loosing boost


Recommended Posts

When I first installed my vortech supercharger, I was getting 9-10 psi of boost, but lately my gauge has only been reading 4. What would cause this. My tranny is having some problems, would that do it, or is there something else.

Sounds to me like you have a leak in the piping. What kind of problems is the trans having?

 

 

When I am really getting on my truck and in high rpm's, above 4000 or so, before the truck shifts, the rpms jump and then it drops down into gear. Not really sure what the problem is with it. It is going into the dealership tomorrow or the next day and I hope it isn't something serious.

I checked all the pipes and the clamps are all tight.  Do boost gauges tend to wear out or anything like that???

 

Is it a boost/vac gauge or a boost only gauge?

 

My mechanical boost/vac gauge now reads -3" at vacuum instead of 0, causing my boost reading to be inaccurate. Could be your problem.
