Since your not concerned about looks, you could cut the bumper between the lights and rivet sheet metal to make a duct. Its almost free and should improve your cooling alot. On top of that you dont have to move anything. Also you should post some pictures of the car
Would you mind clarifying exactly what you mean about where
you think I should add sheet metal?
Please refer to the quick and dirty pic I took below.
I apologize for the angle but this bird barely fits into my garage in SF.
I was standing on the steps trying to take as low an angle as possible.
1) I believe you are suggesting that I cut where I have marked the RED lines. This should detach the tbird logo and open up the entire area underneath the hood and between the front headlights. Please confirm that this is what you meant.
Q: Also, IIRC there are a few push pins that hold that piece there. The bumper is attached in other places and will still remain secure even if I take this center attachment point out, right?
Now, comes the part that is confusing to me. I have spare aluminum or can use cloroplast (read election signs) to add ducting as needed.
1) BLUE Line: If I add a piece panel in where the blue area is, I'm basically creating a "top" so that air doesn't spill over and run between the hood and the radiator. Is this what you meant by a duct?
2) Green lines: I'm not sure if you also meant adding ducting at the "new" top of the bumper going towards the radiator and/or on the sides.
Q: If this is what you meant (in addition to or in place of the duct measured in blue), why?
The gameplan is to have a front diffuser that extends all the way back to the radiator. Any air making it in from the center section will have to go through the AC-condensor-turned-ATF cooler AND radiator. If it spills to the left or right towards the headlight or down towards floor, the side seals and the bottom diffuser will force the air through the radiators.
Thanks again for your reply. All of your thoughts are really helping us make this a badass, if underpowered track-jalopy.
