My car gets very hot, as it is BB and has the black/grey interior. I am going to put a computer in there soon, and want to keep at as cool as possible, even when parking in direct sunlight. I was thinking about getting some of those reflectors you put in the windsheild to block sunlight. Do those really work well enough for me to get them?

Also, I'd get the rx8 branded ones, I'm not that trashy

 

The Sun Deflectors do work pretty good plus protects your interior from UV damage. Also i would get WeatherTech Wind Deflectors.

 

Wind deflectors? why would I need that...

 

So you can keep your windows cracked during the day and not have to worry about rain getting in your car. But anyway the windsheild sun deflectors do work.

 

Oh, ya. That makes sense. But I'd just crack them on days when i know it won't rain. I'm more worried about it getting like 100+ in there on an 80 day. But I like in Texas, so in the summer it gets 100 outside, so I'll do what I can to keep it as cool as possible, because with a computer in the trunk... it's gonna get toasty. I am thinking about also running a line from the console to a fan that will suck cool air from the cabin... but I digress...
thanks for the advice.

 

window tint = your friend BUT when the car is off so is the computer. dunno bout the window deflector things though. What is the purpose of the computer, music, data analysis, ecu adjustment/booost control?

 

Well yes, the computer will be off... but it will be very hot upon startup. and It's for nav, music, all that stuff. Will maybe put OBD scan in there, but at the moment. Mainly navigation music videos internet that stuff.
