I want to get a 180 tstat for my car, but which would be better? Intense offers one, and so does zzp. does anybody know if one is better than the other?
 


They're all the same, I got a 180* from zzp. It works fine. You can even get one from awful zone for a few $$. U might want to replace the little rubber gasket while your at it.

what is the difference between a drilled tstat and a regular one? Will it perform any differently than a regular 180?
 
It'll take longer to heat up. It's drilled out so it can't completely close.

Though it's a moot point as you can get fail safe thermostats that will go all the way open if they fail, as their default position. Old thermostats all the way closed was the default position.
 
Maybe I had a bad one, but the drilled thermostat I put in my Silverado kept it from warming up as fast in the winter.

Either way, its true intention is to allow a small amount of coolant through to keep the heads cooler instead of a stand still of coolant which can heat soak them. That way, when the thermostat does open, the heads are ready to go instead of being extremely heat soaked and in need of cooling.

The holes are not large enough to make a big difference if it sticks shut.

From Wizbang at EasyPerformance:

The 180ºF thermostat was modified by drilling four small hoses around the thermostat body to permit a small amount of coolant flow through the cooling system even when the thermostat is closed. This modification results in reducing the thermostat's opening reaction time when the engine is relatively cool to begin with and is then challenged with prolonged wide open throttle runs. Without a drilled thermostat, the temperature of the cylinder heads can become quite elevated before the thermostat has a chance to open and establish coolant flow through the heads to cool them down.

Does anyone know why they want to get a cooler t-stat? Do you know why you want your engine cooler?

The entire colder t-stat idea is to prevent KR. The colder the engine is, the less KR you should get. But if you mod correctly and tune your car, you should not have any KR to contend with. Thus you should be able to run a stock t-stat and get better mileage and better performance.

My personal opinion is stick with a stock temp t-stat.
 


It's simple, the colder the air getting into the cylinder the better. It might be minimal gains but some people take what they can get. How many of these gtp's around here are honestly modded correctly? I can tell you pretty much everyone has kr, so that'll never happen. Everyone thinks it's ok to have it... :th_angry2: it's a $10 blanket imo worth every penny.
 
im getting the tstat because i am going to be dropping pulley sizes soon after i get the plog, tstat, and colder plugs... im not just doing it for the hell of it
