your take on BOV's and WG's

The cummins turbo should work pretty well for you with atleast a 38mm WG. However i think it will build boost under hard throttle alot faster than you're expecting it too. Mustang SVO and turbo coupes (2.3l engines) that are modified often run a single HX35. For street use it may be alright as long as you aren't running too high of RPMs. While cruising and regular driving you won't see boost at all, but if you get on it I would expect boost to come in in the lower 2000rpm mark.
