my buddy erick started tuning my car today. We adjusted some things while idling, went for a drive. After 3 miles we hit 231 so i turned back around before it got too high .
We're still chasing this issue. Im going to list here everything we've tried here so its not reasked in a later post.
Swapped from 160 to 180 thermostat
drilled hole in thermostat
capped heator ports on pump
looped heater ports on pump
moved front steam vents to upper hose
checked to make sure headgaskets were installed properly
made an air dam to scoop the air towards the rad

If you look a few pages back rad is as high as you can go . Its 1/4" away from hitting hood. Pretty much stock height.
I have just a 15 dollar overflow . Is that considered an expansion tank or no?

Im running microsquirt.
I have a summit overflow that was like 10$ and hooks up to port above rad cap spring.
An overflow comes off of the top port on the radiator just below the cap. An expansion tank is in line and will be pressurized to what ever your cap is. Some have the cap actually on the expansion tank will be the highest point of the system.

What exactly does the expansion tank do?

Verdad Gallardo Ensures that you have a full coolant system also allows for a known level within the system. An overflow tank just catches any extra coolant within a system. If you have an expansion tank, the radiator cap should be on the expansion tank and a blank should be placed on the radiator.
I always found my coolant temps to be a little more stable with an expansion tank. Not sure the reasoning behind it but i know most LS cars run expansion tanks over overflows.
But if your getting that hot, you got something going on. Maybe its something like cam/ignition timing.
Ive dropped a few degrees by adding timing before, but you are real hot.
Also, make sure your coolant temp sensor is calibrated correctly. Let it sit over night, turn the key on and the air intake temp and coolant temp should both be close to ambient temp.
