I was on my way home from the gym today, and when I got on the freeway, I noticed that the car was boosing up to 8psi. This is with the stock JR pulley. It usually boosts up to 7psi at full trottle, but this was at maybe half throttle. Is it normal for the JRSC to start boosting more over time?

I'm not sure if this is a problem or not, but it's never happend before so I wanted some feedback on it. Thanks for any help.

 

i heard if u have a clooged cat make u boost a litle higher then normal that wat i heard

dont hold me to this

Agreed, it's been seen that exhaust restrictions will increase the boost seen in the intake...

 

Normal. Max boost pressure will change slightly with weather (temp, baro pressure).

 

Yep, a PSI here or there isnt a big deal, it will change with temperature, humidity, etc.

If it gets to be a consistent thing, and it gets higher and higher, I would look towards a major exhaust restriction, IE clogged cat.

 

yup, stock manifold, cat, exhausts... I peaked at 8, maybe 9 sometimes. its normal
