160 or 180 degree thermostat??

[Sean1998Daytona]

i have a 1998 daytona gtp and i was wonderin if i should get a 160 degree or 180 degree thermostat swap? i was told that getting a cooler thermostat will help increase power. is this true? and which one should i get? thanks...

[SnowFlake]

They don't technically increase power. It's a touchy subject around here but IMO just get a 180. It'll help to keep things a little cooler and by a little I really mean a little, lol. 160 is too cold though.

[matt5112]

180 if you plan on going past a 3.4 pulley or 195 otherwise.

Especially with WI in mind.

Just stay 195, 180 only makes your car take longer to warm up and 160 can actually cause damage and set codes... I read in Jerry's Tuning Notebook or whatever that cooler thermostats actually accelerate wear on an engine up to 300%.

Jerry also doesn't believe in wide band O2 sensors.

The little bit it does cool it (5-10º F), its not even worth it.

Thats my opinion anyway.

Well I dont know, I just read over it and that stuck in my head

I'm not sure how a 180 could have any effect what so ever on how quickly the car warms up.

Someone needs to edit the safely modding your 3800 thread.

I figure if it opens sooner, it would stay cooler longer, albeit a small amount?

It wouldn't at all.

if you run a 180 your ect's should be in the 180's.

[Sean1998Daytona]

ok cool thanks! i just wont even bother with getting a new one

[addzradd]

I'd recommend the 180, if you plan on doing any auto-x or really any type of racing it helps keep temperatures constant.

[tod1d]

180 if your taking it to the track, otherwise its not a good idea for a DD, I have a 180* sitting on a shelf now because I have changed my mind about using it

[dazedandconfused]

I'd like someone to come up with some conclusive evidence that running a 180* tstat isn't good for our cars.

Prove your case as well then.

down here in florida i recommend the 180 stat as it keeps engine temps between 176-195 depending on fan settings. maybe back in the day people who ran too much pulley and were lean would throw in a 160* cause if they get their car that cool and keep it there the car will command more fuel... and this would help get a better AF. this is a very bad idea and with the tuners out there and pcms it is not an option at all.

There is a thing called operating temp where mechanical devices are more efficient at. Why do you think our cars came with a 210* or whatever stat from the factory?

195* not 210.
Dropping 15 degrees is going to have zero ill effects.

ive been running a 160 and it runs a bit rich but thats all i have noticed
