Overcooling on stock set up?

[bakonick]

all car usually have 82 to 92 thermostat for fuel economy and good heatin at winter .
the more cold the engine the more power you get ,also you increase the fuel consamption .
usually the cars at morning when they are cold the go better.
all competition thermostat are from 69 to 72 .
if your temprature is around 70 you are ok.
check your thermostat if dont have any install a new one .
so if you want normal drive install a 82 you want to go to play with the car time to time install a 72 .
