I also think you would be slightly over 1000 whp at 165 trap speeds and your weight(3100 right?), but I guess it depends on what dyno or calculator you are using. On the 4 trial passes I have made, I completed 1 (bias ply = pucker factor) and only went 138 and was pissed, but I figured a 3/4 tank of fuel, 150 lb stereo, c5z, tt crap, c6 drivetrain/coolers and with me at 260 I'm pushing 3700lbs which should be ~750whp depending on the calculator which is close to what it dynoed. I actually picked up 36mph out back which seems crazy for the overall mph. I'd have to check logs to see what it actually hit for boost so ~13-14 psi.
I don't have any ax to grind, your car runs great man and I do remember your rx7 example also. I've also seen plenty of cars on this forum swap to a auto and actually pick up mph due to not quite putting together a good manual run. All I'm really getting at is **** happens and the first or second outing doesn't always end up with the final et or trap speed the car is capable of.

3280 raceweight when I went so prolly little more than 1k, but still close
You are on to it here exactly with what you said though
The softer and more shitty the leave it hurts us for sure at the 1/8 no doubt, but we get it all back or close to by the 1/4.
The harder we leave and get rolling our 1/8 responds, but not really our 1/4, sure maybe a couple mph
Like you said you gained 36mph, start getting after the leave and that will drop but not really effect the 1/4
If photo bucket was working for me I'd post the slip of the yellow FD. It picked up 45mph....

45 mph is rolling. Does he run a radial or bias ply at the track? The bias leaves so soft and easy on parts but feels like **** up top. It was just a 2.0 60 ft on a 26" 10.5 16" et street and I want to put a 28" real slick on with a quality front runner. I never got the technique down and only went on a test and tune day. As for me I have all sorts of issues with the setup. The largest is traction and shifting as my rxt is too close to the floor causing some clutch drag and I end up buzzing 3rd trying to hit it fast. So a shim or tick master needs to be looked into after trying a pressure bleed. Just need some seat time and spend some moldy money.
My car is a terrible car to drag race, still fun, but so spendy to fix I'm a little chicken to kill it. It went just .2 slower NA, with almost 20 less mph on a damn 18" nitto dr. I'll get it more respectable at some point, but for the most part I live out my 1/4 life through friends running the 10.5 stuff down here. Hard to keep up with those guys anymore without a purpose built drag car that doesn't see much street time. Once I get a shop for more space I will for sure be building some sort of street/drag car that has a solid drivetrain in it even though it will only be good for test and tune really.
About 15 years ago in my DSM I was running high 11's and the mph would usually be around 114, but also quite a few 112's-116's. That car had a ton of passes in it for practice. Most days I would roll in to the track running low 12's and chip away at with practice. The MPH did not change a lot, but still had a bit of swing. It could have been slight tuning changes, etc. it's hard to say.

I think im one of a handful of people to use the bigger t4 cx gt35s
Denmah had a set choke bad on his 6.0 and it steered everyone away from them.
I made 730 through an unlocked auto with them on a 5.3 at 17psi
I think they would have touched 800 with the gates pinned
Im pretty confident they wouldnt make 1001 on any ls engine

I feel like you are missing the point…
Your car is a horrible example and shouldn’t be used as a comparison to anything IMO. No one in their right mind would put 4.10 in the rear and try to run out the 1/4 in OD at 150-160. Makes zero sense and is just asking to break something. .

And yes very well set up M6 car will trap/ET similar to an Auto cat, but mine is far from that. Its also been shown many, many times over that high HP cars TRAP and ET typically better with the switch to auto. Thats why rotaty's argument for my car is is so ridiculous.
Yes, you did. Again this is from experience, not assumptions.
First pass is on street tires, same settings I had when I taped 146mph the same day on slicks (9psi to the 8th, 15psi up top). I was down 14mph at the 1/8th that pass. No magic would have made that up.
You have an open invitation. When should I expect you?

When I retire or my wife actually removes my ***** for some reason, I'd love to do this with a purpose built motor/chasses/PG car. 7s for 7k?
Can you even imagine the hate?! 
4 Bolt heads would be doing a dance the entire pass I'm sure!

Sorry a t56 is not going in my car. Probably the most overrated trans out there IMO
Send me a GF-5R with road race sliders and it will go in.... And be both faster in ET and trap than now on the same tuneup
Plus I don't get the whole street car slang thrown around with a t56 vs that a glide isnt somehow. All I do is street and the numbers speak for themselves.

Kind of chuckling the high HP goes go faster on autos just because.
Manual is the faster more efficient trans. Wonder why in HP limited classes you are running a manual if it is legal

The T56 is the most common drag raced manual behind LS engines. If you can't get it down the track then that's your problem. If a T56 holds up to a an fbody running 8's and 4000lb sedan running 9's it's perfectly fine.

Has anyone tried the REV-9 Typhoon TX 72-68, 96AR, on a T4 flange with a 4in V band down pipe? Would it be to laggy on a twin 6.0 set up? I'm not smart enough to post a link, but it looks like a good quality turbo for a china deal.
