I'm running stock converter and trans in mine and it's my DD, does fine, holds power and stills drives nice from stop light to stop light. You had better budget a Detroit Truetrac bc the g80 dosen't like PD blower torque.... Lol....

On the G80 subject this is second hand info so you know how that is but I understand what kills them so quickly is uneven traction such as one wheel off of pavement or doughnuts and such. Parish 8 I believe was his name (the father of turbo 4wd) ran some badass #'s on a G80. I thought it was 10's. Maybe make the time bomb last a little longer if you avoid the above stupidities lol.

Mines was an 8.6, I cracked carrier housing in 2 places. I do a lot of burn outs and power sliding so I wasn't shocked when I whacked it. I'd still budget for it, it's a ticking bomb that when it goes can really f some stuff up badly.

My 2010 Silverado ext cab (4wd) is going under the knife for a 2.3 Whipple and other supporting upgrades- bouncing off the walls looking forward to it!
The question is what are realistic numbers that I should expect? For reference, the truck is currently bone-stock (LC9 engine) and very low miles but doing the following:
Whipple Supercharger W140AX (2.3L)
6-rib pulley 3.5"
Stainless Works Stainless long tube headers (3.00" slip fit collectors) w/high flow metal matrix catalytic converters
Stainless Works catalytic converter-back exhaust system (2.50" inner diameter) Dual under bumper exit
MSD Ignition spark plug wires
DEI Spark plug wire Protect-A-Boot sleeves
ARP Cylinder head bolt kit-chromoly, Pro Series, 12-point head style
Dual valve spring kit maximum lift: .660
Comp Cams Hi-Tech chromoly pushrods
CNC port/polish heads and 2" intake valves
LS7 hydraulic valve lifters
Custom designed billet-core camshaft - 3-bolt conversion
LS2 timing chain damper
Katech Performance Parts C5R/C6R timing chain
Melling High Volume Oil Pump
LSx 160 thermostat
Walbro 450lph (E85 Compatible) Fuel Pump
Full dyno tune
Interested in what kind of numbers others with similar builds have seen...
Thanks in advance!

So, what did your rig end up running?

With your setup, I'd expect more but you didn't mention if your truck is 4wd. Mine is and mention it for 2 reasons- the extra parasitic drivetrain power loss hides the gains and it would be REALLY challenging to drive in the rain without 4-auto!
