how can i possibly increase boost in my N14

i guess this will work for a cat too...mine will run from 30 to 40 lbs of boost depending on the rpms.

 

Yes boot size the same.

 

To chi charge air take spray bottle with soapy water bump idle up on cruise control an spray cooler usually on Frghtliner crack will be down pass. side

 

Bringing an old thread to life but I thought from memory the one I used to drive twenty years ago was like 42psi boost with the 525 red top?

 

10 pounds will tell you nothing to speak of. You need o air it up and see how long it takes to b;leed down.

Maybe work for a busted one, no way to see if it leaks like that.

You can not test one like that it will not build boost in nuetral.

 

Great video but a note of caution NEVER put a body part in front of the plug . It can hurt you bad if it pops out at pressure
