Another cool turbo combo. Considering what is invested (not saying it doesn't cost money) that is pretty remarkable time. To run that in that weight of car without the turbo would take a serious n/a engine or a decent n/a with significant spray. And the thing seems reasonably quiet!

She is not very loud. Exhaust is coming thru hood. I also have the ls turbo manifolds made by holley. People said they will not be good enough beyond high 9s.

If it is the ones I have seen, they may even say hooker on them. I can't imagine those being a bottleneck at all. I have 1-5/8" primaries on my headers, and I'm not even positive they are a bottleneck.

Pretty much the same engine setup as in my truck, except I run FI.
I use a log manifold sim to Holleys, except the turbo sits on the manifold.
I have about 1000 lbs more weight though, lol. Your 8 sec pass is coming.

I run those same manifolds on my 5.3/S480 combo. At 3400# on C16 (23.5#) I've been 8.74 @ 151. They will make 1000+ for fun. There's a little left (maybe 100 hp) in my combo as well.
