[SUPERCHARGED_GT-2005]

Ref: 2005 Mustang GT, Supercharged with procharger D1SC running 465 rwhp.. Overheating problem..BIG problem..

Hi all,

First of all i wanna thank you for your answers and advice ur giving me. My ford dealership know fu*k all about this car.. I also know nothing about engines...but im learning..

Maybe someone can help.. i have a 2005 Mustang GT Auto, I have tuned it too 465 rwhp and it goes nice..i hv lots of mods but my main mod if the procharger D1SC, i have nothing but problems with this system and i really, really regret buying this! Anyways i won’t bore u and go into all the problems cos most have be resolved apart from this..:
When driving the car fast, over long distance or 2 short sprints the car will over heat immediately and all the water will drain straight away.. at first i thought this amount of water will come from a pipe somewhere but then i realized this only happens when i drive the car hard.. so today it happened and i quickly stopped and opened the hood and found the water spraying like a fountain out of the radiator cap.. I’m aware these caps are specially designed to release the water after a certain amount of pressure (16 PSI).
My question is how is the water getting this hot in the 1st place.. i live in a hot part of the world (Dubai) but it happens even on a cool evening..After just a few quick bursts.. Basically the water is getting way too hot, boiling then being released in full though the radiator cap.. After 20 Secs its empty..

So how is the water getting to this temp in the first place..?

Latest..

I noticed yesterday when me car started over heating again that the fan did come on.. Surely when ur engine is hot the fans come in to cool the engine..i have a question:

How do the fans work, do they come on while driving if ur cars engine reaches a certain temp? Or do they come on when the car has stopped? Obviously i can’t chk while the car is moving but i checked when the car started overheating just now and the fans we not and... my ignition was off but the electrics of the car were on...?

The car has been at ford all day, i told them to chk the wiring for the cooling system - They said no faults.. i told them to change the thermostat, they changed that, they also chked the thermostat sensor and all is good.. they said the computer is showing the fans work fine.. Sometimes they work.. Sometimes they dont. I have just also changed the manifold on the car so that is fine now...they have done compression tests on the head gasket they say is fiine...all computer diagnostics show the engine is fine..oh and we added antifreeze in there 2..

The car only over heats when i push it maybe 3 times in a row or when i drive approx 140 kmph for more than 10mins... the temp will rise then the water will empty out of the radiator cap like a fountain...The car is not losing power in anyway.. its still very quick only when i screw it too much the car will overheat immediately

Does anyone out there have a clue how to fix this problem?? I’m spending allot of money and time on this car now and its becoming a liability..

Please help..

Cheers

About the fans, hey work different than most cars these days. Mine come on while driving, I can hear it, but if they are running and I turn off the car and leave it in the accesory position they turn off. My other vehicles let me use the accessory as a way to cool the car a bit longer after shut down, which comes in handy at the track.

I have a P1SC on my car, and I run her hard every chance I get. Not one time has she over heated on me.

Who installed your supercharger? I would have them check the union for all of your hoses, make sure it is not obstructed and that the Thermostat is working correctly, don't take the dealers word on they replaced it. I'd start there, I'm almost certain it will be the problem from the symptoms you describe..
