Got a buddy wanting to run an HX35 into HX40 combo. Both are wastegated. Question is, do both turbos need to be watsegated the same (35 psi, for example)? How does this work?

Any info on how to make it work would be appreciated.

 

You can run either the HX35 with a larger Turbo or the HX40 with a larger Turbo. It wouldn't gain anything running those turbos together.

Completely agree. Those two chargers are to close in size to get any gain out of them. Tell him to run his hx35 or hx40 with something like an s300.
