I see that a lot of people have drilled holes in their termostats. I did not do it when I installed the one I got from Intense, I dont remember reading anithing about it.
But now I see that every one and their mothers are doing it.
Should I take it out & drill it? What is the diffrence? How would it help me?
I understand the idea, that there will be some circulation, but is this a must?

It is not a must. This is something that has really taken off here at BC and is not common place at most other sites to the level here.

I run a non-drilled much of the year and you should be fine either drilled or non drilled. If we ever worry about it..remember your car shipped from the factory with a non drilled 195F.

thank you, I feel better now.

We are here to help.

what exactly is the big deal with 180 t-stats. what does that really help. ok i understand it opens 15 degrees earlier, and starts cooling a lil sooner, but doesnt our engines run better at 200 range?

Depends on what you mean by better.

For a modded car, cooler engine means less apt to detonate under high boost conditions. If you mean better gas mileage or emissions then yes a 200-220 engine will perform better in that regard.

yeah thats true. i wasnt even thinking about the detonation aspect. thanx for the info.

does that mean it'* the drilled 180 t-stat that has caused my mileage to go down? And not the cheap spark plugs?

I was about to put the old ones back in this weekend because of it.

Most likely yes

i lost 5-8 mpg putting an 180 degree t-stat in
