David Z ran 14.09 @ 98.9 - With a QUAIFE! (flywheel & clutch upgrades) Traction enhancement - his 60' was good too! You bring up Brad's 13.9 as TQ being the only reason he ran that fast. Skipping the part I mentioned about a
2.0 60' 
and using solid mounts & torque strap...
So about the same ET (thanks to traction!) as some S/C SVT's but lower trap speed...
You are not even acknowledging the difference in 60' times... HELLO - THAT'S TRACTION! I've only mentioned it like the last 5 posts??? What gives???
Since traction is a major problem now - More torque would only make it worse (just ask Brad about this one!) and therefore SLOW YOU DOWN with slower 60' times. Heck even 330' times...
Why do you not get this simple idea?
Yes the diff will not like better traction. Yes it may break. That's where a LSD comes in. But heck - they diff breaks on stock SVT's... So what's your point? Don't get better traction out of fear???
As for bogging down... Ever heard of clutch slipping. Pro racers have transmissions with "adjustable slip" so to speak. Us normal folks just have to do it the old fashion way and "practice"
I've seen several turbo's run 10's with normal redlines (~7k - A friends 10.6 second Conquest TSi {with IRS even!} comes to mind)
...and yes there is the Nitrous'd Honda crowd that spins to 8k. No low end torque there, but they seem to run fast for some odd reason... There's even a local Normally Aspirated Honda that is almost in the 11's. You know that has next to zero torque... What's he run - drag slicks for traction...
