I'm cross-posting this from my Spyder build thread in hopes of generating some knowledge and advice.
Has anyone here incorporated a Beetle thermostat and flaps into their cooling system?
It's a serious question that arises naturally from my rear underpan effort. Since we're doing the full "hot-side-hot-cool-side-cool" treatment the question arises first of what to do about the oil cooler air (ducted out the back of the Raby DTM), which I've solved pretty much, and second what to do for warm-up since, if this all works as designed, I'll have a car that ducts virtually all the hot cylinder air and exhaust pipe heat down and out and behind the vehicle, leaving little or none to recirculate through the fan.
—all of which should be a very good thing ... once the cylinder heads get to 250 F and the oil temp reaches 180 or so.
But when might that happen??
So, yes. I'm pondering ideas and studying old Beetle thermostats and flaps.
No one here uses them, or anything like them, on anything?
