You mentioned a plume of white smoke from the exhaust. Just to be on the safe side, I'd check for a blown head gasket. If it failed during a sustained high rpm-high load run the pressure spike in the cooling system could easily blow a cooling hose off. In addition, white smoke from the exhaust indicates an engine burning coolant and is a classic symptom of a blown head gasket.

Unfortunately, even the shortest burst of white smoke is a bad thing. @Capt Spaulding is on point.
Look for soot or oil in your coolant. You'll see it build up on the inside wall of your reservoir.

@Capt Spaulding @Ultramaroon It was most definitely a nice big plume of white smoke.
Ill try to check the reservoir... But with the MAPerformance kit, they have to remove the stock reservoir and put in a custom one. So all it is, is essentially a small tin can, and you cant really see inside of it. There is a shop I trust right next to my work... Ill go talk to the owner and see if he can slip my car in to run some tests. |

Do an oil change and inspect the oil for signs of coolant contamination. Also inspect your coolant for signs of oil contamination, do a hydrocarbon test on the coolant. That plume of white smoke should not have happened. IMHO your thermostat is working fine, but the engine is building heat quickly and the radiator is able to manage it, but the heat is building due to some sort of leak (probably head gasket).

Lol, OP had massive coolant spillage all over the engine bay and you guys assume his head gasket is blown instead of some of that coolant making its way to the intake and being thrown out as white smoke..

Every single inch of the engine bay is covered in dried up coolant, and I even did my best to wipe some of it up. It used to look so beautiful |

How did you know that the "white smoke" was actually coming out of the tail pipes in the first place? Not like you could see them from in the car. Could it have just been a puff of steam coming from under the car when it blew?

I spoke with the owner of the shop, so he is well aware of my situation. But he will not be able to get to it till next week.
So its a waiting game for now. @Tcoat FYI I spoke with LJ at Fullblown, and they use a 65C thermostat for all their builds, so I was thinking about picking one of them up. |

follow these directions with a quality thermostat, (i.e. NOT mishimoto,) and you can do it on your own. Edit: This link may also be helpful. Mishimoto says to just turn your heat on high lol. http://www.ft86club.com/forums/showthread.php?t=9883

I think is pretty safe to rule out any head gasket issues at this point. Some people here like to head straight to the worst case scenario instead of starting at the basics and working their way up. From everything you have said there is no indication that you have any head gasket problems.
Some other things to consider are: Rad cap - The rad cap opens and closes under certain pressures (I have no clue what they are) not by temperature. When a certain pressure is reached it opens slightly and lets a very small amount of coolant into the overflow tank. When the pressure drops it sucks that coolant back into the rad. In an over temp situation the cap opens even more in order to release pressure and prevent damage to the engine. The overflow tank and the hose leading to it are never exposed to high pressure under normal situations so for you to blow that hose off you went into a high pressure situation and the cap opened all the way. I have seen special caps for sale (a TRD one at least) that open at a higher pressure to prevent this scenario when running a modified engine. They would still be within a "safe" range of pressure but higher than stock so it may be another worthwhile addition for you. Fans - It is possible that one or even both fans are not kicking in soon enough for your engine mods. This is another thing that could be indicated by the fact that when you ran the heater it leveled out a bit. Either you did not get enough flow (thermostat) or there was not enough air moving through the rad (fan) and you hit the critical temperature/pressure to blow the coolant out. Hoses - You could have a collapsed hose someplace that is restricting flow. This is probably the easiest of all to check but also the least likely. Low coolant - It is possible that you were low on coolant before it blew. Of course that would allow the temperature and pressure to build. From what you have said though I think you would have noticed that since it would have been a gradual increase in your operating temperature and you would not have had the consistent readings you have stated. The answer that has been said already. You just need to fill and bleed the system.
