Max Boost Pressure?
 

Can anybody provide the max boost pressure I should allow in my stock 617?

12 or 15 PSI?

I searched the forum and came up with those 2 numbers.

Thanks,

Thanks for the numbers. So just to brief back:

On my 83 300SD with an unmolested 617 I can turn the boost up to 15 psi with the IP maxed, and limit the TGT to 1300F as per the instructions on the "Injection Pump fuel adjustment for the MW and M pumps, pyrometer install" thread.

Correct?

Thanks for the info!

Sweet. Thanks again.
