considered a modified Bauman snorkel,with reflexed,double-radius inlet,to defeat both vena-contrata inlet losses,as well as prevent separation on the outside of the scoop,with minimum frontal area added.Inside,these scoops provide for a 7-degree divergence for static-pressure regain and air gap to allow proper carburetor metering.
The "raised" inlet addresses boundary layer issues.
Walter Korff chose these same scoops for the 409 mph Summers Bros. Goldenrod.
When Al gets free I'll post the pics.
