Fiberglass hood mods... crazy?

Alright... Not to be a wet rag here.. But your running into a couple of problems...
First off.. You need to strictly define your goal. Is it to relieve underhood pressure? vent hot air? or make your car faster?
We can do all three of these things. But not exactly the way you had in mind.

First lets go over the reasons your idea will not work.
1. the pressure under the hood is Much less than that at the base of the cowl. For the reasons others have explained.
2. even if you could get it to rise up more the air would go into the engine compartment, not out.
3. As for the raising hood Idea.. All I can see that's really doing is acting like a big wing and creating drag... A LOT of drag. has anyone made successive passes with and without? id say you could lose as much as a tenth.

Other Ideas.
To make it run faster you could do a couple of things.
1. cold air. Ducting cool air in is a GREAT! way to cut your times.. it can lower it by more than two-tenths in some cases.
2. A belly pan would help and hurt... It would hurt the airflow out of the engine compartment. but would help smooth the airflow under the car. A different way of doing this would be a 3/4 belly pan(uncovering at the engine compartment. you could help the overall aero and the airflow out of the engine compartment by doing the 3/4 length and a front spoiler.. I'll explain the reasoning later. As I'm running out of time..

if you do decide to do the hood mod and it doesn't work... Send it to me! I could really use it! LOL! Sorry I had to stop mid-post but I have to get off.. I'll finish it next time I'm on. Hope this helps
