18psi/50 shot made 730/747. Truck best track time is 6.52/106.6. Weighed it two weeks ago at Carolina Dragway, with me it is 4550.

 

How high is your timing?

 

16.5 above 6K

 

I seem to remember coming across a thread of you building a forged 5.3... is this still in the works?

 

Yeah forged aluminum 5.3 is next up. Haven't got to far with it yet though.

 

How high did you get with the LS6 cam? What heads are you running?

 

You were running through a 3'' DP and cutout on these runs right? I wonder if going to a 3.5-4" DP would help any.

Can you change just the turbine wheel and housing somehow?

 

That was with ls6 cam and still on stock heads.

No options there, better off changing turbo all together.

As for dp, I hate to spend a couple hundred dollars and have the same issue and then have cut it off to run a different 4" outlet turbo. Current setup is 3" into cutout.

 

Yea i vote something with ~ 83mm wheel. Be amazed how much better power it can make.
Give it a go!

 

Well if you're making this power with a 3" DP through a cutout a bigger DP most likely wont do much then.


I vote for this badboy right here!
