Why would you take the thermostat out in the first place? It doesn't do anything to help with cooling and in a lot of vehicles actually causes an overheating issue because it is used as a point of restriction to force coolant through other routes that would otherwise see very little flow if not for the restriction the thermostat provides.

 

^^^ Maybe Shr3da is talking about removing a lower temp thermostat and placing in the stock one?

 

Yup. I use Mazmart's lower temp thermostat. I'm not worried about cold weather in TX tracks.

 

Yep this is what I'm doing.

 

Leave the cool thermostat in and put a piece of cardboard or aluminum sheet (painted black) over 1/2 of the radiator for street use. Then pull it off for track. Maybe some velcro strips for easy on/off

 

You are a thinker team! Thanks for the advice.
