vortech v1 running vacuum??

[basler]

just bought a 90 gt supercharged,, has been sitting for two years. changed fluids and everything befor driving..

the car is running in the vacuum side of the gauge. and was told that the supercharger may not be boosting. I'm new to the boosted engines and actually this is my first mustang.

was hoping to see if some one might have a clue on what my problem is or if i need to rebuild my supercharger.. or replace with a new one.. like i said its a new to me car. im not sure on engine mods besides what i can see....

So it doesnt go into the boost when u get on it?

ive seen it up to 1.5 but thats it. and that was a pretty hard launch. but i havent driven much due to the fact idk if its hurting the car

you have to be nearly wide open throttle to see boost.

What does the gauge read when car is not running?

Is it an Autometer?

Have you check the hose connections?

Mice like to gnaw on hoses.
