What is a 180 Thermstat?

What is a 180 stat? Would it help my drag times out on my truck with upgrades listed below? What kind of hp gains should i expect? How much do they cost? would it work well in AZ with the 100 degree temps and low humidity?

Thanks

Oh ya what about electric fans? Would that be effective in cooling my engine down in Arizona?

In those high temps electric fans may not move enough air and it will add a lot of strain to altenator too (about a 30 to 40 amp load for dual big fans) and can short life in those high temps. Also if the altenator fails in that setup between the engine injection current draw (about 20 to 25 amps) and electric fan draw (30 to 40 amps) before you add lights and such you would have a run time of 10 or 15 minutes tops to limp truck to safety (if even that long) on battery vs about 25 to 35 minutes or more with a engine driven fan. On thermostat, I would not try it and I know I might catch some flack here but let me explain. Your raditors cooling abilty is based on tempature defferentail between core temp and air temp flowing threw it. In 100+ temps with A/C on the air passing through condensor can be heated 25 to 35 degrees or more. If you factor in say a temp of 105 plus 35 you get 140 degree air on core and only 40 degree differentail in when coolant start to flow which means temps will rise more before it stabilizes. With a 195 there is a 55 degree differentail and about a 35% increase in heat/BTU tranfer abilty to the 140 degree air when stat starts flowing. AN 195 will give you more stabel temps in that situation.

I just put a 180 Hypertech t-stat in my truck. The temps are now 2 bars lower than what it was before all the time. Truck drives great, no loss in mpg, A/C is cold enough to freeze you and the heat is still hot (at least when morning temps were around 40*). Whether it's a good idea or not, don't know, but I've not had any trouble. Only reason I got it was that I had very slight pinging with my Wester's when under medium throttle. Since putting in the 180* t-stat, no more pinging. Especially if you sit alot in traffic, at 100*, I don't see how a lower t-stat would hurt anything. Chris

I don't mean to insult anyone's intellegence here:

A 180 stat, is a thermostat that opens at 180 degrees, as oppossed to the stock stat which I guess is 195? Anyways, this allows your engine to run at a slightly lower temp, which is almost always a good thing. The only drawback that I've heard of is for those of us in colder climates. It takes longer for the engine to heat up. So on cold snowy days, we'll all be at work before the heat blows hot air.

Electic fans are always nice, but they do drain your battery. I'd hook them up to a manual switch in the cab, so you can turn it on and off before you toast some punk off the line.

That's my 2 cents.

Good luck!

It is a lot cooler in KY than AZ, I know I have been both places. 100 is rare there, it is a way of life in AZ for months at a time. I have seen over 110 in shade down there in AZ and never in KY and it is much hotter in traffic too there from road heat.
