Kyle and I went to Patrick G in Victoria TX yesterday for a little dyno tuning on the 4.8L compound set up. We had issues with the waste gates opening up to soon and not letting the compound kit do its thing. Basically all of the exhaust is bypassing the small turbo and going straight into the big turbo. Once we get this fixed this thing is going to be a beast down low. We were only able to get 12.8psi out of the set up and it made 643hp and 557tq. All of the power is coming in up top so that lets us know the small turbo was just along for the ride. This to me is exciting news, cant wait to get the small turbo spooled up to see what its going to do down low. Kyle is thinking a stronger spring for the upper waste gate and a set of manual boost controllers will do the trick. Either way I am very happy with this set up! Cant wait to see what 20psi will do.

 

Damn! That's awesome

 

Badass, wheres the compound build pics, or did I miss them somewhere?

Pretty happy with it so far, just needs some tweaking

 

Badass!

 

Looks good...
When are y'all hitting the rollers again?

 

Sounds about right for an 80mm on a 4.8 lol

 

Thanks! Taking it to the 1/8 on Friday. Hope it goes well.
