I have an 02 with vortech supercharger and aftercooler. installed my boost gauge and noticed full boost is only 6 psi. I thought the vortech normally ran 7-8. i checked vaccum leaks of course there are no CELs thrown. So i dont know if maybe that is normal with some chargers. Also if the belt was slipping could you hear it?

 

start by checking the belt

 

Which gear are you testing this in?

 

Is your boost gauge accurate?

 

yea the gauge should be just because this was a preowned kit and the guy before told me that he was boosting 7.5. and i am testing this in all gears, i will roll in first then hit it hard all the way through third. everytime max psi is at 6

 

First, check the belt for tightness. Do you know the steps in tightening the belt?

 

yea i thihnk xviper posted a DIY on that, i will check.. question is if it is loose just a little will you hear it squeal?

 

the answer is NO

 

sideways, do share!

I remember comptech's thing was to tighten it as hard as u can push the tensioner pulley against the belt. After, they say you should only be able to move the belt no more than 1/4'' either way by the tensioner.

Is it possible to 'overtighten' a belt?

 

Id like to know the steps in tightening a belt
