(Click here to view the original thread with full colors/images)

I have a 95 GTwith a 9 lb powerdyne supercharger. I can drive the car around for hours and it not run hot. As soon as i start to get in the throttle hard and turn up the boost it runs hot. I can take off the blower belt and drive it hard and it wont run hot. Any suggestions ????????

could be a few things. not enough fuel pump, not enough injector size. radiator needs flushed. your probly running lean under power.

You're oil looks good, I guess?

ANYONE who starts throwing big boy's toys on cars like blowers, nitrous, major bolt-ons, etc. need to invest in a wideband A/F Meter.

If someone could get their ride dialed in on a nice fuel curve, it would eliminate sooooo many problems that arise from modding cars.

Very good idea!

Definately sounds like your going lean. Are you still on your stock fuel pump, injectors and harware? I think those are 19# injectors, at those boost levels, your prolly making around 350-375 HP, the factory injectors are maxing out, you should be using somthing in the 30-36# range, also upgrade that fuel pump and pressure regulator. Hope you get it worked out.

about what oil and coolant temp would you run in a 350 or anything else? what temps should a person consider overheating?
