Thermostat Temperature

[90ARAPAJ]

2 Quick questions,

1. I have the hypertech tuner and my car has always been at 160 degrees (boltons only) but i heard running your car too cool is bad? I dont want it stock so my choices are 160 or 180 degrees, what are the ups and downs/ which one is better?

2. I have the ZR1 corvette rims all around (285s) Can i put a 305/315 size tire in the back for more traction without rubbing? I'm already sorta rubbing sometimes when i take a turn fast or drift but i dont want it to get worse by a bigger rim. (I have another thread on the rubbing problem). Thanks guys.

No. 1 : I chose a 180 degree thermostat for our car. It generally runs in the 183 to 194 degree range depending upon load, outside temp and speed. Even with the 160 degree stat, your car will probably see actual temps closer to 180 degrees, so it should be fine. As you know, you have to reprogram your fan temp settings to take full advantage of the cooler thermostat. Also, do not rely upon your dash temp gauge (unless you have a '98) as it is only an estimator at best.

Well, I have a temp cap on my radiator and at a 160 degree setup(fan settings too) my cap reads 180-185 degrees on a hot day with me driving normally and punching it on occasion. Also, my car is a 1998 model.

Sounds about right. I noticed that you have a '98 right after I posted that.
