I'd be really curious to see just how much more air a TVS is pushing on a 6.0 at say 8# at 5k RPM compared to a similar turbo with stock manifold/log exhaust at the same boost level. I'm talking with the same heads, and a cam that is correctly "spec'd" for both. I know this is not because a TVS is 'better' at pushing 8# of boost, but its because so much more exhaust can escape that 8# of boost can really mean 2 totally different things there... outside of probably total air in the cylinder when it fires.
Basically what I'm getting at is I think I'm realizing for a low boost aplication, like my LQ9, a supercharger might be a far superior answer to create great power using FI...
I'm sure there is something I'm missing about a turbo set up that will even everything out here... and I really want to understand this. I think the bottom line is I may not have enough of an understanding of what makes a turbo set up great while I am much more familiar with a blower. Everythign I typed makes sense in my head, but I'd love to be proven wrong lol.

I'll add this to the mix. I don't know who this is... but I have a feeling they are a member here.
Those are real impressive numbers on 10# in a cam only 5.3. Add a little displacement for a 6.0 and a 76mm turbo and that looks like a 600 RWHP dyno at only 10#. Pretty awesome.

397.81 RW/HP 446 RW/TQ SAE Corrected.
LQ9, LS6 Cam, Mid Length Headers, Cats, Radix MP112, 3.4 Pulley, 42lb Injectors, Walbro 255lph in tank, EFI Live base tune (Black Bear).
Hope to do a little better once I send back data logs plus I swapped out the crappy flowmaster 40 as well as some more mods to come.

Yea I understand that, but its definitely something worth noting. The turbo's are much more efficient at making boost... theres no question there, but without spending an arm and a leg on a turbo kit they still use the stock manifold on one side... kinda whacky if you ask me. Just by looking at most of the kits I think there is a ton of power potential left in them... look at how much boost supercharged guys lose when they go to a great exhaust system... yet they are stil pushing as much if not MORE air through the engine.

4.8
Patrick g cam (spec'd for procharger), comp cam single valvsprings, stock heads, stock intake, stock tb, stock head bolts, stock mains and rod bolts.
Pt 88 turbo 16 psi/20psi second pull
Snow Performance methanol
No NOS (hate it)
4l80 w/4400 circle D verter with circle D flexplate.
Dynoed on 20's 295/40's
Recently chipped piston #3 due to the stupid vacuum line melted from waste gate.
On a Loaded dyno:
671rwhp/622rwtq @16 psi..........792rwhp/680rwtq @ 20 psi......
16 psi pull
20 Psi pull
