Hood Extractor for Downforce

[truegearhead]

I have it all pop riveted together (partially). Now I need to file down and clean up the edges, take it apart, wrap the hood and then drill and rivet the rest of it together. All in all I probably have a full day wrapped up into getting to this point. A few lessons learned

1) make template after template, use lots of cardboard.
2) make panels one at a time, rivet them to the hood then recheck your templates for the remaining pieces. dimensions change as the rivets go it.
3) change your jigsaw blades often to keep cuts clean.
4) use tape to protect aluminum surface
5) don't cut aluminum big with the plans to trim. Get the template 100% right then cut
6) measure the straightness constantly, it will want to pull in different directions.

I'm liking your improvements to it. How do you get under the hood now? It looks like it's riveted to the body

Thanks, I played around with designs that would allow the good to swing up but it would have been a mess. Now to remove the hood it needs to be lifted off. All of the aluminum you see is attached to the hood.

Ok now I’ve really lost. I posted this up on Grassroots and a very knowledgeable guy that’s been helping me told me that due to the size of this thing what I really need is a “cowl flap” and to make it efficient it Really should be adjustable. What if....I used the Boxsters 70mph spoiler deployment system to automatically raise and lower the flap...and change the pitch of the rear wing. It would work in the opposite way the stock wing works though it would maximize downforce below 70mph. I wonder if just reversing the poles on the stock actuators would reverse the direction they operate, anyone know? Alright my crazy pills are wearing off.

Ok I’m back and with some more crazy piles. So using the stock Boxster actuator system won’t work because it deploys at 70 and retracts at 45 or something. I would need a signal that’s consistent at 70. I wonder how the stock system is being signaled, maybe they’re is a consistent signal I could use from it. Anyone know?
