I don't believe the KB needs only 80 HP vs the TVS 150 HP at same boost / engine RPM Even a belt drive centrifugal turbo is not that efficient. KB may be aroud 105 HP.
I think you research twin screw superchargers a little more. Heres a start fo you:
Kenne Bell 3.6L Twin Screw - Muscle Mustangs & Fast Fords Magazine
and
Mustang GT500 Supercharger Tests - Throttle Body - 5.0 Mustang & Super Fords Magazine
and those articles are 2 to 3 years old.
Thanks for the links:

All these ideas sound good on paper, but would all of the improvements equate to more power? To find out, we ran a series of back-to-back tests using a Shelby GT500 Super Snake comparing the 2.8L H and the new 3.6L. The first test was actually performed by Kenne Bell on its blower dyno. Running both blowers at identical boost (24 psi) levels demonstrated that the 3.6L require just 177 hp to spin compared to 217 hp for the 2.8L.

Sure if you drive the TVS off its compressor map, there can be 70-80 HP difference in power, but a TVS has similar eff to a TS apples for apples.
So your telling me that 5psi increase in boost = 198 rwhp? I don't think so! If that was true we all could just do an upper and lower pulley swap for 800 rwhp. Where does all that extra hp come from? I would love to know that.
5 psi more in boost from a much larger and much more efficient blower. Doesn't sound too far fetched to me...:shrug:
In the Nov 12 Issue of MM & FF (article not available on line yet) they put a KB 3.6L on a bone stock 13 GT500. Dyno'd bone stock was 603 rwhp. (15psi Boost). Dyno'd with KB = 801 rwhp (20psi boost).

The highlighted part above is correct!
Unfortunatey and embarassing to say, I fall in this category!
There seems to be more than meets the eye on this one!!
Guess I am not getting 900HP from just a KB bigger blower!
And even if I did it wouldn't be stable! DAMN IT!!!
NO MODS NO MODS NO MODS!!
I took a video of this thing idling this past weekend. It sounds almost like my old S-Trim. Watching every run it made, I was a little disappointed, although my expectations were very high. I know the power was there, they just couldn't get this thing to make a perfect pass which was frustrating. I have a feeling an automatic will be in the tunnel in the near future. I really hope not, but I see it..:bored:
