Turbo experts please.
My motor was overboosted once.....2 cracked stock pistons.
Alot of people say the deltagate is crappy, when you buy the T76 kit you get an upgraded WG. Maybe its time to upgrade anyways??

If it doesnt change a bit at WOT then youre out of turbo.
Like I said, just have race gas in the tank is case the boost jumps up faster then you can react to close the throttle.

So if I blocked off the wastgate I would Totally over boost my motor up untill 4000rpm
yes sounds like the turbine is stalling from the excessive pressure.
his built motor is making a lot of exhaust on that bank.. apparently too much for the little 60hifi housing to pass.

whats your maf reading? at 13psi on a mostly stock 6.0 i often max my maf by 5000rpm, i would say i am at 65lb's of air or higher.
the kit i have has a 2.5" cross over, 2.5" log and a 3" down pipe. with a t76 my boost presure holds steady.
i would think with ported heads you are flowing more air than me and just runing out of turbo.

I agree with MM, the turbo is just too small. Get that T-76 on there and I think it will hold boost to redline. May spike because of the small wastegate, but it will hold to 6200 rpm.

My MAF is right at 439gms/cyl @ 5800rpm so it`s pretty much maxed. MM does the T76 have a larger exhaust housing or would I need to go with a larger A/R to lower back pressure?

yea, I can't wait to get the new turbo. I'm also working on getting a engine managment system that uses a 3bar map sensor to replace my stock ECU if that all works out i'm shooting for 600rwhp or more.
