looking for supercharger!
doug, I can't explain it any other way. Look up what tq is online or something - tq is hp with engine speed factored in.
if you look at all the high hp cars, they have high tq up high towards redline too. Peak tq at 4000 rpms has nothing to do with tq at redline. All it means is there's some more area under the curve and that there's more power available for launching. Even car like vortech Z's that don't make much peak tq, but make a lot of hp up high - they make a lot of tq up high.
A C6 has around 300 tq at the wheels right at 6000 rpms and 270 at 6500 rpms. A 450whp vortech car has about 370tq at 6000 rpms and 360tq at 6500 rpms. As you can see the tq would be quite a bit higher, which when you factor in engine speed, means hp is higher as well.
I have nothing to prove, but I know guys who run 12.4-12.7 very reliably with the vortech with only 370whp and an auto. Look up cj350 on 350zmotoring. He was using stock wheels with bridgestones. He even shifts 500 rpms before redline in his auto to make sure it shifts before hitting the rev limiter. I'm making this really huge assumption I know, but I was kinda thinking another 80 whp, way stronger gearing, better tires, lighter drivetrain etc would produce better times than even his car.
Just saying, even with 410whp, a vortech I think feels stronger than a C6 from my own experience driving my dad's C6. Another 40-50whp and I think the car falls somewhere between a C6 and a Z06, leaning slightly closer to the Z06

Then I'd like to race you, because I don't see that happening.

here's a dynojet graph of a C6 (and a C6 with an exhaust for the higher curve) - a manual of course. And here's what a 450whp vortech would look like if it was overlayed over it. This is just for the sake of comparison. If anyone doubts it's a real vortech curve, look up 450whp vortech dynos and compare it - same general thing
the green line is vortech HP, blue is TQ.
I know dynos are not 100% comparable, but this is a ballpark comparison anyway
the graph speaks for itself, not much else for me to say. The C6's tq drops way off up high, while the vortech's is still strong because it's getting more and more boost as it gets higher.

ok i hear you on all that.. but you didn't answer my TT Z and SC Z comparison question
oh sorry, must've skipped over your question and got carried away on the first part of your post.
In terms of top end performance - whp is whp. The person who'd win is whoever has more whp area under the curve in the WOT range.
We all know turbos are more efficient than superchargers, but whatever power makes it to the ground is what's measured at the end of the day. Turbo Z's have a broader area under the curve than a SC. So with everything else being equal, if you have a 450whp vortech, and a 450whp turbonetics, yeah the turbonetics would have the clear advantage. It's peak tq would be way higher at around 4500 rpms or so. In terms of racing, the hp curve in that area would also be higher
We all know ST dynos tend to look like the hp shoots up to to peak at around 5500 rpms or so, then pretty much hold that power to redline.
If the vortech only reaches that peak hp at redline, then it obviously isn't making as much power at 5500 as the ST, and the ST would walk the SC.
If you start changing other things on the car though, things start getting interesting. A 3.9 final drive on a vortech vs a 3.3 final drive on a ST are two totally different animals and if both cars have traction, it'd be a much better matchup IMO despite the ST having more area under the curve because there's a 16.5 % difference in gear accelleration between the 3.36 and 3.91 FD.
