FWIW, when Dustin ran at the track he was seeing a little more boost, and at the track or on the street there is a greater load on the engine which will help keep the turbo spooled. He did say that on the dyno the boost dropped off 3 or 4 pounds. On the dyno he was probably seeing full boost at peak torque (3500-4000 rpm), and by peak hp (5500-6000) his boost had fallen off which would explain the high tq, and low hp numbers. I'll bet on the track the boost didn't fall off like that. Combine that with another pound or two of overall boost and it all makes sense.
he was loosing 3or4 pounds on the dyno?? I guess I dont recall that but that even makes more sense. so dustin how about you put your car on a load based dyno.
I know from reading on the net alot of supra guys loose boost on dyno's.

Why does that make 0 sense? Sams old turbo fox made 622hp and 720tq. Why is it so far fetched to make more tq than hp?

comparing a 4 valve with a turbo and comparing a pushrod with a turbo is like comparing apples to oranges. you cant even compare a turbo 2 valve to a turbo 4 valve. a pushrod makes tq from the get go. 4 valves have to be revved to the moon and make no torque, the higher rpms are going to grant higher hp. google 4 valves with turbos and 99% of them are making a lot more hp than tq, i say 99% cause its possible there may be a mistuned 4 valve making assbackwards numbers. unsure if you'd understand this however with your thinking your vortech on a 2 valve was the same as a novi 2k on a 4 valve. they are all completely different beasts.

dustin made 486 at 7lbs and 500 tq on a loaded dyno.
at element he was running 5+ more lbs on an unloaded dyno and dyno'd 465 and 565.
how does that make sense?
now addressing the torque factor.
bolt on 4v's with nitrous see close to 600rwtq and low to mid 400's rwhp on a 150 shot, and you will NEVER see a 4v on spray trap even 120+mph, let alone 124mph, not to mention the tq curve is going to be a lot nicer with the nitrous as opposed to the turbo. what about all the 800-900fwhp honda's running 9's? their tq is less than 500 in many cases. hp has plenty to do with going down the track.
on a ending note im not wanting to argue over something so petty, just think dustin's car makes more power than the numbers he was given at element, and he's too nice of a guy to say anything himself. imo element's dyno is inaccurate. i apologize for the shit slinging.

Ok, I guess I should jump in and say something.
Last year's setup on my car was this. 100% stock 4valve, 9.8 to 1 compression, 7psi and meth, open downpipe. Car made 489 hp and 500 tq on a mustang dyno. Trapped 117 in 1/4.
This years setup. Forged bottom end 8.1 to 1 compression, 15 psi and meth, full exhaust, car made 465 hp 565 tq on the dynomite. And yes I had boost bleeding off on the top end. I was loosing about 3 psi and all of my power and torque was made before 5000 rpms. Car trapped 124 this year. I did turn it up to 16psi at the track but at the top end I was still seeing 15psi of boost. At the track I may be making more power than on the dyno but I would still like to get on another dyno and see the difference.

as of right now I don't know. I would kind of like to put it on a loaded dyno to see what the diferences are. Maybe API's dyno?

on a side note, the boost bleeding, and the lower compression, and the full exhaust, makes a bit more sense...

well maybe if you knew ANYTHING about cars other than putting gas in them would you even try to join in on the discussion.
regardless of his set up, facts are facts, a discrepancy of 100+ hp is lost somewhere.
