Turbo Boost?
Thanks for your input
Tom
if i am rolling down a flat road at 60 mph cruising with no load i will only see 1-2 lbs boost.
if i am standing on it, 3100rpm towing 20,000 lbs up a 17% grade, i will see 15+ lbs boost.
350F sounds low, though, for 60MPH; I'd expect more like 550F. 2-3PSI sounds right, though.
Remember, you don't *want* boost unless you are able to use the air. More pressure = more wasted power in spinning that turbo unit and compressing air.
But if you can use that air in combustion, it's a net massive plus.
If you're not getting black smoke, you've got plenty of air for the fuel being burned.
if your looking to max what you've got,wrap everything you can,add a turbo blanket,intercooler and max the fuel.she'll boost even lower at no load cruse,but have more power and higher efficiency.

if your running an old tiered worn out ip and injectors that have pop pressures of half what they should be and who knows what for timing still,you could be down a whopping 50 hp or more by now and not even know it.
get your ip reman,drop in a fresh set of G codes,set the timing to 7 - 8 BTDC then do the above wrapping,and you'll think you set a whole new engine under the hood.intercool her and max the fuel and you'll think your running a 94-97 psd with 4.10's.probably even a bit stronger since we have more base compression to start with.been a long while since iv run those trucks now.
