Positive displacement turbo. Say what?!

[WSSix]

Ok guys. I have been looking into building a turbo setup for my LT1. This isn't anything that is going to happen soon. I'm just looking into it and learning. I had planned to go with a Gen3 6.6 engine but after I wrecked my Formula, I had a perfectly good LT1/T56 combo to use. I thought why not, it'll be different.

Here's my situation though. I want torque everywhere. Can I build a turbo setup for my LT1 that will act in the same manner as a positive displacement blower such as the Magnacharger? Now I realize that I won't be able to get instant torque off idle like the Magnacharger. I would be fine with it coming in at say 2500 and holding til 6000 or preferably higher. Is it possible that I can get the same type all around stroker performance I would have gotten with a 6.6 Gen 3 with a turbo LT1? I'm only looking for around 500 rwhp and as much torque as I can get everywhere. Everything I am finding is geared towards drag racing. This is a street car.

If someone really wants to make me go crazy about which way to go, find me a bell housing designed to hold an LT1 T56 behind a Gen 3/4.

Thanks
