Boost PSI

[MidwestOffroad]

what type of boost you getting. stock or modified/

I know of guys getting over 35 psi on cummins and i head over 30 on a 7.3 will pop head gaskets... whats good or average.

I can get my stocker over 30 loaded, up a hill. I try to keep it under 25-27, I think that's about the limit for the stock turbo. I think 7.3's can take 35-40 before needing headstuds, rods, etc. I'm interested in this also, with my new turbo on the way. What is the max?

Mine runs at 32-35psi MAX with the garret GTP38R BB turbo under load. I have had it on the truck for the past 25k with no problems.

i can peg my 30 lb gauge with stock turbo but i have bad turbo surge at times , gonna buy aftermarket turbo soon

06 with SCT Xcal2, MBRP exhaust, intake... get 32psi if I catch it right. Everything seems fine. Stock engine otherwise. Thinking of doing head studs, turbo, and injectors soon. I gotta buy a car and stop trying to race this thing. it's a truck man! but looks ooooooh so good goin down the strip and scarin ricers!

my 96 probably gets around 20psi but my dads 06 can peg out the 40psi no joke i witnessed with my own eyes!

[CUMMINS_KILLA99]

my truck pegs out at 32 with the ts all the way up and the wastegate unplugged with no load but it does tyr to surge alittle until i shift into overdrive.

i have a stock 96er, the best i can do with no load is 16psi. i don't know what i can do under a load since i don't carry enough to find out.
