So as the title states, Im seeing some bad motor problems and one of the main problems is overheating while under boost. Ill list all my mods at the bottom. I took the car in a few weeks ago thinking I had a possible Head Gasket Blown.

The shop had the car for 3 days and at the end, they said they fixed everything other than it needed a tune. I recently moved to El Paso TX from Tampa FL so yeah 4k elevation diff and only 91 Gas here.

Well First off I used some Lucas Octane Booster which fouled 3 of my plugs, Then supposidly the radiator was clogged so the flushed it, also they checked the oil for coolant leakage and nothing, which i figured there would have been, they also changed out some hoses that were supposidly colapsing due to oldness, and a new thermostat just in case, lastly a new radiator cap.

Now when I got the car back it seemd a little slugish, So I put in a set of new NGK TR6s gapped at .032, Then I took her for a little drive and she ran like normal. So i figured hey lets try her under boost, so I got onto it and within 30 secs of coming of the accelerator at 120, the heat was at 3/4 and still climbing. I started to back way off and drive normal and it started to cool down within 5 mins.

As I drove the car 10 more mins and got to the house it was heating up again little by little and I could see water coming from behind me, I poped the hood and coolant was everywhere, and the cap was steaming and the coolant was just booiling hot.

Some of the problems I noticed before was gases trying to escape from the radiator cap, I didnt smell like exhaust fumes but was just pouring out from under the cap, with the radiator cap off I noticed every once in a while bubbles but there were 1 every 5 mins or so. Also the fan was turining on and staying on didnt seem intermitent, Every once inawhile I do notice some white smoke but very little coming out of the passanger side Tailpipe for maybe 1-2 mins then it stops

So after a long ranting on I dont know what the hell is wrong with my car other than a blown head gasket anyone else have any freaking clue?
