Figured you Dodge boys would have more info on a HX55 in a twin setup.Do you think or know if a HX55 with all the goodies (big exhaust housing & compressor wheel)would be too small as the low pressure for a twin setup??

 

yes...

and both turbos are "low pressure"

the pressure is multiplied

just run an HT3B... they work great, and they're cheap as dirt

 

This is for a 7.3 application & I had a S400 that I was going to use but no room if I want to keep the a/c & heater.So my fab/turbo man said that the hx55 with the largest exhaust housing & some custom wheels is what we are going to use.They had been using a H2D before for the street trucks with a bunch of custom mods.
