Well it work with a stock 5.3? I have a 112 I am putting on.

 

I just took it out of my 5.3 because I was in boost too much. I think I saw a little over a 1lb increase just from the cam swap and it was there at a lower rpm than the stock cam. Just seemed like I was seeing boost to early for my application.

 

That may be to much for me to. As I am building my truck mostly for pulling.

 

Boost too early is a problem???

 

If I didn't drive it to work every day I see no problem what so ever.

 

I wonder how it would be with a car and trailer behind it?

 

I think you would be in boost at the slightest bit of acceleration. I saw about 17 in/hg at idle and 5-7in/hg at 65-75 mph. I would typicaly see about 2-3 psi under mild acceleration. I'm sure the 3.42 gears didn't help.

BTW that Nova is sick.

 

Bump.

 

Hmmm. How did it idle? Off topic but how does your air assist work? I am looking and maybe dropping my dually and will need something like this on the back of it I am thinking
