Re: Anybody Done This?
I do not think you would be disappointed. I have pushed my engine to 10 lbs. of boost with no problems. Hummer engineers told me the bottom end is tough as it was built to be in heavy pickups and big trucks. They agreed with me though that the top end needs more flow and roller rockers along with roller lifters. As I mentioned there are a few more goodies to be added to make engine bullet proof to run up to 18 lbs. of boost. You would want to add a water meth. inj. system to help make sure your not leaning out even if tuned properly just as a precaution when at WOT.
