Lifting rear of roof, what are the benefits Options

[retrotech]

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 wish you 914 racers luck with these aerodynamic changes, these generators use energy(drag) to create the vortex's, the question is do they direct air flow enough to reduce drag in other places, or reduce lift (perhaps increasing drag). The problems you need to overcome or use to your advantage: 1. The 914 does not have a very aerodynamic shape. 2. the engine cooling uses air from behind the passenger compartment and exhausts that air under the car. The key is to direct the airflow to minimize lift and or drag. Most likely it will be a compromise between the two. There is alot of things you can do to a 914 racer to decrease drag, but many of would seem to be quite odd, look at the history of aircraft design.
