Either the belt is slipping,an air leak between the SC outlet and throttle body, or the SC isn't moving enough air to create boost. You'd have to call Vortech to price a new SC, or rebuild your current one.

 

yeah you have some type of air flow problem.map sensor wont cause no boost.

 

i did your test pressure thing and the turbine is moving air very hard got to take it on the road for a test after few adjustments to a loose seal.

 

you mean an boost hose was loose or a seal in the s/c was loose.

 

boost hose.

 

Still no boost!! it is the knock sensor I think they broke it when they installed my clutch. I am going to get to pay for it!!

 

The knock sensor isn't going to cause no boost, it will have a check engine light for the sensor code.

 

you might have too unless you can prove it was broken during the install.

 

Ok then after all the trouble shooting I am going to have to say the belt is slipping.
Has to be everything is hooked up and everything is running like it is suppose to. The turbine is fine as far as I can tell it blows very hard.

 

yeah went by the shop they said no problem and ordered a new knock sensor for me.
