What is my stock thermistat set at? i was told I should install a stat w/ lower temperature w/ the super charger.

I believe the stock tstat is 196*. I have a 180*. There was zero difference other than the car ran slightly cooler, no performance difference.

edit: since you are supercharged, you may actually see a performance gain.

TY, thought so.I went to Auto Zone today & they showed two stats. One was anOEM stat@ 180*, the other was 195*, so I confused me.[:-]

Running a lower temp tstat will do nothing for you unless you upgrade your entire cooling system and tune your electric fans correctly. You will get no gain out of it otherwise. On a S/C application they say to run a cooler one so it will help with detonation but again if you don't upgrade the cooling system and tune it will do nothing for you.

On my car I use to run 32* of timing without detonation with just a 180* tstat. Now that I have installed an electric waterpump, aluminum radiator and tuned my fans right I am running 38* of timing which equals out to about a 15hp gain. My car is NA so don't try to run those timing numbers on a S/C car.

I think that the Kenne Bell supercharger kits come with a 160* stat. If you go with a 180* one, you can change when your slow/high speed fan comes on. I set mine to kick on right at 180*.

160* is bad to run in a fuel injected car. The computer will read that and think the car is still in warm up mode and use those fuel tables to keep the car running. The warm up fuel tables are very rich and bad for performance.
