None of the holset turbos that come on cummins powered pickup trucks (I'm assuming that's what you meant) flow enough air to come close. It would probably take four or five hx-35's to flow close to enough air to make the power that has been discussed.
On the other hand, twin hx-35's would be a great economical way to make a super simple, super street friendly, drive across the country 700fwhp 340.
