Subject line is the question. I am curious what boost the 275 has compared to my 210. I have 24 psi max.

I have an ISB 300 in our '04 Bounder 39Z, and while I don't know if this applies to your engine, according to my VMS PC, I attain up to 30lbs boost when under heavy load conditions.

I also have an ISB 300 (2003 model) and the highest number on my dash guage is 30psi. Under heavy load it seems like the needle is pegged at the 30 mark. Under normal flat driving at 65mph, I run between 16-19 psi.

I have a Banks Stinger system which includes a pyrometer and boost gauge. 23-24psi seemed to be max boost before adding Stinger. Now at full throttle, I see around 35psi. My engine is the 275ISB.
