LB7: Factory intake hp/airflow limitations

[diesel53]

Guys,

I have the factory box and intake on my truck. Box is opened up for cool air and has a k&n filter. If I add a 64mm turbo is this intake going to flow enough or is it limiting?

I don't see why it would limit given the size of the turbo inlet but curious if this has been Dyno proven to impede power.

I don't know if it has been A/B tested on a dyno, but the conventional wisdom is a modded stock airbox (like yours) is good to about 600 HP. So with a 64mm turbo, it shouldn't be a limiting factor in any meaningful way. I'd leave it.

It seems like it would not limit me. Tubing size all appears bigger than the turbo inlet. I'll leave it and see I guess
