I had issues in massachusetts cooling my motor with a big radiator novi2000 and the stock fan, so i cant imagine how vegas is.
Sell the hellion kit and put that money towards an 11:1 big inch motor. If your gonna hit the dragstip just get a 150 shot for it. I was planning on building a turbo motor and there were a few circumstances that led me to my current combination, and i couldnt be happier. I just put my taurus fans on with a simple fan controller, and it hasnt run hotter than 195 yet... and its already run an 11.30 driven to and from the track(60 miles each way), runs on pump gas, yada yada yada. So in the end im glad i didnt do a turbo motor, i had alot of problems when i had a charger on it before, and i see alot of guys that have alot of issues with power adder cars.
When a boosted motor is right, there is nothing better, but they require a ton of attention and there are always bugs to be worked out. Good Luck
