Cooler ambients perhaps?
Or use a less restrictive screen and close the shutters some at very high speed where the aero matters most? :) |

Hey, I'm just throwing out food for thought for everyone, I'm not saying you should do it! :)

one thing to remember is - December at Thunderhill is most likely going to be 20F-50F

I've read an engine's wear rate is dramatically higher when it is warming up/under optimal temps vs high revving at optimal temp.
for a street car, it is started up cold a minimum of 14 times a week (going and leaving work), 700 times a year. for a race car, it is started up cold may be 30 times a year tops (that would be a lot, average racer races 10 days a year). imo, for a race car, most wear happens at high revving at optimal temp. |

The last time I did a Thunderhill event in December: -The car, which sat on an open trailer all night, was frosted over from front to back. The low was ~25*F IIRC. -I tried pouring a cup of water on the windshield to de-ice it - this is known as a "terrible idea" to anyone from the east coast, but in California it's how we defrost windshields. Apparently Thunderhill is on the east coast, because the water I poured onto the windshield IMMEDIATELY froze. -The driver's side door lock had nearly seized - luckily the passenger side worked, but it still took some effort to unlock the door from the inside. -We arrived at the track at 7:30am - the trunk would not open until shortly before 9am (frozen shut). -I have a photo of the car sitting on pit lane, waiting for its first session, with ice on both sides of the windshield left over from the ice scraper. |

true. but that don't apply to race car as much.

Tell you what, you build an enduro car with shutters and we'll see which solution works best.
Tearoffs and other simple stuff (strips of tape to add/remove) works, servo motors and delicate mechanics don't :) Even a simple cable pulling on a spring loaded shutter can jam when you really want it to work. |

Now you're just getting technical lol and I was just giving input to "Track's" question. I'd pick 195 if you can keep it there, I've read somewhere where it will wear less at 195 than 180. I have mine at 180 w/ 180tstat since I don't have a reroute yet, and the supposed drawback of a re-route-less setup is Cyl 3 and 4 run 20* hotter.
Never really anticipated the coil months, but no big deal, i can seal off part of the radiator if it runs reallly cold at RA. Doubtful though. |

It's your raison d' etre and the right frame of mind when building a system. You're also an engineer and suffer from, well, thinking too much.
aka K.I.S.S. :) |
Hey what do light plane shutters look like? They need to be reliable and freeze proof, right?

Questions for u engineers ? Most of the teams are from socal. We don't know what snow look like. Are there any particular issue with low temp on car parts ? Will regular wiper be enough ? Will say any parts become brittle ?

For racing, I would consider tire choice carefully considering the temperatures. Plastics are a bit more brittle when working with them, but I generally try to avoid working with them in the cold. Working with 28 y/o plastics in my MB is just as much of a pain. If you have the option of a mostly enclosed (3-4 sided) work area, get a heater of some sort for both your sake and the parts. |
i would say about the only thing would be to get premium wiper blades rated for cold climates. oh yeah, and sorry jason, but gotta say what everybody's thinkin' "fuck yo shuttas fool!"

I haven't used it much myself, so you may want to try it before committing to it, ie see if it smears on the window. what not. But its certainly a good idea to try |
just dont put HOT water on the windshield. or as they say "your future former windshield"

in that case you can consider it the removal process.

More details on defroster? I'm still looking into option to make my gutted car driveable in rainy/winter conditions.
