We run them on Cummins' often enough that see over 100psi on cold start up. 60-80psi running pressure depending on engine condition.
Your turbo has a 60/58mm turbine with a 9cm2 t3 housing. Anything he would have is larger on the hot side. Yours will have more cruising boost...
It is a China knock off Borg. They copied the SXE cover as well.
Your 04 Dodge also has a vastly different turbocharger than what his IDIs would have. Respectively.
Are you sure you do not have an hy35?
A gt45 seems a bit excessive for 400hp.
Play around with matchbot on borg warners site. http://www.turbos.borgwarner.com/aftermarket/matchbot.aspx
Imo you will have more trouble with the torque the 408 is going to make when adding atmospheres vs. limiting horse power. A smaller turbo is...
Thread is almost a year old lol
There we go!
Photos are down.
Tractor pullers I know of are double or triple that pressure. Pretty neat to see the through bolts they use to clamp the block and head together....
Honestly it sounds like your secondary is too small and cannot move enough exhaust mass flow to keep boost (well drive pressure) in sane levels....
The way I have sized compounds is to determine the hp level or desires. I agree we need to know how you are routing the gate. Is it to atmosphere...
I would think an hy35 or he351cw would work well too.
