is your battery good? mine didnt boost when i had a dead battery. also it usually has to be under a load to get boost. i can only get 3psi when i floor it in neutral. but i hit 10psi when im driving. take anything you have on the compressor inlet off and see if that helps.

also do you have a boost gauge installed? what is it doing?

spin the turbine by hand it should spin freely, also, when u start the car the turbine should be spinning freely. stop it with your hand (at idle), and it should start spinning again when u let go.

if that doesnt happen, the turbine might be rubbing against the back housing. (happened to me)

Its safe to get your finger in there ?!

as long as its at idle yah (just dont stick ure finger and rev) use something soft IF YOUR CHICKEN (j/k)

hooohaa2

how was the dead battery causing you to not boost? (was it because your car wouldn't start? lol)

i have no idea.....but i put a new alternator and battery on there and it went from 0 to 10psi. i'm still confused myself as to what the alternator and battery had to do with it.

i would say keep fingers well out of the way of the turbine when the cars is running regardless of rpm ,leave the engine switched off and rotate it by hand, there should be little resistance on it. Have you had the turbo rebuilt or rebuilt it yourself by any chance?

on ur air intake, open that and run open DP. hopefully the turbo's shaft isnt locked up. my .02
