Turbo boost pressure low????
Hey guys i have a 1994.5 F350 with the powerstroke. Iam just wondering if my turbo is worn out of is it normal for it to have about 17-18psi under load. here is the info on my truck..
motor-170k on it,5speed
fte cold air intake,3in down pipe to 4in straight pipe,banks bighoss stage 4 chip, stacked with the edge-ez, 99 superduty intercooler, boost and egt gauge..now before i put the intercooler on the truck the boost was still at 17-18 psi so i know since ive installed the intercooler there isnt any leaks there. this boost reading is underload reving the heck out of the motor..now is it normal for it to have these boost readings? I just see some superduty's running around here with 30psi with the same mod's. i understand they have a diffrent turbo, but why is my boost psi so low???any help would be great thanks

Like Luke said, more fuel makes more boost. So your about right. With my set-up in sig. I can only get 20psi pulling real hard. One thing you can check is the condition of the compressor wheel, see if its dusted a bit, but still your sounding about right. What side of the intercooler are you reading boost??

First injectors then a superduty or larger turbo? i understand the superduty turbo's have diffrent tube sizes and what not, but iam not worry about fabin up some pipes and what not..

Your turbo is good enough to support 400+ hp with, been there done that 
. Look at www.beansdieselperformance.com for fuel 
. Oh and dont waste your time by putting a superduty turbo on your truck, unless your going to upgrade to a ball bearing turbo. Our stockers are better than a stock superduty turbo anyway. If you want to upgrade turbo, go with a hypermax h2e. You will need more fuel to spool it, stock injectors wont even begin to light that turbo.

Hmmm...wet manifold diesel injection. Cool idea. I would speculate that the manifold fuel would ignite prior to the injector firing, so it would be similar to the pilot shot of a split shot injector.
I think you would want to take the same precautions neccessary with a propane system...too much fuel too early in the cycle could put you in a bad way.
