The stock turbos are capable of spinning up past 80psi according to Navistar engineers, but he also said the heads will lift around 55 psi if I remember correctly.
that turbo that your talking about is great my friend dalles has it on his truck. no its not for sale yet. but ill as him again this weekend about it. where getting over 60psi out of them now just need more fuel. check out of dyno video on youtube.

No way... Not with 80 lbs of backpressure to only make 45 lbs of boost.
Matt told me the stock turbos are at about a 2:1 drive to manifold boost pressures...so 50 psi = 100psi drive pressure. Also he said elites new small turbo is about a 1.5:1 drive to Manifold ratio. The new smaller and bigger is proally even better than that
Are these the same turbos Brett at II told me run for about 2 weeks before the motor lets go?
I dont need to know what Matt tells you, I already know all that jive. Im just stating that the stock trim chargers will never be able to move enogh air to build 80 lbs of boost.
