I remember a thread a long time ago. Can some one tell me the benefits of raising the rear of the btoom. Do you think it would have any effect on air flow over engine lid, in a positive way?
Opinions? |

I like the rear louvers for the engine bay...
Al Lager, my guy in the know, says that the vortex can actually push the car forward, by creating a greater suction behind it than the wind resistance in front. He says that the same effect made VW busses more aerodynamic than damn near anything out there at the time. Including ferraris. But putting holes in the windows ruins the "catching" part of the effect. On the other hand- he also says that putting the holes in is the best way to reduce drag on these cars. SOOOOO.... I guess it depends on what effect you're going for. And it would be nice to know wich offers the most performance. Al says that they always let him race with a passenger window in place and he used a small tab on the body work in front of the driver window in combination with a "safety net"- but not there for safety. Then you could reduce the drag on the rear window by reducing the amount of air driven hard into the cockpit and maintain the unique area behind the window for the vortex. I spent all afternoon pumping him and another guy for info- and trying to fit 7" wide phone dials under stock fenders..... (IMG:http://www.914world.com/bbs2/html/emoticons/sawzall-smiley.gif) |
