There is no question that the roots or twin screw blower on a lightning will have more grunt down low then a turbo. The turbo truck should be ALOT faster and more powerful then any blown truck running similar boost levels.

The thing is with turbos, is that you MUST have the right setup. It's a tricky thing, because you've got intake housing, exhaust housing, and impeller size all playing a big factor. And if one of those is not right, the performance will lack. The biggest mistake is putting on too big a turbo. The base engine, in natural form, has to be able to drive the turbo. If the turbo is too big for the motor, it'll bog big time. The key to setting up your powerbands, is the housings. You can have a turbo make peak torque off idle if you want, but then you will lose some top end power, and vica versa. The key is finding a happy medium that still makes the vehicle perform well.
As for the PowerStroke example, since you mentioned the six gun, I am assuming you drove a new 6.0 Powerstroke. On those trucks, the new variable vane turbos are SUPER lazy off the line. My 7.3 hit like a hammer off the line, and my new 6.0 leaves really soft if you just mash it. You need to stall the rpms on the 6.0 to get it to leave hard. But that's completely unrelated to what we are doing with the Lightnings.

A properly sized turbo would be the GOODS.

My powerstroke was a 7.3 with a hot chip, exhaust, intake. It would haul the mail for how big and heavy of truck it was.
I hav to say I wouldn't want to be one of the test mules, but after it is out for a little while and working I would be very ready to step up.

Seriously, while my particular setup may be more than the average person needs, we will have a kit available to the public once testing is done.
I agree on the performance. I truely feel that our turbo kit will strongly outperform any blower you can put on the truck, and not rob any hp from the motor to drive it.
Quick change pulley? Pfft.... How'd you like to go from 15 to 30 psi at the twist of a ****. It's going to be wild
