So i went to get tuned today on stock boost with a greddy emanage.

Bad news is that its only reading the most at 2.5psi if that....whats going on....??

When we installed it..we initially checked the belts after we took it for a run but after that we havent checked it since..

I am worried something is wrong with the supercharger itself...

could it be ...

a) belt not tighten to its full potential even though it feels tight.. if not how tight should i have it?

b) i have a boost leak somewhere...

c) supercharger...if so would i notice something unusual if its not building full boost?

any help would be greatly appreciated..car runs great but only seeing 2.5psi boost..

thanks

I'm guessing (B) boost leak somewhere...

what do i get if i win?!

 

A boost leak that bad? the clamps and couplers looks secured...

could be the belt..when I bought the kit used...I used the same belt the guy provided...he told he it only had 6k miles but it was my own fault for not putting a new one...could this be it?

if it is a boost leak....ill send 20 dollars to you via paypal..lol..

 

Sounds like a leak. My car wasn't building any boost last time we tuned and spent 30 minutes trying to figure out why.

The reason? A coupler wasn't attached securely to the charge piping in my bumper.

 

slipping belt, tighten it up!

 

What is a good measuring way to see if the belt is tight enough?

 

I think its not supposed to twist more then 1/4"

 

You should only be able to twist it 90

 

this is was my problem before too lol

 

I had both problems. Loose belt and coupler.
