Project Frankenmiata – The Ultimate Miata Coolant Reroute

In an effort to make sure there was enough low pressure behind the car to suck air through that taillight hole, we used a piece of wood as a bending brake to bend a little spoiler into the chunk of aluminum hood skin that was serving as our roof.

 Then we hammered a little Gurney flap onto the end of it.

This shape should ensure a nice, big, low-pressure wake behind the car to suck hot air out from behind our radiator. Just to be sure, though, we cut this spoiler off, re-attached it with door hinges (house door hinges) and then connected the trailing edge of the spoiler to a surplus pop-up headlight motor using the trunk spring as a pushrod. When wired to the brake lights, it worked like this:

 

 

This was so effective, it turns out, that at around 90 mph, hitting the air brake would create enough of a low-pressure wake to suck the trunk lid open (we removed the latch to save weight, but left the lid on to duct the hot air to the low-pressure taillight region). When racing in Reno, we took advantage of this by hanging a genuine velvet Elvis painting on the inside of the trunk lid so anyone we passed could pay their respects to the King. Amazingly, we seem to have exactly 0 pictures of this.

And that, surprisingly is about it. The full mechanical backstory of the Frankenmiata has finally caught up to the sickening reality of the Frankenmiata. If you want to re-live the horror, go back here to see all the details again. Or keep checking back for updates on our new LeMons car, which we've already (barely) started. Hint: It's a Subaru BRAT.
