Performance t-stat...interesting. Fooling the engine into thinking it is running cooler to use more fuel isnt performance...its wasting. modern engines need to run warmed then thier predecesers to fully burn off the A/F mixture. adding extra fuel only makes it run rich, which can lead to the catalyist in the converters to over-heat and melt. on top of that, unburnt fuel will seep past the piston rings washing the think oil film off the cylinder walls (which the piston rings ride on). once it reachs the crankcase it will dilute the oil and enter into the bearing passages, again washing the oil film away and decreasing bearing life.

I am not really in it for performance I am looking to keep the engine running a bit cooler, like discussed in another thread.
Wayne you wouldn't happen to have that Maverick part number? What makes you think it is the Maverick one? I will call Summit and see what they say about it and maybe they have something else I can use.

So to sum it up, you will not have catastrophic engine failure from a 180 stat for Christ sake! Geeez, relax optical illusion....

I have a 160* t-stat in my Impala, I have the PCM programmed for it. It is actually a common mod for these cars. Granted it was in Conjunction with a complete engine overhaul, But I'd say about 90% of the Cars in the ISSCA have this done and most of them have increased their ET's and not sacrificed noticeable mileage.

Anybody can convince themselves that a mod does nothing, or the mod isn't worth the money, or a Ranger isn't a race truck. The trophies I have acquired proves that Rangers are race trucks and the guys that think it isn't worth it are always gonna be slower than me.
When I first started racing I was running a 4banger Saturn. I was stuck at 16.01 N/A. 15.99 became the target (obsession) and spending $200 to shed 2/100's of a second off my 1/4 mile times was worth it. The same $200 for a small gain to 90% of the guys here are a waste of money. Everyone has different goals.
