hell if a bone stock 4.2 V6 with a single turbo at 13psi makes 362rwhp and 490rwtq out of a V6 then please a v8 turbo will make massive amounts of torque.

The Roots makes Torque at low RPM's, period!
A turbo, you need to spool it up to make the torque. To launch, you need a manual, or a high stall to spool the turbo.
I'm not KNOCKING turbo, I LOVE the idea, but don't knock the roots/screw.

yeah agreed!
I meant to say, I could care less about peak numbers, I am more concerned with the space UNDER the Dyno Curve.
The more space = the more power
I'd rather have a nice smooth power curve on the dyno graph, than one that looks like a Heart monitor with Peaks.
I'm talking about Turbo's IN GENERAL, NOT SAL'S TRUCK!
Now, Knowing Sal's tuning first hand I'm quite certain that his curve will be phenomenal!

Both of you guys need to go for a ride in something thats set up right. A big turbo can drop like a Hammer ! With todays boost controls and turbine wheel designs its not like the old days.
When I had my GN the last turbo I had on it was 70mm on a 235 cube motor and a big flat tappet solid cam and I have never driven anything more responsive than that. But most guys wont go out and spend a good chunk of money on a computerized boost control either and that is one of the keys.....holding the wastegate closed until almost full boost is on line.
The boost lag that you guys are talking about....9 times out of 10 is an early opening wastegate. And if you have the right turbo you don't need ceramic ball bearings and all that. I know guys that have bought those turbos and will never waste the money again.

You guys shouldn't knock the abilities of the turbo, until you see the results. Remember when we all knocked a centrifugal blower on a Lightning? Then I made 700 rwtq with the Procharger and it amazed everyone, even myself. The turbo is just that much better, since it's not tied to engine rpms. Maybe the turbo will suck, maybe it will kick ***. Time will tell. But the initial results are amazing. I've been driving the Lightning back and forth to work and it's been real fun. With only 10 psi, at 1/4 throttle this thing pulls like a **** and blazes the tires at will.

So, as I originally stated, let's see what kind of low-end torque is being produced by these turbo setups. I'm guessing that the peak torque is shifted significantly higher in the rev range. Still waiting for someone to prove me wrong.

With that said my argument was a turbo isn't going to have the near instant low-end torque of a Roots or twin screw. Hell, even MM&FF got it right and showed that a twin turbo setup on a 4.6L showed less bottom end than a twin screw supercharger. Granted, the turbos 'caught' the twin screw at about 3,500rpm and took off from there but the supercharger did indeed have much more bottom end.

Just my .02 cents,

What I expect to happen with mine is that I will have to time limit the boost for a second or two to keep the tires from exploding.
And then bring in the boost as traction will allow. If you watch an 8 second mustang with a 10 wide tire.....thats the only way they can get down the track. I believe the converter that I have new will more than enough to get the job done.
A turbo gives you this option....a blower doesn't.

Quite honestly...if I start seeing guys getting these things into the nines with turbo chargers, I will be one of the first lining up for one. Right now I am just waiting for the guys with endless resources to get all the bugs worked out. I can see the potential is there.
